Password protect a PDF
Add an open password to a PDF, without uploading it.
A password on a PDF means only someone who knows it can open the document. The catch with most online tools is that you upload the very file you are trying to protect. Here the password is applied in your browser, so neither the file nor the password is ever sent to a server.
How to password protect a PDF
- 1
Add your PDF
Drop in the document you want to protect.
- 2
Set a password
Choose a strong password that will be needed to open the file.
- 3
Encrypt and download
Save the protected PDF, encrypted on your device.
Why add the password on your device
Uploading a document to a website just to password-protect it hands over the unprotected file first. Encrypting locally means the open version never leaves your computer and the password is never transmitted.
Frequently asked questions
Do you see my password or file?+
No. The encryption runs in your browser, so your password and document are never uploaded, logged or stored.
What encryption is used?+
Standard AES encryption, applied locally, the same scheme used across the PDF industry.
What if I forget the password?+
It cannot be recovered. Because nothing is uploaded, there is no copy anywhere, so keep the password safe.
Is it free?+
Yes, with no sign-up.
