Why use Image Watermark Tool?

This tool draws a text watermark directly onto your image using the canvas API, with a dark outline so the text stays visible against both light and dark backgrounds. Adjust the position, size, and opacity to balance visibility against how much of the underlying photo you want to keep clear.

Frequently asked questions

Can I add a logo image instead of text?

This version supports text watermarks only.

Will the watermark be removable?

The watermark is baked into the image pixels, so it can't be removed without image-editing software — unlike a watermark added as a separate overlay layer.

Is my image uploaded anywhere?

No. The watermark is applied entirely in your browser.
