Gemini Image Cleaner - Watermark Remover & Batch Image Downloader

Remove visible Gemini and Nano Banana image watermarks locally. Download clean images individually or in batches without uploads.

Gemini Image Cleaner is a private Gemini watermark remover and batch image downloader for images you are authorized to use. It processes visible corner marks locally in your browser, keeps image quality under your control, and never uploads your images. Use it when you need to: • remove a visible mark from a Gemini or Nano Banana image • download one clean image without extra steps • batch process a conversation gallery and save every result as a ZIP • export PNG, WebP, or JPEG with your preferred quality and filename • keep prompts, conversations, and image files on your device How it works: 1. Open a supported Gemini or Google AI Studio page. 2. Choose the latest image or scan the visible gallery. 3. Clean and download one image, or process the whole batch. 4. Save the results individually or in a tidy ZIP archive. Privacy and provenance: Image processing happens on your device. The extension does not upload images, prompts, or conversation text. It only processes visible marks and does not remove or circumvent invisible provenance signals such as SynthID. Gemini Image Cleaner is useful for designers, marketers, creators, students, and anyone who regularly saves authorized AI-generated images from Gemini or Nano Banana.
