PicSeal

什么是 PicSeal？

PicSeal lets you seal only the sensitive text and images inside PDF, DOCX, and HWP/HWPX files without converting editable documents to PDF. Public content stays visible, while authorized users can unseal and restore the original content for further editing. COXSI document classification and security policies improve sensitive-content detection. Access conditions, audit records, Google Drive integration, and PicSeal Reader support secure distribution.
