Add a Watermark Without Uploading

Stamp a text watermark onto photos without sending them anywhere. Everything runs in your browser — essential when the image is an ID card or a confidential document.

How it works

  1. Open this page and add the photo you want to watermark.
  2. Type the watermark text and adjust its size, color and opacity.
  3. Choose a corner, center or tiled placement — tiled covers the whole image.
  4. Download the PNG; the original photo never left your device.

When this helps

Limits and notes

Watermarking ID photos safely

A watermark only protects you if adding it does not leak the document first. Uploading an ID card to a random website defeats the purpose. On this page the photo is read straight into your browser, stamped and downloaded — the image data never crosses the network.

What you can do next

FAQ

Is my image uploaded?

No. The watermark is drawn on a local Canvas. Original photos stay on your device — ideal for client work and unpublished designs.

Corner mark or tiled — which should I use?

A small corner mark credits you without distracting; tiled mode makes the image hard to steal or reuse — best for proofs and previews.

What opacity works best?

30–50% for tiled watermarks (visible but doesn't ruin the image), 60–80% for a corner signature.
