Fonctionnement
How does this tool work?
The PDF security engine loads the document only in the browser and applies AES-256 encryption with the password you choose. The downloaded file then requires that password when opened in a compatible PDF reader. The source document stays unchanged. This PDF-to-PDF transformation is also available in Workspace, so a pipeline can finish with password protection after sanitizing, compression, page numbering or watermarking.
