Up to 10 PDFs — each gets the same password
Most online PDF encryption tools force a trade-off: upload your file to a stranger's server, cap the number of pages, or hide real controls behind a paid plan. Ours does none of that. Drop up to ten PDFs, pick a password, optionally restrict printing / copying / editing — and save AES-encrypted copies.
Encryption happens in your browser. Your files and your password never leave your device — no server ever sees them. Safe for sensitive documents — contracts, financial statements, medical records — where sending data to a third-party service is not an option. No installation, no account, no daily limits.
Forgot a password you set earlier? We cannot recover it — by design there is no backdoor. If you need to remove a password from a PDF you already know the password for, use the Unlock PDF tool instead.
Yes — free, no account, no watermarks.
No. Password protection is applied entirely in your browser. Your PDF never leaves your device.
The tool applies AES encryption to protect your PDF with the password you set.
Yes. Upload any PDF, enter a password, and download the protected file.
The password cannot be recovered. Make sure to store it safely — without it, the PDF cannot be opened.
