Google Flow & Veo watermark remover

Removing a different watermark

The tool above knows the Gemini watermark by heart. It can also learn a watermark it has never seen — any see-through logo that sits in the same spot on every picture, from any tool.

Add 3 or more pictures that share the same watermark (more is better — around 20 gives the sharpest result). Because the logo stays put while the pictures underneath differ, it can be told apart from your content and then removed the same exact way, restoring what was underneath rather than blurring it. As always, nothing is uploaded.

Flow, Veo and the same corner mark

Google Flow is Google's AI filmmaking tool, and the shots it produces come from Veo. Both mark their video the way Gemini marks images: a four-point sparkle in the bottom-right corner, in the same place in every frame. So a Flow download, a Veo 3 clip and a Gemini video all take the same path through this tool.

That corner logo is a particular nuisance in filmmaking work, because footage gets re-framed. A badge that sat politely in the corner of the original ends up in the middle of a vertical crop, or over a lower third, or fighting a title card. Clearing it first leaves you free to cut the shot however the edit needs.

Working it into an edit

• Clean the raw download first, before trimming, grading or exporting — each pass adds compression that blurs the logo's edge.
• Audio is preserved, so dialogue and sound design survive the round-trip; there is a checkbox if you want it dropped.
• The corner will not flicker. The correction is smoothed across frames, so it holds steady through motion.
• Allow roughly the clip's length, and use a desktop for long or high-resolution sequences.

Multi-shot sequences

Flow projects are usually built from several generated shots cut together, and every one of them arrives with its own corner sparkle. It is worth cleaning each clip as you bring it in, before it goes on the timeline — once shots are joined, colour-graded and exported as a single file, you are working from footage that has been compressed again, and the logo edges in it are softer than they were in the originals.

The same applies to still frames pulled out of Flow for thumbnails or storyboards: grab them from the cleaned clip rather than the original download, or run the exported frame through the image watermark remover.

Whichever route you take, the invisible SynthID mark stays in the file, so the footage remains identifiable as AI-generated — see the watermark guide for what that means.

How the removal works

Most watermark removers guess. They erase the area and ask an AI model to paint something plausible into the hole, which is why results so often look smeared, or invent detail that was never there. This tool does something different: it undoes the watermark instead of covering it up.

The sparkle is a semi-transparent layer blended over your picture, so every watermarked pixel is a fixed mix of two things — the logo, and whatever was underneath. Because the logo is identical in every Gemini file, that mix can be measured once and then reversed, pixel by pixel, to recover the original colour. The result is the detail that was actually behind the logo, not a plausible imitation of it.

Why that matters for quality

• Nothing outside the corner is touched. The rest of your image is passed through unchanged, so there is no global quality loss.
• No blur, no smearing. Textures, edges and text under the logo come back as they were.
• It refuses to guess. If the Gemini sparkle is not actually present, the file is returned exactly as you gave it, rather than having an odd bright patch stamped into the corner.

Files that were re-saved or re-compressed after watermarking — a JPEG export, a screenshot, or any video frame — no longer hold the exact original values, so a light extra pass tidies the logo's soft edge in those cases.
