Flatten and protect the document
Add password protection to any PDF document. When you set a password, recipients must enter it before they can open or view the file. This is the simplest way to restrict access to sensitive documents — financial reports, legal contracts, medical records — before sharing them via email or cloud storage.
Password Encryption
Encrypts the PDF so it can only be opened with the correct password.
Easy to Use
Just upload, type a password, and download. No complicated permission settings to configure.
Universal Compatibility
The protected PDF opens in any standard PDF viewer — Adobe Reader, browser viewers, Preview, and more.
Client-Side Encryption
Your document and password are processed locally in the browser. Nothing is sent to a server.
