Frequently Asked Questions
How does Unlock PDF work?
Upload a password-protected PDF and enter its password. We verify the password, decrypt the file, and give you back an identical PDF that opens without any password.
Do I need to know the password?
Yes. To unlock a PDF that requires a password to open, you must provide that password — this tool removes protection you are authorised to remove, it does not crack or bypass unknown passwords.
What if the PDF only restricts editing or printing?
Some PDFs open freely but block editing, copying, or printing with an owner password. Leave the password field blank and we will remove those restrictions for you.
Is uploading my password safe?
Yes. Your password is used once in memory to decrypt the file and is never stored or logged. The connection is encrypted, and both the file and password are discarded after processing.
How long are my files kept?
Files are processed on secure servers and automatically deleted within 1 hour. We never store or share your documents.
Is it free?
Yes, with daily limits. Free and guest outputs include a watermark; upgrade to Pro for clean, watermark-free output and higher limits.
