How to Capture Web App Screenshots Without Login or UI Interruptions Using API

Every time I’ve had to grab screenshots from complex web apps, it felt like jumping through hoops. Logging in, closing annoying pop-ups, cookie banners blocking half the screenthese hurdles turned what should be a simple task into a frustrating ordeal. If you’ve ever wasted time trying to get clean screenshots without all the distractions, you know exactly what I’m talking about.

How to Capture Web App Screenshots Without Login or UI Interruptions Using API

That’s where the VeryPDF Website Screenshot API for Developers completely changed my game. Instead of fiddling with browser extensions or manual cropping, this tool lets you capture perfect web screenshots through one straightforward API call. No login hassles, no messy UI elements, no wasting hours cleaning up images afterward.

Here’s the deal: this API is built for developers, QA engineers, marketers, or anyone who needs reliable, automated screenshots of web pages especially when you want them clean and distraction-free.

What is the VeryPDF Website Screenshot API for Developers?

In simple terms, this API lets you automate website screenshot capture without the usual headaches. You don’t have to run or manage browser clusters, deal with flaky automation scripts, or constantly update blockers for cookie notices or chat widgets. It handles all that for you, out of the box.

I discovered this tool while working on a project where I needed to document multiple web app interfaces regularly. We had previously tried DIY solutions using Selenium or Puppeteer, but the results were inconsistent. Cookie banners popped up, social chat widgets overlapped key areas, and ads spoiled the layout. Switching to VeryPDF’s Screenshot API was like a breath of fresh air suddenly, screenshots looked professional, every time.

Key Features That Make This API Stand Out

1. Block annoying UI elements automatically

Forget the hassle of manually coding rules to hide cookie consent banners, GDPR pop-ups, ads, or chat widgets. The API comes pre-loaded with a constantly updated database of 50,000+ rules and heuristics that block these nuisances effortlessly.

For example, I was testing a retail site full of dynamic cookie pop-ups and aggressive ads. By simply adding a parameter to block those, the screenshots came out clean without a single banner in sight. This saved me hours of manual edits.

2. Flexible rendering options for any scenario

This API isn’t just about snapping screenshots. It lets you customise how your screenshots look:

  • Dark mode rendering for sites that support themes or want reduced brightness.

  • Hide specific elements or simulate clicks to reveal hidden content or close overlays.

  • Add custom JavaScript or CSS so you can tweak the page just before capture perfect for tricky cases.

I once needed a screenshot of a web dashboard in dark mode, with certain menus hidden. Adding a few lines of custom CSS through the API options made it effortless.

3. Full-page and Retina display support

Want to capture entire scrollable pages including lazy-loaded images? No problem. The API scrolls through the page, triggers lazy loading, and snaps a full-page shot. Plus, it supports high-resolution Retina displays, ensuring crystal-clear images.

On a project where clients required high-res screenshots for mobile previews, this feature saved me from painful guesswork and pixelation issues.

Real-World Use Cases

  • QA and testing teams automating visual regression testing without worrying about flaky UI elements.

  • Marketing teams capturing consistent, clean screenshots for presentations or social media.

  • Developers documenting web apps or creating snapshots for changelogs.

  • Compliance officers who need to archive proof of what a web page looked like on a certain date clean and unobstructed.

  • E-commerce businesses showcasing product pages without cookie banners or distracting ads.

If you ever needed screenshots without logging in manually or clicking away cookie notices, this tool’s for you.

How VeryPDF’s API Saved Me Time

Before switching, I’d spend hours manually closing pop-ups, cropping images, or scripting complex automation. Now? One API call does it all.

  • I automated screenshot generation across dozens of pages.

  • No more flaky scripts breaking due to unexpected modals or chat windows.

  • Saved countless hours editing images to remove cookie banners and ads.

  • Got consistent, high-quality screenshots across devices and screen sizes.

  • Support team at VeryPDF was incredibly responsive, quickly addressing rare edge cases.

Compared to other tools I tried, VeryPDF’s API stood out with its simplicity and reliability. Many tools require you to write extensive code or maintain your own browser clusters. This API abstracts all that you send a request, and get a perfect screenshot back.

Why You Should Give This a Try

If you need clean, automated website screenshots without dealing with login screens or UI interruptions, this API is a no-brainer.

I’d highly recommend this to anyone who deals with web app screenshots regularly developers, testers, marketers, compliance teams you name it. It’s saved me hours and headaches, letting me focus on work that actually matters instead of fiddling with tricky UI blockers.

