Frequently asked questions
Do I need to know the password?
Yes. This tool removes a password from a PDF you can already open — you must enter the correct password. It is not a password cracker.
Is the oMyPDF unlock tool free?
Yes. Removing a known password is 100% free with no sign-up required.
The PDF has both an open password and an owner password — which do I enter?
Either one. If a PDF has a separate owner (permissions) password as well as the open (user) password, entering either password will fully unlock it. The output has no password and no restrictions.
Will the unlocked PDF ask for a password again?
No. The output is fully decrypted, so it opens without any prompt in Chrome, Adobe Acrobat and other viewers.
Is it legal to unlock a PDF?
Only unlock PDFs you own or have permission to modify. Removing protection from documents you don't have rights to may be illegal.
Are my files safe?
PDFs under 15 MB are unlocked entirely in your browser — your password and file never leave your device. Larger files are sent over an encrypted connection, processed immediately, and deleted right after.
