Gemini Watermark Remover

No. Everything runs locally in your browser on the HTML canvas — your image is never sent to a server. That makes it instant and completely private.

No. This removes the visible “sparkle” logo in the corner only. Google also embeds SynthID, an invisible watermark across the entire image that survives cropping and compression. No pixel-editing tool can remove it, and AI-detection services that check for SynthID will still identify the image as AI-generated.

No. Only the small region you select is altered — the rest of the image is copied through untouched at full quality. If you crop the logo off, the pixels you keep are pixel-perfect; the dimensions just get a little smaller.

It depends on what's behind the logo. Over a plain sky or a soft background the fill is seamless; over busy detail or text it can look smudged, because a simple fill only borrows from the surrounding pixels. Tightening the box over just the logo usually helps.

Removing watermarks can conflict with Google's terms of service and undercuts the transparency the watermark is meant to provide, so use your own judgment about where a de-watermarked image is appropriate. This tool is offered for legitimate uses like editing your own generations; you are responsible for how you use the result.
