Text or logo watermarks, entirely in the browser
This tool stamps a watermark onto your image directly in your browser. Type a name or copyright line, or upload a logo, ideally a PNG with transparency, then place it with the nine-position grid, scale it, set the opacity, and rotate it if you like. The preview updates live as you adjust, so what you download is exactly what you saw.
The tiled mode repeats the watermark diagonally across the entire image, the way stock photo sites do. A single corner mark is easy to crop away; a tiled one is not, which makes it the right choice when you are sharing proofs or previews you do not want reused.
Because everything runs on your device, there is no upload, no queue, and no limit. Watermark one photo or a thousand; the only cost is your own CPU time.
Watermarking well: a few practical rules
Opacity around 50 to 70 percent marks the image clearly without ruining it; full opacity is rarely needed. Size the mark so it cannot be cropped without losing the subject: for portfolio shots, a corner mark near the subject works, and for client proofs the tiled mode is safer. White text survives most photos; switch to a dark color on bright skies and snow. And keep your original unwatermarked file, the watermark here is baked into the pixels of the copy you download.
Going the other direction? Our free AI watermark remover erases watermarks from images you have the rights to edit, and is the honest mirror of this page.
What to expect
The output keeps your image's format and full resolution: PNG stays PNG with transparency intact, JPG stays JPG at high quality. The tool accepts JPG, PNG, WebP, AVIF, GIF, BMP, and HEIC. For preparing images before watermarking, the free image resizer and free image compressor run in the browser too, so the whole pipeline stays on your device.
