About This Feature
Overview
WPS PDF Validate Signature is a PDF feature in WPS Office that helps verify digital signatures in signed PDF files. It lets you check whether a signature is valid, whether the document was changed after signing, and what certificate details are attached to the signature.
This WPS PDF workflow supports three main tasks:
- Validate all signatures in a PDF document after the file is opened.
- View signature details, including the signer, signing time, certificate information, and validity result.
- Open the detailed validation result from the status bar to review document integrity.
It is useful for contract review, archived file checks, and document verification during cross-team approval processes.
