PDF password
Set or remove a PDF password right on your machine. Neither the file nor the password ever leaves your machine.
Everything happens on your machine — neither the file nor the password is uploaded to any server
Adding a password to a PDF protects sensitive documents — contracts, payroll slips, personal records — so only someone with the password can open them; the tool can also remove a password once you know the current one.
The key difference: both the file and the password are processed entirely in your browser on your own device, and nothing is ever sent anywhere. That lets you lock or unlock PDFs with complete security, for free, and with no software to install.

Frequently asked questions
Is the password I enter sent anywhere?
Everything runs right in your browser — your files are never uploaded to any server, keeping them completely private. Passwords are used only locally in the browser.
If I forgot my PDF's password, can I still remove it?
No. To remove a password you must enter the correct current password — this is a security requirement, and the tool does not crack passwords.
Is the file completely clean after the password is removed?
Yes. The tool rebuilds a new file with no remaining encryption data, so it opens in any PDF reader.
