About Watermark Images
How it works
Apply one watermark consistently across a batch. Watermark width is relative to each image, so different image sizes do not need separate settings. Text uses white lettering with a dark outline. Transparent PNG logos work well for branding.
Supported files and practical limits
JPG, PNG and WebP input; up to 20 images, 20 MB and 25 megapixels each, 100 MB combined. Outputs are flattened still images without original metadata. Watermarking discourages casual reuse but does not prevent copying.
Common uses for Watermark Images
