What Watermark Pro is
Watermark Pro is a free browser-based tool for adding text or logo watermarks to batches of photos. It can process hundreds of images at once, and processing happens locally in the browser rather than uploading photos to a server. The editor provides text and logo layers, with controls for opacity, rotation, tiling, fonts, colors, and scaling. Save preferred settings as presets, then export processed images together in a ZIP file. A local activity log keeps track of exports and settings. The maker describes the project as open source and free for everyone; its README identifies the MIT License. The tool is designed for photographers and content creators. It runs in a web browser, with Chrome, Edge, Firefox, and Safari listed as supported modern browsers. The Free plan costs nothing.
