Free image watermark tool. Add a text watermark with adjustable size, opacity, colour and position, or tile it across the image, then download, no signup, runs locally.
Add a text watermark to any image with control over size, opacity, colour and position, or tile it diagonally across the whole photo, then download the result.
A watermark deters unauthorised reuse and keeps your brand on every share. Add your name, handle or copyright over any photo, then fine-tune the size, opacity and colour so it's visible without ruining the image. Choose a corner, the centre, or tile it diagonally for maximum coverage.

There's no account and no upload, the watermark is drawn on a canvas in your browser, so your photos stay private, even sensitive ones. Preview updates live as you adjust the controls, and you download a clean PNG when it looks right.
A small watermark in a corner is easy to crop out in seconds. If your goal is to discourage reuse, place the mark over part of the subject or use the tiled mode, which repeats it across the whole image so no single crop removes it. Opacity between 20% and 40% keeps the photo viewable while still making the mark obvious. If your goal is branding rather than protection, a clean corner mark at higher opacity reads better. Either way, watermarking only deters casual copying: it won't stop a determined editor, so for important work also keep your original high-resolution files and publish smaller versions online.
The watermark is drawn onto the image at its full original resolution, so export size matches your upload. Download as PNG when the image has sharp text, graphics or transparency, and as JPG for photographs where a smaller file matters more than perfect edges. Pick a watermark colour that contrasts with the area it sits on: white text with a slight shadow works on dark photos, and dark text works on bright skies or product shots on white. Because everything runs in your browser, you can watermark client work or unpublished photos without uploading them anywhere.
