FAQ
Can I unlock without the password?+
PDFs with only edit/print/copy restrictions (owner password) can sometimes be bypassed, but user passwords that block opening require the actual password.
Does it support brute-force cracking?+
No. This tool doesn't crack passwords. It's intended for legitimate unlocking of PDFs you own.
What about AES-256 strong encryption?+
The pdf-lib library has limits, so some strong encryption can't be processed. Use Hancom Office or Adobe Acrobat's built-in unlock feature for those.
Is this legal?+
Only process files you own or have a legitimate right to unlock. Unlocking someone else's PDF without permission may violate copyright or computer access laws — responsibility rests with the user.
Is the original file modified?+
No. The original stays intact and only a new unlocked copy is downloaded.
Is the file sent to a server?+
Everything is processed in your browser — neither the PDF nor the password is transmitted.
