The Gemini watermark is a four-pointed star icon that Google automatically adds to the bottom-right corner of all AI-generated images created with Google Gemini. This visible watermark identifies images as AI-generated content.

Many users want to remove this watermark for cleaner presentations, social media posts, or professional use. Our free Gemini watermark remover tool processes images directly in your browser without uploading to any server.

How Does Our Watermark Remover Work?

Our tool uses two advanced technologies working together:

Smart Brush Selection

The Smart Brush is an intelligent selection tool that detects watermark edges automatically. When you paint near a watermark, it expands to select the entire watermark area precisely - no need to trace exact boundaries.

Biharmonic Inpainting

Once you select the watermark with Smart Brush, our Biharmonic Inpainting algorithm fills the area seamlessly. This is the same mathematical technique used in professional photo editing software.
