Upload a PDF, pay once for that file, receive a technical verification certificate and a subtle seal watermark on every page. No customer account is required.
Seal of Approval provides technical document verification based on file hashes, timestamps and verification IDs. It does not replace a qualified electronic signature or certified trust service.
