StampThat Nicolas Micaux توسط

StampThat automatically watermarks your documents the moment you upload them—anywhere on the web: email, Google Drive, WhatsApp Web, administration portals, bank forms, and more.

A watermarked ID or contract cannot be reused to take out loans or commit fraud. With StampThat, your documents stay usable for their purpose, but worthless to hackers.
