How this tool works
What it does
Watermark Image overlays a text or logo watermark, single or tiled.
Type
Text (with size/colour) or logo image (second box).
Output
PNG/JPG/WebP; optional target KB.
Privacy & metadata
Everything runs in your browser on a canvas — your image is never uploaded. Browser canvas export strips EXIF, GPS, and most other source metadata.
Watermark Image in your browser
Watermark Image adds a text or image watermark to a photo in your browser. Everything runs in your browser on a canvas — your image is never uploaded. Choose text or a logo image, set the opacity, position (including a repeating tile), rotation and size, and export as PNG, JPG, or WebP.
Text watermarks need nothing extra; image watermarks use the second upload box for your logo. PNG/WebP output keeps the photo’s transparency; JPG is flattened. You can also target a maximum file size in KB.
Watermark Image shows the watermark settings, the output format, the file size and (if used) whether it met the target size. Browser canvas export strips EXIF, GPS, and most other source metadata. Animated GIFs are processed as a single still frame; animation is not preserved.