The Most Reliable Screenshot API for Daily Capture of News, Blogs, and Content Feeds

Posted on

The Most Reliable Screenshot API for Daily Capture of News, Blogs, and Content Feeds

Every morning, as I check my news and content feeds, I face the same headache: grabbing clean, consistent screenshots across dozens of websites. Ads pop up, cookie banners block the view, and inconsistent rendering makes automation a nightmare. I wasn’t alone in thisanyone who needs to capture web content regularly knows how frustrating it can be to deal with these obstacles.

The Most Reliable Screenshot API for Daily Capture of News, Blogs, and Content Feeds

That’s when I stumbled upon the VeryPDF Website Screenshot API for Developers. This tool changed how I approach daily web capture by automating everything with one simple API call. No more juggling browser clusters or dealing with quirky pop-ups. Whether you’re a developer, content manager, or just someone who relies on snapshots of websites, this API streamlines the process beautifully.

Why the VeryPDF Website Screenshot API Stands Out

I’ve tested a handful of screenshot tools before, and most fall short when handling real-world website nuisances. Some can’t block cookie consent banners, others struggle with ads, and none handled chat widgets gracefully. VeryPDF’s API, however, offers a robust blocking engine with over 50,000 rules for ads and cookie banners that works like a charm.

Here’s how it helped me:

  • Ad and Banner Blocking with a Single Parameter: I just add one flag, and the API cleans out annoying ads and GDPR consent pop-ups. This means I get clean screenshots without manual intervention.

  • Hide Chat Widgets and Pop-Ups: Social media chats or support widgets often ruin screenshots. The API’s blocking engine removes those, giving me professional, distraction-free images every time.

  • Dark Mode and Custom Styling: For clients who prefer dark-themed snapshots, I can toggle dark mode or inject custom CSS and JavaScript. This level of flexibility made my presentations look slicker without extra coding effort.

Perfect for Developers, Content Managers, and Digital Archivists

Who exactly benefits from this?

  • Developers who need automated, reliable website screenshots integrated into apps or workflows.

  • Content managers capturing news, blogs, or social media content daily.

  • Digital archivists wanting accurate records of web pages over time without manual intervention.

  • Anyone running marketing monitoring or brand reputation management who needs clear, consistent web captures.

I’ve used this API for daily blog content curation. It ensures that every screenshot is consistent, complete, and free from those pesky cookie banners or chat pop-ups that used to slow me down.

Key Features I Loved Using

1. Full-Page and Lazy Load Rendering

Before VeryPDF, capturing full-page screenshots often meant missing content due to lazy loading images or infinite scroll issues. The API handles scrolling and triggers all lazy-loaded images automatically. The result? Perfect, full-page captures that look exactly like what you see on screen.

2. Device-Specific Rendering

Sometimes I need screenshots that look exactly like they would on an iPhone or a high-res Retina display. The API supports custom screen sizes and predefined device profiles. It’s handy for testing and showing clients what their sites look like across devices.

3. One API Call Simplicity

The best part is the simplicity. A single API request does everything from loading the page, blocking distractions, applying dark mode, to producing high-quality screenshots in formats like PNG, JPEG, or even PDF. This saves hours of scripting and testing.

How This Tool Saved Me Time and Frustration

I used to spend hours writing scripts to handle every new cookie banner or ad blocker update. Every time a site changed its layout or popped up a new consent form, my scripts broke.

With VeryPDF’s API, this became a thing of the past.

  • Automated blocking removes the need for constant script updates.

  • Exhaustive documentation and SDKs made integration a breeze.

  • Quick support meant any rare edge case I encountered was fixed within hours.

Instead of wasting time babysitting the capture process, I focus on using the screenshots for content, analysis, or client presentations.

Why I Prefer VeryPDF Over Other Screenshot APIs

Some APIs require complex setup of browser clusters or fail to keep up with new ad formats. Others are expensive and slow.

VeryPDF balances:

  • Speed fast rendering and image generation.

  • Reliability handles the messy bits of real websites with ease.

  • Customization from dark mode to custom scripts.

  • Affordability it’s a practical choice for daily use without breaking the bank.

Final Thoughts: Why You Should Try VeryPDF Website Screenshot API

If you’re looking for a reliable screenshot API for daily capture of news, blogs, and content feeds, I can’t recommend VeryPDF enough.

