How it works
Choose the protected PDF.
Type its password, or leave it empty if the PDF opens without one but blocks printing or copying.
Download the unlocked copy: it opens with no password.
Why GenPDF
The PDF is unlocked in your browser: neither the file nor its password is uploaded.
A PDF that opens but won't let you print or copy is freed as well, without a password to type.
The unlocked copy can then be merged, edited, signed or compressed like any other PDF.
