Remove Gemini Watermarks Online

This is the browser version of the Erasio engine. Drop in an image or MP4 that Google Gemini, Google AI Studio or Google Flow generated, and the visible sparkle watermark is removed on your own device — nothing is uploaded, and the cleaned file is handed straight back to you.

It covers every Gemini image variant, including the standard sparkle, the compact Nano Banana mark from lightweight tiers, and AI Studio output. For video it handles Gemini Omni and Google Flow exports, rebuilding each frame and re-muxing with your original audio untouched.

Detection and removal both run in your browser against calibration data bundled with the page. Images go through the Canvas API; video is demuxed, patched frame by frame and re-muxed through WebCodecs. No file, no frame and no filename ever reaches a server.

The practical consequences are worth knowing. Processing speed depends on your machine rather than our capacity, so a long clip takes longer on a laptop than a workstation. The tool keeps working if you lose connectivity after the page has loaded. And because we never receive your media, we cannot see, store or recover it — which is the point.

A composited watermark is a weighted blend of the original pixel and the logo at a known opacity, and that blend is invertible. Erasio solves for the original pixel arithmetically instead of masking the region and asking a generative model to invent a replacement.

That is why output has no halo at the watermark boundary and no smeared texture where detail ran beneath the logo — nothing was replaced, so there is no seam. Images export as lossless PNG so the recovered values survive intact. Video must be re-encoded, since every frame genuinely changes, but the target bitrate is derived from your source clip rather than a fixed default, and resolution and frame rate pass through unchanged.

The trade-off is that inversion needs the original file. A screenshot or a re-compressed copy no longer carries the exact blended values, so removal will not resolve cleanly. Always start from the file Gemini or Flow gave you.

Erasio removes the visible logo and nothing else. SynthID — Google's invisible provenance signal, distributed across the whole pixel grid — survives re-encoding and is untouched, so a cleaned file still identifies as AI-generated to anything reading for it.

The engine is calibrated to Google's specific patterns, so it does nothing at all with watermarks belonging to stock libraries, photographers or other creators. It is for media you generated and have the right to use.
