Gemini Watermark Remover

Remove Gemini Watermarks Instantly — Right From Your Browser Toolbar
Tired of opening a new tab every time you want to clean a Gemini-generated image? The Gemini Watermark Remover extension puts the same pixel-perfect watermark removal tool from QuickImageFix.pro directly into your Chrome toolbar — one click, no website visits required.
Upload your image, remove the Nano Banana star logo, and download the clean result — all without ever leaving the page you're on.

🔧 HOW IT WORKS
Most watermark removers use AI inpainting — they look at surrounding pixels and guess what was underneath. That approach fails on textured backgrounds and leaves soft smears that can look worse than the watermark itself.
This extension uses a completely different method: reverse alpha compositing.
Google applies the Gemini watermark using a fixed mathematical formula:
final pixel = (alpha × 255) + (1 − alpha) × original pixel
Because the watermark shape, position, and opacity map are identical across every Gemini image, the formula can be reversed exactly to recover the original pixels — with an error margin of just ±1 per channel. That's completely invisible to the human eye, even at 100% zoom.
No guessing. No AI fill. Just math.

✨ KEY FEATURES
✅ One-Click Access — Available right from your Chrome toolbar. No need to visit the website every time.
✅ Pixel-Perfect Removal — Uses reverse alpha compositing, not AI inpainting. Recovers original pixel values mathematically with ±1 error margin per channel.
✅ Auto-Detects Watermark Size — Gemini uses two watermark sizes: 48×48px for smaller images and 96×96px for larger ones. The tool auto-detects which variant your image uses and applies the correct alpha map automatically.
✅ Batch Processing — Upload and process up to 10 images at once. Download them all as a single ZIP file.
✅ Multiple Output Formats — Export your cleaned image as PNG, JPEG, or WebP. Adjust output quality (original, medium, or compressed) depending on your needs.
✅ Works on Gemini & Google AI Studio — Both gemini.google.com and aistudio.google.com use the identical Nano Banana star watermark. This extension handles both sources without any extra configuration.
✅ 100% Local Processing — All computation runs directly in your browser. Your images are never uploaded to any server — not during processing, not for logging, not for any reason. You can even disconnect your internet after the extension loads and it will continue working perfectly.
✅ No Account, No Signup, No Limits — Open the extension, upload your image, download the result. Nothing locked behind a login.
✅ Works on All Devices — Chrome on Windows, macOS, and Linux. No additional setup needed.

📂 SUPPORTED FORMATS

Input: PNG, JPG / JPEG, WebP
Output: PNG, JPEG, WebP (your choice)

Google Gemini typically generates images as PNG — this extension is optimized for that workflow.

💡 FOR BEST RESULTS
Always use Save Image directly from within Gemini — right-click the image and select "Save Image As." Do not screenshot it. Screenshots introduce compression and pixel scaling that permanently alter pixel values and reduce restoration quality, because the reverse formula depends on the original unaltered pixel data.

⚠️ WHAT THIS EXTENSION DOES AND DOESN'T REMOVE
✅ Removed: The visible Gemini / Nano Banana star watermark in the bottom-right corner of AI-generated images.
⚠️ Separate tool needed: The invisible C2PA AI content credential that triggers "Made with AI" on Instagram, LinkedIn, and Pinterest. Use the AI Metadata & Prompt Scrubber on QuickImageFix.pro for this.
❌ Cannot be removed: SynthID (frequency-domain signal — no pixel or metadata tool can affect it).
❌ Not applicable: Watermarks from Midjourney, DALL-E, Stable Diffusion, or other AI platforms. Manually added text or logo watermarks. Images that were screenshotted or recompressed before uploading.

🔒 PRIVACY FIRST
This extension does not collect any data. It does not track usage. It does not send your images anywhere. Everything happens locally inside your browser the moment you upload a file. There are no analytics, no telemetry, and no third-party services involved in image processing.

Built by the team at QuickImageFix.pro — free image tools that respect your privacy and work without making you sign up for anything.
