Watermark image
Stamp text (copyright) or a logo onto your image, place it and set opacity freely — right on your machine. Images never leave your machine.
The image watermark tool helps you protect your image copyright by adding a line of text (for example COPY, © your name) or a logo/stamp onto the image.
Drag the mark directly on the image to position it, and adjust its size, color, and opacity as you like. Everything happens right on your device — your images are never uploaded to a server.

Frequently asked questions
Does watermarking images send my images online?
Everything runs right in your browser — your files are never uploaded to any server, keeping them completely private.
Which logo format should I use for the watermark?
Use a PNG with a transparent background so the logo blends into the image best; JPG also works but will include the logo's rectangular background. You can adjust the opacity to make the mark more subtle.
Does this watermark provide absolute copy protection?
A visible watermark helps assert your copyright and deters casual reuse, but others can still crop or remove it if they try. For a harder-to-remove leak-tracing mark, see the invisible (forensic) watermark tool.
