About This Tool

Why Password-Protect Your PDF? The Complete Guide

Adding password protection to a PDF prevents unauthorized access to sensitive documents such as financial reports, legal contracts, medical records, personal identification, and confidential business information. PeachPDF uses industry-standard 256-bit AES encryption — the same standard used by banks and government agencies.

You can set an open password that recipients must enter to view the document, and optionally set permissions that control whether the document can be printed, copied or edited. This dual-password system gives you complete control over how your PDF can be accessed and used. The encryption is applied instantly and your protected PDF is ready to download in seconds.
