Password protect PDF
Add or remove a PDF password in your browser — protect with 256-bit encryption, or remove a password you know. No upload, no signup.
Protect a PDF with a password using 256-bit encryption, or remove a password from a PDF when you know the current one — without uploading the file. Adding a password keeps anyone from opening the document without it; removing one is useful once a file no longer needs securing. Everything runs in your browser, so the file and the password never leave your device. Free, no account, no watermark.
How it works
- Open a PDF from your device
- Add a password, or remove one you know
- Download the protected or unlocked PDF
