Add a watermark to images
Protect your images with a text or logo watermark. Drag it into place, tune size, rotation and opacity, and export — one image or a whole batch, all in your browser.
Privacy-first: every image is processed locally in your browser. Nothing is uploaded, stored or transmitted to any server.
What a watermark actually buys you
A watermark won’t stop a determined thief, but it does three real jobs: it keeps attribution attached as an image travels (screenshots included), it turns casual reuse into free advertising, and it marks proofs and drafts as not-final. The craft is in marking the image without ruining it.
Text or logo, subtle or tiled
Use a text mark (name, ©, handle) or upload a logo; place it in a corner at modest opacity for portfolio work, or tile it across the full image for proofs and previews. Size, position, rotation and transparency are all adjustable with a live preview — and batch mode marks an entire delivery identically. Local processing, as always.
Frequently asked questions
- Are my images uploaded to add the watermark?
- No. The watermark is drawn onto your image locally using your browser’s canvas. Nothing is sent to a server.
- Can I watermark many photos at once?
- Yes. Drop in any number of images and the same watermark settings are applied to all of them. Download results individually or as a single ZIP.
- Can I use my own logo as the watermark?
- Yes. Upload a PNG, JPG, WebP or SVG logo. Transparent areas are preserved, and you can control its size, opacity and rotation.
- How do I position the watermark?
- Use the nine placement presets (corners, edges, center) with an adjustable margin, or simply drag the watermark on the live preview and pull its handles to resize and rotate.
- Can I tile a repeating watermark across the whole image?
- Yes. Switch placement to “Tiled / repeat” and the text or logo repeats diagonally across the entire photo, like the watermarks stock-photo sites use. You can adjust the angle, the spacing between repeats and the size.
- Is the watermark permanent?
- Yes. The watermark is baked into the exported image’s pixels, so it cannot be removed from the downloaded file.
