It works directly in your browser and integrates with Gemini preview images, copy actions, and download actions. When a supported Gemini image is detected, the extension processes the image locally and returns a cleaned version without adding extra buttons to the Gemini interface. Key features: - Automatically processes supported Gemini-generated images. - Works with preview images, copy image, and download image flows. - Includes a popup toggle so you can disable the extension if Gemini becomes slow or behaves unexpectedly. - Processes image data locally in the browser. - Does not collect accounts, prompts, chats, or personal data. This extension is designed for Gemini's visible watermark format. It does not remove invisible or steganographic watermarks, and it may not work if Gemini changes its image delivery or watermark format.

Gemini Watermark Remover
Remove Gemini Watermark efficiently with this Gemini Watermark Remover. Restores pixels locally using alpha-reversal. Restore your AI-generated artwork to its pristine state by mathematically removing the visible Gemini watermark. Unlike standard retouching tools that blur or crop, this extension calculates the original pixel values hidden beneath the semi-transparent logo overlay. Smart Pixel Restoration: Automatically detects watermark resolution and uses alpha-channel reversal to recover original image details. Privacy-First Architecture: All processing occurs locally within your browser via HTML5 Canvas. No images are ever uploaded to any server. Lossless Quality: Maintains the original image resolution and exports as high-quality PNG. Efficient Workflow: Supports drag-and-drop and clipboard pasting for quick interactions. Disclaimer This independent open-source project is not affiliated with Google LLC. This tool is designed to remove visible visual overlays only and does not affect invisible metadata or digital signatures such as SynthID.
Gemini Watermark Remover - Banana Clean
Remove the Gemini watermark on download. Converts to WebP/JPEG, auto-renames files. Pixel-perfect, 100% local, under 100ms. Banana Clean removes the Gemini watermark from AI-generated images as you download them. It also converts images to WebP or JPEG — cutting file size by 75% — and auto-renames files to clean, dated names. Features that other watermark removers don't offer. How it works: 1. Generate an image on gemini.google.com or Google AI Studio. 2. Click the download button. 3. The extension intercepts the file, removes the Nano Banana sparkle logo using reverse alpha blending, converts to your chosen format, and renames the file. All in under 100 milliseconds. What you get: - Pixel-perfect watermark removal. Reverse alpha blending restores original pixels instead of blurring over them. No inpainting artifacts. - Format conversion on download. Save as WebP (~2 MB) or JPEG (~1 MB) instead of the default 8 MB PNG. Pick your format in the popup. - Crop presets for social media (PRO). One click to save in Instagram Square, Feed Portrait, Stories/Reels, YouTube Thumbnail, or Pinterest Pin size. Or set a custom size. - OMNI Video cleanup for supported Gemini MP4 files (PRO). Looks for the visible sparkle mark, cleans it when detected, and keeps the audio. If no mark is found, the file is saved as is. - Auto file renaming. Saved files get clean names like gemini-2026-04-11-001.webp instead of random hashes. - 100% local processing. Images never leave your browser. No uploads, no accounts. - Under 100ms per image.
