Protect and brand your images with a text or logo watermark. Control opacity, rotation, size and position (nine anchor points or a repeating tile), preview live, and apply to a whole batch with a ZIP download — all in your browser. Add Watermark is a free, browser-based tool in the Toolsnest image tools collection — there is nothing to install, no account to create and no watermark on your results. It works on desktop, tablet and mobile, and because the work happens on your own device it stays fast even with large inputs.

Frequently asked questions
Can I use my own logo as a watermark?
Yes. Switch to ‘Image / logo watermark’ and upload a PNG (transparency is preserved). Adjust its size, opacity, rotation and position.
How do I watermark many images at once?
Add all your images, configure the watermark once, and apply it to the whole batch. Download everything as a ZIP.
Can I tile the watermark across the image?
Yes. Enable ‘Tile across image’ to repeat the watermark on a rotated grid — useful for strong copyright protection on previews.
Are my images uploaded?
No. Watermarking is done locally on a canvas in your browser; nothing is sent to a server.
