What to write in the watermark
Use specific purpose text such as “For XX verification only”, “For XX bank account opening only” or “For this application only”. Specific text is more useful than generic anti-copy wording.
How the watermark should look
A semi-transparent diagonal watermark repeated across the image usually works well. It should be visible, but it should not block fields that the receiving platform needs to read.
Why local processing matters
ID photos and document scans often contain personal details. Local browser processing avoids uploading the original image to a separate watermarking service.
When to use it
Use it before identity verification, certificate submissions, rental applications, HR onboarding, contracts and business document uploads.
FAQ
Does a watermark guarantee that my ID cannot be misused?
No. It reduces risk and clarifies purpose, but it does not replace careful document handling.
