Ready. Your image will be processed on this device.
Phones can take longer. Large images may fail if your browser runs out of memory. Your original file is never overwritten.
What this tool changes
Reverse alpha blending subtracts a matched white watermark overlay and reconstructs the pixels beneath it. It does not paint or generate replacement content.
For Nano Banana exports, check the corner preview first: the same visible corner overlay is handled here; marks in other positions go to the manual brush workflow.
This version checks supported corner layouts. Cropped, resized, heavily compressed images or unfamiliar watermark versions may not match. Check the Gemini image watermark in the preview: exact recovery is not guaranteed. Invisible provenance marks are outside this tool’s scope.
If this browser tool cannot match the watermark version, try Wondershare UniConverter AI Watermark Remover for an AI-assisted alternative.
Formats and limits
Input: PNG, JPG/JPEG or WebP. Output: choose PNG or JPG. PNG avoids additional lossy compression; JPG uses lossy compression and a white background for transparency.

How to remove a Gemini watermark from a downloaded image
For a supported Gemini corner layout, choose the downloaded image, check the processed preview, and download it as PNG or JPG.
Choose a PNG, JPG/JPEG or WebP file, then inspect the corner before downloading; cropped, resized, heavily compressed images or unfamiliar watermark versions may not match.
This tool addresses the visible mark, not invisible provenance marks. Google explains the distinction in its official Gemini watermark guidance.
What the Gemini watermark on an image is and where it sits
The Gemini watermark this tool targets is a visible white overlay in a supported corner layout.
Inspect the corner preview rather than assuming every watermark version will match; exact recovery is not guaranteed.
Visible watermarks and invisible provenance marks are separate layers, as described in Google's official Gemini watermark guidance; invisible provenance marks are outside this tool's scope.
