Password Protect PDF Files
Encrypt PDF files before sharing contracts, reports, invoices, forms, and records. Protected documents require the correct password before the content can be opened.
Encrypt business documents with AES-256 password protection so sensitive contracts, reports, spreadsheets, presentations, and media files are not shared as ordinary open files.

GiliSoft PDF DOC Password Protect is designed for users who need to encrypt documents before they are shared, archived, or delivered outside a trusted workspace. It supports PDF, Word, Excel, PowerPoint, WPS, image, and MP4 files with AES-256 password protection.
Use it when a standard file attachment is too exposed, but a full DRM system is more control than the workflow requires. The goal is simple: create protected files that require a password before the recipient can open the content.

Different tools protect documents in different ways. This page is focused on password-protected file encryption for everyday document delivery.
| Tool or method | Best for | Important difference |
|---|---|---|
| PDF DOC Password Protect | Password-protecting PDF, Word, Excel, PowerPoint, WPS, image, and MP4 files with AES-256 encryption. | Best when multiple document types need one simple encrypted-delivery workflow. |
| PDF editors | Editing, annotating, merging, converting, and sometimes applying PDF-only password settings. | Useful for PDF workflows, but less focused on mixed document encryption. |
| ZIP or archive tools | Compressing files and applying archive-level passwords. | Convenient, but not a dedicated document-protection workflow. |
| PDF DRM Protection | Stronger document control, access rules, policy management, and post-delivery protection. | Better when you need more than password-based encryption. |
Use this workflow when documents should not be sent as ordinary open files.