It’s saved me countless hours of manual work and headaches. Plus, it produces clean, professional-looking screenshots that make my content stand out.

Screenshot API That Works Seamlessly With CICD Pipelines and Monitoring Tools

Posted on

Screenshot API That Works Seamlessly With CICD Pipelines and Monitoring Tools

Every dev on our team used to groan whenever we hit that one task in the backlog: automated screenshot capture.

Screenshot API That Works Seamlessly With CICD Pipelines and Monitoring Tools

You know the drill. Your product team wants screenshots for visual regression testing. Marketing wants previews of dynamic pages for dashboards. And compliance? They want timestamped snapshots of key flows across a dozen environments.

We tried Selenium. Puppeteer. Headless Chrome clusters in containers. I spent more time managing browser crashes and headless edge cases than shipping features.

That’s when I found VeryPDF Website Screenshot API for Developers and honestly, I wish I’d known about it sooner.

A Screenshot API That Actually Gets It

I stumbled on VeryPDF’s Website Screenshot API after searching for a cleaner way to automate full-page captures across staging, production, and preview links.

And I don’t mean just snapping a quick PNG.

I’m talking about full-page, ad-free, banner-free screenshots, rendered perfectly for any screen size, with dark mode, Retina display support, and even lazy-loaded elements triggered automatically.

This thing is purpose-built for developers who are sick of duct-taping solutions just to get clean screenshots into their CI/CD pipelines or monitoring dashboards.

Who This Is For

If you’re:

  • A DevOps engineer integrating UI testing or monitoring into Jenkins, GitHub Actions, or CircleCI

  • A QA lead who needs pixel-perfect regressions across environments

  • A frontend dev capturing changelogs or visual diffs

  • A product manager wanting automated screenshots for documentation or audits

  • Or even a startup founder who just needs scalable, reliable screenshot automation without a headache

This tool is going to feel like a cheat code.

Why It Works So Well

Let me break down the three biggest wins that sold me on it:

1. Ad Blocking, Cookie Blocking, Widget Blocking Done for You

Most pages today are landmines of overlays.

You load a URL, and boom: cookie banner, chat bubble, newsletter pop-up, sometimes all three.

VeryPDF’s API solves this with built-in blockers that just work.

  • One parameter = all the clutter gone

  • Blocks 50,000+ types of cookie banners

  • Hides annoying social and support widgets

  • Keeps your screenshots clean, professional, and consistent

I used to write custom JS for this. Now it’s one flag in the API call. Massive time-saver.

2. You Get Pixel Control Without Coding Hacks

With other tools, if you wanted dark mode? You were injecting JS.

Wanted to scroll to load lazy content? Write more code.

With VeryPDF:

  • Dark mode rendering is a toggle

  • Trigger lazy-loads for infinite scroll and dynamic content

  • Hide selectors or click buttons before capture

  • Add your own JS/CSS if needed

You can simulate real-user views, down to the pixel but without needing a browser lab or scripting rabbit holes.

3. Built for CI/CD and Monitoring Tools

Here’s where it clicked for me.

This isn’t just a screenshot API.

It’s a CI/CD-ready screenshot API.

  • Simple URL-based API calls

  • Works in shell scripts, CI pipelines, and cron jobs

  • Call it from Node, Python, Bash, whatever

  • Supports PDF, JPG, PNG, MP4, and GIF outputs

I dropped it into a GitHub Actions workflow in 15 minutes. Boom every deploy gets a clean PDF and PNG of the app’s homepage, ready to review or archive.

Real Talk: The Edge Cases Actually Work

We all know the pain.

You find a promising tool until you hit some weird edge case.

Well, I ran into one too a React-based dynamic dashboard with WebSockets and lazy content. I pinged support, not expecting much.

Dmytro from VeryPDF hit me back within the hour.

Tweaked the engine. Issue resolved. Screenshots perfect.

That kind of response is rare. And that’s why I’m sticking with this long-term.

Use Cases I Didn’t Expect (But Now Use Daily)

Let me toss in some bonus uses that surprised me:

  • Documentation: Auto-capture and insert product screenshots into internal docs or Confluence

  • Audits: Weekly snapshots of your app’s main flows for compliance

  • Error Reporting: Capture visual states when a test fails, directly in the bug ticket

  • Marketing Dashboards: Feed clean, live page previews into Notion, Airtable, or internal tools

  • Client Reports: Screenshot customer-facing pages and compile into PDFs via API

If you’re even remotely responsible for a product’s visual layer, this tool will earn its keep.

