When to unlock a PDF
Your own files with passwords you keep typing, inherited documents with print restrictions, purchased material you're licensed to use but can't annotate. With the rightful password, unlocking is legitimate housekeeping.
Decryption is local — the password and file both stay on your machine.

Frequently asked questions
Can AmiPDF crack a password I don't know?
No. This tool removes protection using the correct password — it is not a cracker. If you've lost the password, no ethical tool can help.
Does it remove copy and print restrictions?
Yes. If you can supply the password, both the open password and the permission restrictions come off together.
Is unlocking a PDF legal?
When you have the right to the document — it's your file, or you're an authorized recipient with the password — yes. Don't use it on material you're not licensed to access.
Why do I get an error with the right password?
Check for typos and keyboard layout first. If the file uses an unusual encryption flavor, try re-saving it from a desktop reader once, then unlock that copy.
Is my password stored anywhere?
No. It's used in memory to decrypt and then discarded — nothing is transmitted or saved.
Can I unlock many files at once?
One at a time for now — each takes just seconds since everything runs locally.
