Watermark Eraser

Watermark Eraser does one specific thing: it removes the visible Gemini corner watermark from images you own, processing everything in your browser so no image upload is required. That local processing is the main trust signal — your images never leave your device. It is upfront about its limits too: it does not claim to remove SynthID or third-party watermarks, only the visible corner mark. It is free to use, which makes it an easy bookmark for cleaning up your own AI-generated images before publishing. Obviously it is a single-purpose utility, and anyone needing general object or watermark removal will need a fuller editor, but for its stated job it is quick and honest.
