Watermark Remover for Gemini & Nano Banana

Most watermark removal tools focus on images. This extension also supports video.

* Process videos frame by frame * Preserve the original video resolution * Keep the original audio track * Avoid unnecessary downscaling * Process videos locally without uploading them

## ⚡ Automatic Image Cleaning

Remove the visible watermark automatically when downloading images from Gemini.

1. Install the extension. 2. Open the extension and enable Auto-Clean. 3. Generate an image in Gemini or Nano Banana. 4. Download the image normally. 5. The cleaned version is automatically saved to your downloads folder.

No manual editing or separate application is required.

## 🛠️ Manual Image & Video Cleaner

You can also clean files manually using the built-in cleaner.

1. Open the extension from your Chrome toolbar. 2. Select the built-in cleaner. 3. Drop in your Gemini or Nano Banana image or video. 4. Process and download the cleaned file.

## 🔬 Reverse Alpha Blending

Traditional watermark removal tools often use blur or AI inpainting. These methods attempt to reconstruct the area underneath the watermark and can affect details such as faces, text, and fine textures.

This extension uses reverse alpha blending to calculate and restore the underlying pixels from the supported watermark overlay.

For the best results, use the original file downloaded directly from Gemini. Screenshots, crops, and recompressed files can change the watermark pattern and may prevent accurate restoration.
