What ToolMole Batch Add Watermark is

ToolMole Batch Add Watermark is a free browser tool for applying text or logo watermarks to groups of photos. It accepts JPG, PNG, and WebP images, while logo files may be PNG, SVG, WebP, or JPG. Users can set position, size, opacity, and text color, with an optional shadow for text marks. Watermark size is defined as a percentage of image width, helping it scale across differently sized files. A tiled angled option is available for proofs and previews and is intended to remain visible after cropping or screenshotting. Processed files retain their format and filename, with “-watermarked” appended, and can be downloaded individually or as a ZIP. Images are processed in the browser on the user’s machine rather than uploaded. After the first visit, the tool works offline. There is no fixed image-count limit, but files are handled one at a time. PNG output is lossless; JPG and WebP are re-encoded at high quality with some generational loss.
