Add Watermark to Image
Add a text watermark to a photo without installing anything or creating an account.
Pick one of eight fixed positions or tile the text diagonally across the whole image for stronger copy protection.
Key features
- Renders and edits the image on an HTML5 canvas directly in the browser.
- Opens a local file in the browser without uploading it to a server.
- Adjustable controls for watermark size, opacity, and position.
- Exports the result as a downloadable blob with no server round-trip.
- Builds the output object URL entirely client-side, ready for instant download.
When to use it
Stamp a name or brand across product shots, mark draft photos before you share them, or label screenshots you post online. Because the tool opens the file locally and never sends it anywhere, it suits sensitive images you would rather not hand to a web service.
Privacy and data handling
Everything runs locally via canvas - the photo is never uploaded. The tool creates and mounts a canvas in your browser for rendering, and the finished image is built as a client-side object URL, so nothing leaves your device.
