Erasio removes Gemini watermarks by reverse-calculating the alpha-compositing math that Google used to embed them, recovering the original pixels exactly. For images it patches the watermarked region directly; for video it rebuilds every frame and re-wraps the clip with the original audio. All processing happens locally in your browser — your files never leave your device.

Yes — Erasio removes the watermark from Gemini videos, including Google Omni clips and Omni Flash videos exported from Google Flow. Drop an MP4 into the online tool, or download directly with the Chrome extension, and Erasio strips the sparkle watermark from every frame. The result is a clean MP4 with the original audio preserved — no re-shooting and no editing suite required.

Yes — Erasio supports Google Flow videos and removes the Omni Flash watermark from clips generated at labs.google/fx/tools/flow. The Chrome extension activates on Google Flow in addition to Gemini and AI Studio, and removes the watermark from videos generated with Google's Omni Flash model as you download them. You can also drop an exported Flow MP4 into the online tool to clean it after the fact — Erasio detects the Omni Flash watermark pattern automatically and rebuilds every frame with the original audio kept intact.

No — Erasio keeps the original audio track and re-encodes at a high bitrate, so visual quality and audio are effectively unchanged. The processor re-renders the video frames to remove the watermark while copying the audio stream across verbatim. The only thing that changes is that the visible watermark is gone.

Yes — Erasio is fully client-side and never sends your images or videos to any server. The Chrome extension only requires permissions to operate on gemini.google.com, aistudio.google.com, and labs.google/fx/tools/flow. It does not access other websites, read your browsing data, or transmit any information.

Yes — Erasio supports every Gemini, Google AI Studio, and Google Flow image or video that carries the standard sparkle, Nano Banana, or Omni Flash watermark pattern. v1, v2, and every variant in between are all covered. Files without a watermark are passed through unchanged.

The Nano Banana watermark is the compact, lower-alpha variant of the Gemini sparkle mark, embedded in outputs from lightweight Gemini model tiers. It is typically a smaller, lower-alpha overlay compared to the standard mark. Erasio detects and removes it with the same precision as every other supported variant.

The Chrome Extension cleans Gemini downloads automatically at the browser level, while the Online Tool is a standalone page for uploading images or MP4s by hand. Both share the same in-browser reverse alpha-blending engine, so output quality is identical — the only difference is whether removal happens at download time or after the fact.

Erasio's Online Tool works on any modern mobile browser, but the Chrome Extension is desktop-only. You can clean images and videos from your phone or tablet through the web tool (video processing is fastest on desktop where WebCodecs APIs are most performant).

Yes — Erasio ships a matching update whenever Google changes a Gemini, Nano Banana, or Omni Flash watermark pattern. We actively monitor changes to Gemini's watermark patterns across every variant. All updates are included at no extra cost.

No — Erasio is a local media processing tool that operates on files after they are downloaded, with no unauthorized interaction with Google's servers. It processes images and videos after download. Users are responsible for ensuring their use of generated content complies with applicable terms.