My Verdict? Game-Changer

If you’re sick of hacking together screenshot tools…

If you’re tired of writing custom logic just to clean up a page…

If you need screenshots that are accurate, clean, and automated…

I highly recommend VeryPDF Website Screenshot API for Developers.

Yes. Just hit the API with a standard HTTP request. Works great in shell scripts, Python, Node, etc.

2. Does it work with websites that use lazy loading or infinite scroll?

Capture High-Resolution Website Screenshots for Marketing Teams Using a Simple API

Capture High-Resolution Website Screenshots for Marketing Teams Using a Simple API

Every marketing team knows the struggle.

Capture High-Resolution Website Screenshots for Marketing Teams Using a Simple API

You’re prepping for a pitch. Or maybe you’re building a case study, a client report, or revamping the company website. You go to grab a quick screenshot of a competitor’s landing page and bam, the nightmare begins.

You’re stuck cropping, editing, trying to scroll just right, blocking out that annoying cookie banner, and hoping the resolution holds up when you embed it into your deck.

Been there. Too many times.

That’s when I hit a wall and thought: There’s got to be a better way. That’s how I found VeryPDF Website Screenshot API.

Let me walk you through exactly what it is, how I use it almost daily now, and why it’s an absolute game-changer for anyone in marketing, content creation, dev teams building dashboard reports anyone who needs clean, high-res website screenshots without the mess.

H1: What is VeryPDF Website Screenshot API?

This isn’t your average “hit print screen and hope it works” tool.

VeryPDF Website Screenshot API is a cloud-based tool that does one job capture pixel-perfect, full-page website screenshots via a single API call and it does it incredibly well.

No browser setup. No Chrome extensions. No fiddling with dev tools.

You just feed it a URL, add some options (like screen size, dark mode, block ads), and boom it sends back a full, clean image, PDF, or even a scrollable MP4 if that’s your jam.

It’s built for developers, but I’m not a full-time dev and I’m using it with ease. So yeah, you can handle it.

H2: Who’s This For? (And Why You Should Care)

If you’re in marketing, SEO, design, analytics, or product dev, this tool is for you.

It solves real-world problems like:

  • Taking clean screenshots for client reports and pitch decks

  • Capturing long pages (without stitching 15 screenshots together)

  • Auto-removing GDPR banners, ads, pop-ups, and live chats

  • Generating device-specific previews (e.g. iPhone screenshots, desktop, tablet)

  • Showcasing before/after UI changes

  • Creating training manuals or case studies from live pages

  • Building automated monitoring or reporting tools that grab website snapshots on the fly

We used to spend 3040 minutes a week doing this manually.

Now? Less than 5 minutes. Fully automated.

H2: What Makes It Stand Out?

Here’s where the VeryPDF Website Screenshot API punches above its weight class.

1. One-Line API Simplicity

All it takes is a simple GET request:

bash
https://online.verypdf.com/api/?apikey=XXXX&app=html2image&infile=https://example.com&outfile=example.png

That’s it.

No need for Puppeteer scripts. No Docker containers. No headless browsers to manage. They handle all the edge cases including lazy-loaded images, dynamic content, animations, and more.

2. Clean, Custom Screenshots

This part blew my mind.

You can:

  • Block ads and popups with one parameter. No extra filters or plugins.

  • Kill cookie banners automatically. Their database has over 50,000 heuristics and it just works.

  • Hide chat widgets that clutter the screen.

  • Click buttons, scroll, inject custom JS or CSS, or render in dark mode. It’s fully scriptable.

  • Define screen sizes or simulate specific devices (iPhone, iPad, Android, desktop, you name it).

I needed a screenshot of a product page with dropdowns open and animations paused.

Pulled it off with a single API call. Unreal.

3. High-Res Retina Output

We’ve got clients who are very picky about image quality in slide decks.

I needed screenshots that didn’t blur when zoomed or printed.

VeryPDF supports Retina-quality images and vector PDF output, which meant we could finally stop photoshopping low-res web captures.

H2: My Real-World Use Case

Here’s exactly how I’m using it now.

We run weekly competitor audits.

Every Monday, our script hits a list of 25 competitor landing pages, captures full-page screenshots (PDF + PNG), saves them to Google Drive, and emails the team with a summary.

