About GeminiLogo

GeminiLogo is built and maintained by edmond, an independent developer. It is a single-page tool with one narrow job: reviewing and reconstructing the visible Gemini sparkle region on AI-generated images, entirely in your browser.

Why this exists

Most watermark tools ask you to upload your image to a server and promise results they cannot show you in advance. This site takes the opposite approach: pixels never leave your device, the math is deterministic rather than generative, and you see the exact output before anything downloads. The scope is deliberately small — one validated watermark profile, honest failure modes, and a crop fallback when reconstruction is not the right call.

What this site is not

GeminiLogo.com is an independent tool and is not affiliated with, endorsed by, or sponsored by Google LLC. Gemini™ and the Gemini logo are trademarks of Google LLC. The tool addresses the visible corner sparkle only — it does not detect, remove, or alter SynthID, and our terms ask you to edit only images you are authorized to edit and to follow the disclosure rules that apply where you publish.
