About This Feature

Overview

Document Encryption is a document security feature in WPS Office for Windows. It helps protect document content from unauthorized viewing or editing. It supports both account-based encryption and password encryption, and lets you set separate passwords for opening a file and modifying a file.

Core capabilities include:

Password encryption for open and edit control.
Removing password encryption when the original password is known.
Handling account-encrypted documents by signing in with the related account.
Reviewing encryption types and content protection options, including content paste protection.

This feature is useful for contracts, proposals, internal files, and personal documents that need controlled access. After protection is enabled, it can reduce the risk of casual viewing, copying, or editing.

Compare with Alternatives

Dimension	WPS	Microsoft	Google	Notion	Adobe
Capability Summary	Supports account-based encryption and password encryption, with separate passwords for opening and modifying a file, plus related content protection options.	Word supports password protection for documents and lets users remove an existing password; it also provides document protection and editing restriction options.	Google Docs focuses on permissions and default encryption for cloud collaboration; some client-side encryption features depend on specific Google Workspace editions rather than a local document password flow.	Notion mainly uses page locks, sharing controls, and permission levels to manage access and editing, rather than password-encrypting a single document file.	Acrobat supports password protection and permission controls for PDF files, including restricting opening or editing.
WPS Advantages	Advantage: WPS combines account-based encryption, password encryption, separate open/edit passwords, and content protection in one document workflow for Windows office files.	Compared with WPS: Word has clear password protection steps, but its protection flow is centered on Word document protection rather than the same mix of account-based encryption and content paste protection described here.	Compared with WPS: Google Docs is stronger in cloud permission management and collaboration, while direct password setup for a local document is less central than in WPS.	Compared with WPS: Notion is better aligned with collaborative access control and page locking, not direct password encryption for a document file.	Compared with WPS: Adobe has clear PDF security workflows, but its protection focus is PDF-based rather than editable office documents in the same writing environment.

Overall Conclusion: If you want to password-protect or manage access to everyday editable documents on Windows, WPS Document Encryption provides a direct workflow inside the document editor. Google Docs and Notion are more centered on cloud permissions and collaboration, while Adobe Acrobat is more focused on PDF protection.
