Frequently asked questions
Can OmniPDF crack a PDF password?
No. Only known passwords can be used to unlock a PDF. There is no password guessing.
Is it legal to unlock a PDF?
Only for PDFs you own or have explicit permission to modify. Do not use this tool on documents you are not authorized to edit.
Does unlocking break digital signatures?
Yes. Decrypting rewrites the file bytes, so any existing signature is invalidated.
