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
- Open this page and add the photo you want to watermark.
- Type the watermark text and adjust its size, color and opacity.
- Choose a corner, center or tiled placement — tiled covers the whole image.
- Download the PNG; the original photo never left your device.
When this helps
- Tiling a faint watermark across ID cards or passports you must send to someone.
- Marking draft designs as samples before sharing them with clients.
- Adding your handle to photos before posting them publicly.
- Labeling confidential screenshots for a specific recipient or purpose.
Limits and notes
- Only text watermarks are supported, not image logos.
- A watermark deters casual reuse; a determined editor can still remove it.
- Download the result before closing the tab — nothing is stored.
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 Original photos stay on your device — ideal for client work and unpublished designs.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.
