Gemini Watermark Remover

One-click Gemini watermark remover for images and OMNI videos. 15 free cleans, 100% local, no uploads. 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.
• Manual image cleanup fallback. If automatic cleanup leaves a visible trace on a hard image, open Manual Clean, paint that area yourself, and download the locally cleaned PNG.
• 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. You won't notice it running.

Works with the built-in download button on gemini.google.com and Google AI Studio. Compatible with any Chromium-based browser.

15 free cleanups included. PRO: $2.99/month or $24.99/year (save 30%). Pay with credit card, Apple Pay, Google Pay, or Telegram Stars. Cancel anytime.
