How PDF Password Protection Works
PDF password protection encrypts your document so that only people with the correct password can open and view it. This is essential for sensitive documents like financial reports, legal contracts, and personal records.
There are two types of PDF passwords: a user password (required to open the document) and an owner password (controls permissions like printing and editing). Our tool applies a user password to restrict access entirely.
Your files are processed entirely in your browser. No data is uploaded to any server, ensuring complete privacy and security for your sensitive documents.
