Tentang Alat Ini
Timestamp PDF adds a local timestamp certificate to your PDF documents, creating a self-signed proof that a document existed at a specific point in time.
The timestamp is generated locally in your browser using a self-signed certificate. This is not an RFC 3161 trusted timestamp from a certificate authority — it serves as a personal record of when the document was processed.
All processing happens entirely in your browser. Your documents never leave your device.
