About this tool

Gemini Watermark Remover is a free, privacy-first web tool for removing visible watermarks from Gemini AI-generated images. It uses reverse alpha blending and processes JPG, PNG, and WebP files entirely in the browser, so images never leave the user’s device. It supports single and batch processing, ZIP downloads, mobile and desktop use, and multiple interface languages. No signup or upload is required. The tool removes visible watermarks only and does not remove invisible SynthID watermarks.