We’re using the following:

  • Custom screen sizes (to match desktop vs mobile)

  • PDF output (for client-facing decks)

  • Lazy loading + animation pause (so everything renders properly)

  • Ad/cookie banner blocking (so our reports are clean)

This used to take a junior marketer 23 hours every week.

Now it runs in the background. Automatically.

No human needed.

H2: What About Other Tools?

I’ve tried a bunch.

  • Browser extensions: They crash on long pages or miss content loaded after scroll.

  • Puppeteer/Playwright: Powerful but complex. And not worth spinning up a full browser cluster for a screenshot.

  • Online screenshot tools: Most are limited. No full automation, poor quality, or watermark issues.

VeryPDF? It’s flexible, powerful, and stable. Doesn’t choke on edge cases.

Plus, their support is insane. I emailed a weird rendering bug and got a fix within hours. That kind of service is rare.

H2: Want to Try It?

I can’t recommend this enough.

If you’re tired of fiddling with screenshot tools, just try this:

Start using the API right now

You’ll be automating high-res screenshots like a boss in 10 minutes.

Seriously no more screenshot headaches.

H2: Need a Custom Version?

Maybe you’ve got a bigger setup.

Need to integrate screenshots into a CI/CD pipeline? Or build it into a desktop app? Or maybe you’re doing large-scale web monitoring?

VeryPDF’s dev team can help.

They offer custom development services for:

  • Windows, Linux, macOS, mobile platforms

  • C++, Python, PHP, JavaScript, C#, .NET

  • Virtual printer drivers that save print jobs as PDF, EMF, etc.

  • Hook layers to intercept system API calls

  • OCR, layout analysis, font management, and even barcode generation

  • Secure document conversion, encryption, digital signature tech

If you need a solution tailored to your stack or use case, reach out:
Contact their support team here

They’ve built crazy-specific solutions for serious clients they’ll do the same for you.

H2: FAQ

1. Can it block pop-ups and cookie banners automatically?

Yes. It uses a massive, constantly-updated rule set to block GDPR/cookie banners, chat pop-ups, and ads all with a simple flag.

2. Does it support mobile views and different screen sizes?

Absolutely. You can set predefined device sizes or custom screen dimensions for accurate mobile/desktop views.

3. Can I render pages that use JavaScript or lazy loading?

Yep. It waits for all content to load, scrolls the page, triggers lazy content, and even lets you run your own JS if needed.

4. What formats can I output to?

PNG, JPG, PDF, even MP4/GIF for scrollable captures. Pick what fits your workflow.

5. Is it hard to get started?

Not at all. You can make your first API call in minutes. SDKs and docs are super clear even for non-devs like me.

Take Mobile and Tablet Optimized Screenshots for Responsive Design Testing

Posted on

Take Mobile and Tablet Optimized Screenshots for Responsive Design Testing

Meta Description:

Stop wasting time with clunky browser toolsautomate mobile-friendly screenshots with VeryPDF Website Screenshot API for pixel-perfect responsive testing.

Take Mobile and Tablet Optimized Screenshots for Responsive Design Testing

Every time we launched a new webpage, we’d go through this painful checklist.

iPhone 14? Check.

Samsung Galaxy S21? Check.

iPad Air? Surface Pro? You name itwe tested on all of them manually.

And even with all that effort, half the time we’d still miss some weird layout issue on a niche device.

You know the kindtext cut off here, button misaligned there.

The worst part? It wasn’t because our devs were sloppy. It was just impossible to reliably test how a site would look across dozens of mobile and tablet viewportsunless we wanted to spend hours wrestling with emulators or physical devices.

That’s when I found VeryPDF Website Screenshot API for Developers.

And honestly, it’s been a game changer for how we do responsive design testing.

What Is VeryPDF Website Screenshot API?

It’s exactly what it sounds likea screenshot API that gives you pixel-perfect renders of any webpage across any device resolution you want.

All through a simple URL-based call. No clunky Chrome dev tools, no browser cluster nightmares, no clumsy mobile emulators.

Just pass in the URL, tell it the screen size or device you want, and boom: full, crisp screenshots in JPG, PNG, PDF, or even scrolling MP4/GIF formats.

This tool isn’t just for screenshots. It’s for automating what used to be a tedious, error-prone, manual process.

Who Is This API Built For?

If you’re a:

  • Web developer doing cross-device testing

  • UI/UX designer checking mobile layouts

  • QA engineer stuck validating dozens of viewport combinations

  • SaaS founder building a monitoring system for client sites

  • Agency running client reports on site presentation

then you’re gonna want this in your toolkit.

