How to Get Best Results

Use the Original Downloaded File

This tool only works with the original image file downloaded directly from Gemini. The algorithm depends on exact pixel values preserved only in the original file.

Do Not Crop or Resize the Image

The watermark position is calculated from image dimensions. Cropping, resizing, or any transformation shifts the watermark coordinates and breaks detection.

No Screenshots or Re-saves

Screenshots and re-saved images introduce compression artifacts or alter pixel data. Always use the original file as downloaded from Gemini.

Supported Formats

Upload JPG, PNG, or WebP files. The processed result is always exported as a lossless PNG to preserve quality.
