Frequently Asked Questions
Can I unlock a PDF without its password?
No. This tool does not crack passwords. A file with an opening password requires the correct password.
Can I unlock a PDF that opens freely but prohibits printing or copying?
Yes. The tool detects permission restrictions and creates an unrestricted copy without an opening password. Only files with neither an opening password nor permission restrictions are reported as not needing unlocking.
What if the password is correct but the file still fails?
Check case, spaces and the password source, then test the original elsewhere. Damage or unsupported encryption can prevent processing; no brute-force cracking is performed.
Is unlocking the same as removing a certificate signature?
No. Unlocking removes opening passwords and permission restrictions, not certificate signatures. Rewriting the file can still affect signatures; keep the original.
Does unlocking modify my original file?
No. The original stays unchanged. The downloaded copy has its opening password and permission restrictions removed.
