Add an open password with AES-256 encryption to your PDF — right in your browser, without uploading the document to any server.
One PDF file. You can also drag it here.
Keep the password somewhere safe: since nothing leaves your device, nobody can recover it if you forget it — not even us.
Just one document. It never even leaves your device.
Type and confirm the password that will protect it from opening.
The downloaded PDF only opens with the password you set.
Need to email a contract, a payslip or a medical record and want to make sure only whoever has the password can open it? Protect PDF applies an open password with AES-256 encryption — the strong standard for PDF protection. Unlike sites that upload your file to the cloud, here protection happens in your browser: the document and the password never leave your device, which matters exactly when the paperwork is sensitive. One important reminder: since we don't store anything, write the password down — without it, neither you nor we can open the file afterward.
Upload the PDF, type the password you want (and confirm it), and click Protect PDF. The downloaded file only opens with that password. Everything happens in your browser.
256-bit AES encryption is used, the strong standard for PDF. The password protects the document from being opened.
No. We don't store anything — not the file, not the password. Write the password down somewhere safe, because without it nobody can open the PDF (not even us).
No. Protection happens entirely in your browser. The PDF and the password never leave your device.
