Can't open a password-protected PDF? Our professional service recovers the password so you can remove the encryption permanently. Works with all PDF versions and encryption types.
A PDF can have either an open password or permission restrictions. Uploading the file identifies which applies and shows the correct next step.
Recovery process
Upload the PDF you can't open. We automatically detect the encryption type (RC4 or AES) and estimate how long removal will take.
Our powerful servers run millions of password combinations per second using dictionary attacks, brute force, and intelligent pattern matching to recover the password.
Once found, you receive the password via email. Open your PDF and save it without protection. You only pay if we find your password. Simple PINs (up to 4 digits) and top 10K common passwords are FREE if found during Fast Check.
