Password protect a PDF online — free
The free Protect PDF tool adds password encryption to a PDF so only people with the password can open it. Upload your document, set a strong password, and download the encrypted file — a free account and no watermark added.
Keep sensitive documents locked
Use it for contracts, financial statements, medical records and any file you send by email or share in the cloud. Choose a strong, unique password and send it to recipients through a separate channel — the password cannot be recovered if it is lost.
Secure and private
Uploads use 256-bit SSL encryption and files are automatically deleted from our servers after processing. We never store your password or your document.
