Protect PDF
Add a password to a PDF so only people you share it with can open it. Drop your file, choose a password, and download the protected, encrypted PDF.
Anyone opening the PDF will need this password. Keep it somewhere safe — it can't be recovered.

Frequently asked questions
How strong is the protection?
Your PDF is encrypted with 256-bit AES — the same standard used to secure sensitive documents. Without the password, it can't be opened.
What if I forget the password?
We can't recover it — that's the point of encryption. Store your password somewhere safe before sharing the file.
Is protecting a PDF free?
Yes — free with no account. Daily limits apply to keep the service fast for everyone.
What happens to my file and password?
Your file is deleted from our servers automatically within 2 hours, and your password is used only to encrypt it — never stored or shared.