How I Use It in My Workflow

Let me break down exactly how I use VeryPDF’s API for mobile screenshot testing.

1. Set up my test URLs in a spreadsheet

I usually have 1520 core URLs per sitehomepage, product pages, checkout flow, login, dashboard, etc.

2. Define the key devices/screen sizes

Instead of testing “mobile,” I get specific:

  • iPhone SE (375×667)

  • Pixel 7 (412×915)

  • iPad Pro (1024×1366)

  • Surface Duo (540×720 dual screen)

3. Call the API for each combo

VeryPDF makes it ridiculously easy to generate a screenshot for each URL/device combination via a GET request.

bash
https://online.verypdf.com/api/?apikey=YOUR_KEY&app=html2image&infile=https://example.com&outfile=example_iphoneSE.png&--width=375&--height=667

And the output? Always razor-sharp.

What Makes This API So Useful?

Let me walk you through the three features I rely on the most.

1. Ad and Pop-Up Blocking

This blew my mind. You know how annoying cookie banners and chat widgets can be when you’re just trying to grab a clean screenshot?

This API automatically strips them out.

It taps into a rule database of 50,000+ banners, GDPR forms, and adsand just wipes them clean.

No more trying to manually hide selectors or write scripts to dismiss popups.

The API handles all that. You literally add one parameter to block them all.

2. Full-Page Lazy-Loaded Screenshots

Most screenshot tools choke on lazy-loaded content.

Not this one.

VeryPDF auto-scrolls through pages to trigger lazy-loaded images and AJAX-loaded content, so the final screenshot contains everythingno blank gaps, no missing sections.

This is crucial if your page relies heavily on client-side rendering.

3. Custom JavaScript and CSS Injection

Need to highlight a section, simulate a hover state, or hide a sticky header before capture?

No problem.

You can inject your own JS and CSS right in the request:

bash
--user-style="body { background: #fff; }"

--run-script="document.querySelector('.cookie-banner').remove();"

It’s like having full DOM controlwithout needing to fire up a browser.

Other Killer Uses

Here’s where I’ve used this tool beyond just responsive testing:

  • Automated daily screenshots for uptime/branding monitoring

  • Generate marketing images of SaaS dashboards for landing pages

  • Compliance reports that show “before and after” web changes

  • Scroll-recorded demo animations in MP4/GIF

  • Client deliverables in PDF, auto-captured at each release cycle

Basically, any time I want to show how a website looksat scale and without touching a browserI use this API.

How It Beats Other Screenshot Tools

I’ve tried most of the other tools in this space. And here’s where they fall short:

Feature VeryPDF Screenshot API Other Screenshot APIs
Blocks ads/popups
Full-page lazy-load rendering (only viewport)
Mobile & tablet presets (manual sizing)
JavaScript/CSS injection or overly complex
Scrolling screen recording

Plus, VeryPDF’s support is solid.

We hit a weird rendering issue once on an obscure device emulation.
Dmytro from their team patched it within hours.

That kind of support is rare in the dev tools world.

Why This API Replaced My Old Workflow

Before:

  • Screenshot manually in browser dev tools

  • Resize viewport

  • Dismiss popups

  • Capture

  • Save

  • Repeat 30x

After:

Final Thoughts

If you’re still manually capturing screenshots or relying on browser extensions to check mobile responsivenessplease stop.

You’re wasting time, and you’re missing stuff.

The VeryPDF Website Screenshot API does it better, faster, and cleaner.

It’s like hiring a virtual assistant who knows front-end QA and never takes a day off.

I’d highly recommend it to anyone doing responsive design testing, marketing asset generation, or automated UI QA.

FAQs

How do I use the API to test a mobile layout?

Just pass custom --width and --height parameters matching the mobile device screen size, and you’ll get a screenshot that mirrors the actual view.

Can I block specific elements like headers or banners?

Yes! Use the --hide-selectors option to target CSS selectors and hide them before the screenshot is taken.

Does it support dark mode screenshots?

Absolutely. You can force dark mode rendering using simple parameters. Great for testing light/dark theme switching.

What formats can I export to?

PNG, JPG, PDF, and even scrolling screen recordings as MP4 or animated GIFs.

Do I need to install anything?

Nope. It’s a cloud API. Just use HTTP requests with your API key. No local software needed.
