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.
