Protecting Your Images Without Ruining Them

If you share photos online — whether you're a photographer, designer, or sell products — watermarking is the simplest way to prevent unauthorized use. A subtle semi-transparent watermark discourages theft without destroying the viewing experience. The key is getting the opacity right: visible enough to deter copying, light enough that the image still looks good.

Most watermarking tools require you to upload your photos to their servers. That's a privacy and security concern, especially for unpublished work or client photos. This tool runs entirely in your browser — your images never leave your device. The watermark is applied locally using Canvas API, then you download the result.

Frequently Asked Questions

Can someone remove the watermark?

A well-placed watermark over important parts of the image is very difficult to remove cleanly. Center-positioned watermarks that overlap the subject are hardest to strip. Edge-only watermarks can be cropped out, so position matters.

What opacity should I use?

30-40% opacity is the sweet spot for most uses. It's clearly visible as a mark of ownership but doesn't overpower the image. For stronger protection, 50-60% makes removal much harder at the cost of aesthetics.

Can I watermark multiple photos at once?

Yes. The tool supports batch processing — drop multiple files and the same watermark settings apply to all of them. Free tier allows up to 50 files per day.
