Effective watermarks

A semi-transparent watermark (30–50% opacity) across the middle or tiled over the image is much harder to crop out than a small corner mark, while still letting viewers see the photo.

Limitations

Text watermarks only (no logo images yet).

Privacy

Files you choose are read into your browser’s memory and processed on your device; they are not uploaded to a server. Temporary download links are released after use, and the offline cache never stores your documents. More about privacy and limits.

Frequently asked questions

Can I watermark many photos at once?

Yes, all selected images get the same watermark, scaled to each image’s size.

Are my images uploaded?

No. The conversion runs in your browser using WebAssembly versions of the same codecs desktop apps use. Your photos never leave your device.

Is it free?

Yes – free with no signup, no watermark and no daily limit. You can process many images at once.
