PDF FixKit

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.
