Frequently asked questions
What is the ID watermark tool?
Adding a watermark such as “for [bank] account opening only, invalid for other uses” across a copy of your ID card, driver license or passport is the simplest way to stop it being reused for fraud. This free tool tiles your watermark text diagonally across the whole image so it can’t be cropped out — and because everything runs in your browser on an HTML canvas, your sensitive documents are never uploaded to any server.
How to watermark an ID or document copy
- 1
Upload your image
Drop in a photo or scan of your ID card, driver license, passport or document. It stays in your browser — nothing is uploaded.
- 2
Add the watermark
Type your own text or pick a preset like “for bank account opening only, invalid otherwise”, then tune opacity, angle and colour. Optionally black-box or pixelate sensitive fields.

Download
Save the watermarked image at full resolution — generated entirely on your device, free and with no sign-up.
Are my documents uploaded to a server?
No. The whole tool runs in your browser using an HTML canvas. Your image is read locally and the watermarked result is generated and downloaded on your device — nothing is ever sent to cv.cm or anywhere else.
What should the watermark text say?
State the specific purpose and that other uses are invalid, e.g. “for [bank] account opening only, invalid for other uses”. Place it so it partly overlaps the photo and key fields so it can’t be cropped away.
Is it free?
Yes, completely free with no sign-up and no limits. You can watermark as many ID, license or document copies as you like.
