UndoPDF, Inc. offers the most complete range of options to recover
Adobe Acrobat (.pdf) passwords.
A PDF document can have two kinds of passwords: a Document Open
password and a Permissions password. When you set a Document Open
password (also known as a user password), anyone who tries to open
the PDF document must type in the password you specify.
When you set a Permissions password (also known as a master password
or 'owner' password), only those people who have typed the
Permissions password can change security settings. If the PDF
document has both types of passwords, it can be opened with either
password, but a user can set or change the restricted features only
with the Permissions password. If the PDF document has only the
Permissions password, or if the user opens the document using the
Document Open password, the password prompt appears when the user
tries to change security settings.
If your PDF file has 'owner' password and without 'user' password,
you can simple use our PDF Password Cracker product to remove the security from
your PDF file, then you can copy, print and edit your PDF file
without any restrictions -- i.e. with edit/copy/print/annotate
If your PDF file has 'user' password, you can use our PDF Password
product to brute-force attack your PDF file. However, we can provide
PDF password recovery service for you, our services will recover the
User Password, then you can use this User Password to open your PDF
