Remove the Gemini or Veo watermark — free.
Drop in an AI-generated video and remove the visible corner watermark. The Gemini diamond is auto-detected and removed exactly — the semi-transparent mark is mathematically reversed, restoring the original pixels with no smudge. The Veo text and other marks use a drag-to-fit paint-over box. Everything runs in your browser, so your video never uploads. It's a cosmetic edit: the invisible SynthID signal stays untouched.
Runs entirely in your browser — your video never leaves your device. This is a cosmetic edit (exact reversal for the Gemini mark, paint-over for others); it does not remove invisible provenance signals such as SynthID, and it doesn't make a video “undetectable” as AI. Only edit videos you have the rights to use. Exact-removal masks from the MIT-licensed GeminiWatermarkTool. Not affiliated with Google, Gemini, or Veo.
How to remove the Gemini or Veo watermark from a video
To remove the Gemini or Veo watermark from a video for free: open this tool, drop in your MP4, drag the box over the mark in the bottom-right corner, and click Remove watermark. It runs in your browser — no upload, no signup, no software to install — and you download a clean MP4. Here are the three steps:
- Add your video. Drop an MP4, MOV, or WebM into the box above. It loads instantly and stays on your device.
- Position the box. A removal box appears over the bottom-right corner — drag it over the Gemini sparkle or the Veo text and resize it to fit snugly.
- Remove and download. Click Remove watermark; the filter paints over the mark frame by frame and hands you a clean MP4 to download.
How the removal works
The visible Gemini watermark is semi-transparent: every watermarked pixel is a known mix of the white diamond and your original frame. For the Gemini diamond, this tool auto-detects the mark and reverses that blend exactly — original = (watermarked − α·logo) / (1 − α) — restoring the true pixels underneath, frame by frame. Nothing is guessed or painted; the result looks like the logo was never there.
For the Veo text mark and any other corner watermark, the fallback is FFmpeg's delogo filter, which reconstructs your chosen box by interpolating from the surrounding pixels. Exact reversal beats interpolation wherever it applies, which is why the tool locks onto the Gemini diamond automatically when it finds one.
Everything happens inside your browser using a WebAssembly build of FFmpeg. When you press Remove watermark, the engine downloads once, your file is read into memory locally, the filter runs, and the result is re-encoded to MP4 — all without a single byte leaving your device. That's why there's no upload progress bar: there is no upload.
Gemini vs Veo watermark: what's the difference?
They're two different marks from the same Google family. The Gemini watermark is a small four-pointed sparkle glyph (from the Gemini app and Nano Banana image/video output). The Veo watermark is a small lowercase “veo” wordmark stamped by Google Flow. Both sit in the bottom-right corner, both are semi-transparent, and both stay put for the whole clip — so the same fixed box removes either one. Use the Gemini/Veo preset to set a sensible starting size, then drag to fit.
On iPhone, Android, and desktop
It works in any modern browser, so there is nothing to install on iPhone, Android, Mac, or Windows. Because the processing happens on your own device, desktops handle longer and higher-resolution clips comfortably, while phones are best for short reels — mobile browsers cap memory far lower, so a 15–30s 1080p clip is the sweet spot on a phone. For a 4K or minutes-long video, use a desktop browser.
Getting the cleanest result
- Keep the box tight. Cover the mark with a little margin, but no more. The smaller the region, the less the interpolation has to invent.
- Busy backgrounds are hardest. Over a flat sky or wall the patch is invisible; over fine detail or fast motion you may see a soft smudge. That's the trade-off of a fast, free, on-device filter.
- Short clips work best. A 15–30s vertical reel at 1080p is the sweet spot. Longer or 4K clips are heavier on browser memory, especially on phones.
What this does not do (SynthID)
This is a cosmetic clean-up, not a provenance eraser. Google embeds an invisible SynthID watermark in every AI-generated image and video; it lives across the whole frame, survives editing, and this tool does not touch it. Removing a corner badge does not make a clip “undetectable” as AI, and you shouldn't treat it that way. Use it to tidy up content you have the rights to — not to misrepresent where something came from.
