Watermark Image
Add text or a logo to JPG, PNG, and WebP images. Accepts JPG, PNG, or WebP up to 20 MB. Produces watermarked image. Processing happens locally in your browser.
Input: JPG, PNG, or WebP up to 20 MB · Output: watermarked image
Quality boundary
Text or logo watermarks are composited into a new local image. PNG and WebP transparency is preserved, but raster image watermarks cannot later be separated reliably.

Useful next actions
Add consistent text or logo watermarks to images.
Choose a corner mark for subtle attribution or a tiled mark for stronger reuse deterrence, then apply the same saved settings across a batch.
Match scale and contrast to the image
A logo should remain recognizable without becoming the subject of the image. Check it over both bright and dark areas, adjust opacity before size, and use a modest rotation for status labels. Nine-position controls make repeated placement predictable across images with different dimensions.
Preserve the right output format
JPG stays opaque and is suitable for photographs. PNG and WebP can preserve transparent areas, which matters for product graphics and overlays. The watermark is composited into the exported pixels, so keep the original image if you may need an unmarked version later.
