Gemini Watermark Remover
Take off Google Gemini's corner sparkle, its hidden SynthID mark, and its AI metadata.
Every image from Google Gemini (and Imagen) comes stamped: a small ✦ sparkle in the corner, an invisible SynthID pattern in the pixels, and C2PA metadata that says “Made with Google AI.”
Unmarkr removes all three. Check any Gemini image free to see exactly what it carries, then clean it at full resolution.

Frequently asked
- Where is the Gemini watermark?
- There are up to three: a visible ✦ usually in a corner, an invisible SynthID pattern across all the pixels, and C2PA metadata inside the file.
- Can you remove the invisible one?
- Advanced removal rebuilds the image so the hidden SynthID signal is replaced. It's effective but, like any SynthID tool, not guaranteed on every image.
- Does the sparkle removal look clean?
- Yes — the corner region is reconstructed to match the surrounding image, not blurred over.
- Is my image uploaded to check it?
- We don’t keep your images — files aren’t stored after you download.
- Is it free?
- Removing AI metadata is free. Deep removal — the hidden SynthID watermark and the visible logo — uses credits (new accounts start with 7 free).
