Gemini Watermark Remover.

The Gemini Watermark Remover above removes the Gemini sparkle logo and Google C2PA labels from Gemini and Nano Banana images. Signed-in visitors can also break the invisible SynthID pixel mark.

Remove The Gemini Sparkle Logo

The sparkle sits in the bottom-right corner. The tool clears it by working out the pixels under the logo, using an open-source engine built for Gemini images. It worked on all 25 Gemini samples we tested, from 1:1 to 21:9 and 2816×1536. The result screen shows a before and after zoom of the corner.

Logo removal re-saves the file. A PNG stays a PNG. JPG and WebP are saved at 95% quality.

Remove Google C2PA And Break SynthID

The tool strips the Google C2PA Content Credentials in your browser, naming Google as the maker in the checklist. SynthID lives in the pixels and is invisible to users. Log in and tick the Invisible pixel watermark row to regenerate the image and break it. It is best-effort, so a detector could still flag it. Pick Gentle to keep the picture close, or Strong to push harder.

Gemini’s Media Watermark Setting

Since 14 August 2026 Gemini has a Media watermark setting. Turned off, it hides the sparkle on new images. On is the default, and some countries do not get the switch. SynthID and C2PA stay either way, so the tool still has work to do on older and new images.

How To Use It
