Only clean images you made or have the right to edit. This removes the visible sparkle only: Google’s invisible SynthID watermark stays in the image.

How to remove the Gemini watermark from an image

1
Download the original image
In the Gemini app, gemini.google.com or Google Flow, open the image and download the full-size file. A screenshot or a copy pasted from a chat is smaller and blurs the sparkle, which makes a clean removal harder.
2
Drop it on the box above
One image or fifty, dragged in or picked from a folder. Each is cleaned the moment it arrives, on your own device, usually in well under a second.
3
Compare and download
Check the zoomed corner before and after, then download each image, or all of them as one ZIP. PNGs stay lossless PNG; JPG and WebP are saved in their own format at high quality.

Google Flow images and the visible watermark

Flow is where many people make Nano Banana images alongside their Veo videos. Google’s Flow help page says a visible watermark can be added to images as well as videos, controlled by the Visible watermarking switch in the menu under your profile picture.

In India, South Korea and Vietnam that switch is not yours to turn off: the visible watermark is added unless you are on Google’s top AI Ultra plan. Images you made before switching it off keep their mark too. When a Flow image comes out with the Gemini sparkle in the corner, drop it here like any other.

Flow videos carry the word "Veo" instead, and need a video tool: the Flow AI Watermark Remover takes it out, also free and in your browser.

What the Gemini watermark looks like

Images from the Gemini app, including those made with its Nano Banana models, carry a small four-point sparkle near the bottom-right corner: Gemini’s logo, laid over the picture in semi-transparent white. It is a label that says the image came from Google AI, separate from SynthID, the invisible watermark Google also puts in the pixels.

Gemini has changed the sparkle’s size, its distance from the edges and how strongly it is drawn more than once, so a remover that expects it in one fixed spot misses or smudges many images. These are the layouts this tool was tested on:

Where Gemini puts the sparkle
Images	Sparkle	From the right and bottom edges
1K images, up to 1024px on a side	48 × 48px	32px
Larger images, both sides over 1024px	96 × 96px	64px
Many 1K images since mid-2026	48 × 48px, fainter	96px
2K images since May 2026	96 × 96px, fainter with a brighter rim	192px
Resized or re-saved copies	Any size in between	In proportion

Instead of guessing from the image size, the tool searches the corner for the sparkle’s outline at every size and distance, pins it down to a fraction of a pixel and measures how strongly it was drawn. That way the next layout Gemini switches to is likely covered as well.

How it removes the sparkle without blurring

Gemini blends the sparkle in with a fixed formula: every pixel under it becomes a mix of white and its original colour, weighted by how opaque the sparkle is at that spot. The sparkle’s opacity is known exactly, measured by drawing it over pure black, so the formula can be run backwards to get each original colour back. This is called reverse alpha blending.

Nothing is painted over or made up by AI. Pixels outside the sparkle are left exactly as they are, and under it the colours come back from the image itself, so grass, skin, fabric or text keep their real detail. That is the difference from Photoshop’s healing brush, Canva or Magic Eraser, which guess what was there and often leave a soft patch.

Pixels that were already pure white under the sparkle stay white: there is nothing to recover there, and nothing is needed.
JPG files and resized copies have lost a little detail, so a faint outline can very occasionally remain. The original PNG always comes out cleanest.
Only the Gemini sparkle is removed. Text, logos or other marks added by you or another app stay.

Gemini has a watermark switch now. Do you still need this?

Often, yes. Since August 2026 the Gemini web app has a Media Watermark setting that stops the sparkle on new images. It only covers what you make after switching it off, it has not reached every phone app, and in India, South Korea and Vietnam only Google AI Ultra subscribers get it. SynthID stays either way.

Some users also report that with the watermark off, Gemini hands back a JPG instead of the full-quality PNG. Keeping the watermark on, downloading the PNG and removing the sparkle here keeps the best file.

Nano Banana watermark remover

Nano Banana is Gemini’s image generation and editing model, and its newer versions are called Nano Banana Pro and Nano Banana 2. Images made with any of them in the Gemini app carry the same sparkle, so this page is a Nano Banana watermark remover too. Images made through the Gemini API or Google AI Studio usually have no visible sparkle at all, only SynthID.

The visible sparkle, not SynthID

Gemini images carry two watermarks. The sparkle is the one you can see. SynthID is an invisible pattern spread through the whole image that Google’s tools can still read after the image is cropped, resized or compressed.

This tool removes the sparkle only. It does not remove, weaken or test for SynthID: Google’s SynthID Detector and the Gemini app can still tell that a cleaned image came from Google AI. Removing the sparkle does not turn an AI image into a photo, so label it as AI-generated wherever that is expected.

Use it responsibly

Clean only images you made yourself or have permission to edit.
Gemini and Flow are covered by Google’s terms. Check them before you publish edited images.
Label AI images as AI where the law asks for it, as the EU AI Act does, and where Instagram, TikTok or YouTube ask you to.
Do not use clean images to pass AI pictures off as real photos of real people or events.

Gemini watermark remover FAQ

Is it possible to remove the Gemini watermark?

Yes. Gemini draws its sparkle over the picture with a fixed, known formula, so it can be run backwards to get the pixels underneath back. This page does that in your browser, free, for images from Gemini, Nano Banana and Google Flow.

Is the Gemini watermark remover free?

Yes, with no sign-up, no daily limit and no watermark of our own. It costs nothing to run because the work happens on your device.

Can Google AI remove watermarks?

Gemini can paint out marks in a photo you give it, but it will not reliably remove its own sparkle, and every image it returns gets a sparkle of its own. This tool removes the sparkle exactly, without generating anything new.

Do Google Flow images have a watermark?

They can. Flow adds a visible watermark to images when Visible watermarking is on, and always in India, South Korea and Vietnam unless you are on the top AI Ultra plan. Every Flow image also carries SynthID. If yours shows the Gemini sparkle, drop it here.

Do Gemini Pro and Ultra images have a watermark?

On Google AI Pro, images get the sparkle unless you can switch Media Watermark off. Ultra subscribers can switch it off everywhere, including India, South Korea and Vietnam. SynthID is added on every plan.

Are my images uploaded anywhere?

No. Your browser opens, cleans and saves them. They are never sent to our servers or anyone else’s, and closing the tab clears them.

Can I remove the watermark from many images at once?

Yes. Drop up to 50 images at a time. Each is cleaned as it arrives, and Download all packs the results into one ZIP file.

Will the image lose quality?

No. Only the pixels under the sparkle change, and they are recovered from the image rather than painted over. Size, sharpness and colours stay as they were, and PNGs are saved losslessly.

Does it remove SynthID?

No. It removes only the visible sparkle. SynthID, Google’s invisible watermark, stays in the image.

Why was no watermark found in my image?

Either the image has no visible sparkle, as with the Gemini API, Google AI Studio or the watermark switched off, or the sparkle was cropped, covered or blurred in a screenshot or compressed copy. Try the original download.

Does it work on Veo or Gemini videos?

No, this page is for images. For Flow and Gemini videos, use the Flow AI Watermark Remover, which takes out the "Veo" text and the sparkle from MP4s, also free in your browser.

Is Flow AI Studio part of Google?

No. Flow AI Studio is an independent tool and is not affiliated with, endorsed by or connected to Google.