Frequently asked
How do I remove the Gemini watermark from a video for free?+
Open this page and drop your video in. The tool auto-detects the Gemini diamond and removes it exactly: the semi-transparent mark is mathematically reversed, restoring the original pixels underneath, so there is no blur or smudge. For the Veo text or any other corner mark, drag the box over it and it is painted over instead. Click Remove watermark and download a clean MP4. There is no upload, no signup, and no software to install — it is free.
Do I need to install an app or software?+
No. It runs in any modern web browser — Chrome, Safari, Edge, or Firefox — using an in-browser build of FFmpeg (WebAssembly). Nothing to download or install, and it works the same on Windows, Mac, iPhone, and Android (short clips only on phones).
Do my videos get uploaded anywhere?+
No. The tool runs entirely in your browser using an in-browser build of FFmpeg. Your file is read into local memory, processed on your device, and the result is handed back to you — nothing is uploaded to a server, and nothing is stored. That is also why there is no upload bar: there is no upload.
Is it free?+
Yes — completely free, no signup, no account, no watermark added to the output. It is a standalone utility from Creator Lane, whose main product is Instagram comment-to-DM automation.
Does this remove the invisible SynthID watermark?+
No. Google embeds an invisible SynthID watermark across every AI-generated image and video, and this tool does not touch it. We only remove the visible corner badge — a cosmetic edit. SynthID stays intact, so the clip is not 'undetectable' as AI, and you should not treat it that way.
Which watermarks does it work on?+
The Gemini sparkle glyph gets exact removal — it is auto-detected and mathematically reversed. The small 'veo' text mark from Google Flow and any other static corner watermark are handled with the manual paint-over box, which works whatever tool produced the mark.
What video formats can I use?+
MP4, MOV, and WebM cover almost everything AI video tools export. The output is always an MP4 (H.264 video, AAC audio) so it plays and uploads everywhere — Instagram, TikTok alternatives, YouTube, and any editor.
Why is there still a faint smudge where the watermark was?+
A smudge can only come from the manual paint-over mode, which reconstructs your box by interpolating from the pixels around it — over fine detail or fast motion that can leave a soft patch, so keep the box tight. When the Gemini diamond is auto-detected, the tool uses exact reversal instead: the original pixels are computed back, not guessed, so there is nothing to smudge. If your clip has the Gemini mark but detection missed it, re-add the file and check for the green detection box.
Does it work on my phone?+
Short clips, yes. Because processing happens on your device, long or high-resolution videos can exhaust browser memory on phones (mobile browsers cap memory far lower than desktops). For anything over roughly 30 seconds or 1080p, use a desktop browser.
Can I remove the watermark from images too?+
This tool is built for video. The visible badge on still images is easiest handled with any photo editor's clone or heal tool over the same bottom-right corner. Everything here is tuned for the frame-by-frame video case.
Is it legal to remove the watermark?+
Removing the visible badge for a cosmetic, professional look is generally fine for content you have the rights to use. What is not fine is passing AI-generated content off as something it is not — which is why we leave the invisible SynthID provenance signal untouched. Only edit videos you own or are licensed to use, and follow the terms of whichever tool generated them.
Where is the Gemini or Veo watermark on the video?+
Both sit in the bottom-right corner and stay in the same spot for the whole clip — Gemini stamps a small four-pointed sparkle glyph, and Google Flow stamps a small lowercase 'veo' wordmark. They are semi-transparent, so they can be hard to see over bright or busy scenes. Because they never move, a single fixed box removes them across every frame.
Is this an official Google tool?+
No. This is an independent utility and is not affiliated with, endorsed by, or connected to Google, Gemini, or Veo. Those names are used only to describe which watermark the tool helps you remove.
