Google Flow Watermark Remover
Remove the watermark from any video exported from Google Flow (labs.google/fx/tools/flow). Erasio detects the watermark variant automatically — Omni Flash, Veo 3, or whichever model Flow used — and rebuilds every frame in your browser. Original audio preserved, no upload, no quality loss.
What Google Flow is — and why every export carries a watermark
Google Flow is Google's filmmaker-facing AI video studio at labs.google/fx/tools/flow. It's a single workspace that wraps multiple underlying video models — Omni Flash for fast generations, Veo 3 for higher-fidelity clips — and stamps a Gemini-family sparkle logo on every export. The exact pattern depends on which model rendered the clip, and the alpha map differs slightly between them. Erasio identifies the variant on upload and applies the matching reverse alpha blend, frame by frame, with the original audio track copied across byte-for-byte. One Flow export, one drop, one clean MP4.

Clean a Google Flow export in three steps
Drop, process, download. Nothing leaves your browser.
Generate or export a clip in Google Flow
Standard Flow workflow at labs.google/fx/tools/flow — generate the clip, export the MP4.
Drop the export into Erasio
Drag in the watermarked MP4. Erasio identifies which Flow model rendered the clip and selects the right alpha map automatically.
Download the clean MP4
Same resolution, same framerate, same audio. The visible sparkle is gone — ready for client delivery, social upload, or paid distribution.
Built for the Google Flow workspace — every model Flow ships, one engine
Private by design
Files never leave your browser. The math runs locally on the Canvas / WebCodecs APIs — there is no upload step to leak from.
Lossless reverse-blend
Other tools paint over the sparkle with AI guesses. Erasio reverses the exact alpha blend Google used, recovering the original pixels.
Every Gemini variant
Gemini, Gemini Omni, Omni Flash, Nano Banana, Sparkle v1 and v2 — one engine, all patterns, kept current.

Google Flow Watermark Remover — common questions
Is the Gemini Omni Watermark Remover really free?
Yes. The Erasio online tool is free for guests with no signup and lets you process a Gemini Omni image or short video right in the browser. Sign in (also free) to remove watermarks in bulk, queue multiple files at once, and download them as a single ZIP.
Do my files get uploaded to a server?
No. Erasio runs entirely in your browser using WebCodecs and the Canvas API. Your Gemini Omni image or video is read into memory, the watermarked region is patched locally, and the clean file is handed back to you — nothing is transmitted, logged, or stored on our servers.
Does removing the watermark hurt the image or video quality?
No. Erasio uses reverse alpha blending — a deterministic mathematical inverse of the blend Google used to stamp the watermark on. The patched pixels are the original pixels, not an AI guess. Images are exported as lossless PNG; video is re-encoded at a high bitrate so the output is visually indistinguishable from the source.
Will the audio in my Gemini Omni video survive?
Yes. The video pipeline demuxes the original audio track, processes only the video stream, and re-muxes the original audio back in unchanged. You get the same audio in the clean MP4 as the watermarked one.
What about SynthID — the invisible watermark Google embeds?
Erasio only removes the visible Gemini Omni sparkle logo. SynthID is an invisible provenance signal embedded directly into pixel values and is not removed by reverse alpha blending. If you need a tool that strips SynthID, you should know that doing so may violate Google's terms and most platforms' AI-content policies — Erasio deliberately stops at the visible mark.
Does it work for videos from Google Flow (Omni Flash)?
Yes. The Omni Flash watermark pattern that Google Flow stamps on labs.google/fx/tools/flow exports is detected automatically. Both the online tool and the Chrome extension support it, and the Chrome extension cleans Flow exports the moment you download them — zero extra clicks.
Chrome extension or online tool — which should I use?
Use the Chrome extension if you generate Gemini Omni content regularly: it cleans every download automatically and you never see a watermark in your saved files. Use the online tool for one-off cleans, files saved to other devices, or files generated before you installed the extension.
Does the Gemini Omni Watermark Remover work on mobile?
The online tool works on any modern mobile browser. The Chrome extension is desktop-only. Video processing is fastest on desktop where the WebCodecs APIs are most performant; mobile works but takes longer per clip.
Is this legal?
Erasio is a local media-processing tool — it operates on files you've already downloaded, with no unauthorized interaction with Google's servers. You are responsible for ensuring that your use of any AI-generated content complies with Google's terms, copyright law, and the upload policy of whatever platform you share it on. Don't remove watermarks from content you don't have the right to use.
Will Erasio still work when Google updates the Gemini Omni watermark?
Yes — we actively track every Gemini, Omni, Omni Flash, and Nano Banana watermark variant Google ships and update Erasio whenever the pattern changes. All updates are free; the Chrome extension auto-updates and the online tool gets new patterns server-side.
