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.
How to remove the Gemini watermark from images & video
It takes three quick steps, and everything happens on your own device:
Before and after
The same corner of a Gemini image, straight from the model and after the watermark is removed. The detail underneath the logo comes back — it is not blurred over or patched with invented pixels.
What is the Gemini watermark?
The Gemini watermark is the small four-point sparkle logo that Google stamps into the bottom-right corner of pictures and videos made with its AI tools, including Gemini, the Nano Banana image model, Imagen, Veo and Google Flow. It marks the file as AI-generated, and it sits in the same place at the same size every time, which is exactly why it can be removed cleanly.
There is a second, quieter mark as well. Alongside the visible sparkle, Google embeds SynthID — an invisible watermark spread through the pixels themselves. You cannot see it, resizing or re-saving does not reliably destroy it, and no tool on this page touches it. That means removing the sparkle tidies up how your picture looks; it does not make the file anonymous, and detection services can still flag it as AI-generated.
People usually want the sparkle gone for ordinary reasons: it lands on top of a subject, it clashes with a layout, it breaks a brand template, or it appears in a frame that is about to be cropped and re-used somewhere the corner logo makes no sense. Read the longer guide to the Gemini watermark for how it differs across models.
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.
How this compares with other watermark removers
The differences that actually affect your result:
| Dewatermark | Typical AI inpainting tools | Manual editing | |
|---|---|---|---|
| What happens under the logo | Recovered — the original pixels are restored | Invented by a model, often blurred or smudged | Cloned or painted by hand |
| Your files are uploaded | No — processing stays on your device | Usually yes, to a server | No |
| Cost | Free, no signup, no limits | Often credits, watermarks, or a subscription | Software licence |
| Video support | Yes, every frame | Sometimes, often paid | Frame-by-frame work |
| Effort per file | None — it is automatic | Usually brush or box selection | Minutes of manual work |
| Clean files | Returned untouched | May edit anyway | N/A |
| Removes SynthID | No — and says so | No | No |
No tool anywhere removes SynthID, whatever it claims. Treat that promise as a warning sign.
Who uses it
Supported formats and limits
- Images: PNG, JPEG and WebP. The original PNG from Gemini gives the cleanest result; screenshots and re-saved JPEGs work well too.
- Video: MP4, MOV and WebM, including Veo and Google Flow clips. The cleaned video downloads as WebM.
- File size: there is no upload, so there is no server file-size cap. The practical limit is your own device's memory — very large images and long high-resolution videos take longer and use more of it.
- Resolution: both the standard and the larger Gemini watermark sizes are handled, so small exports and full-resolution renders both work.
- Audio: kept, with the option to drop it.
Getting the best result
- Use the original file. Download straight from Gemini rather than screenshotting or re-saving. Every re-compression loses a little of the information the recovery relies on.
- Do not resize or crop first. The watermark sits at a fixed spot; scaling moves and softens it. Remove the watermark first, then edit.
- Keep PNG for images. Saving as JPEG in between re-compresses the whole picture for no benefit.
- Clean before you edit video. Run the clip through first, then trim, grade and export — otherwise re-encoding has already blurred the logo's edge.
- Check the corner at full zoom. Results are consistent, but a quick look costs nothing before you publish.
- Be straight about AI. The invisible watermark stays, and honesty is usually the better call anyway — disclose AI-generated visuals where it matters.
If something does not work
It said "no watermark found"
The tool checks that the Gemini sparkle really is present before it changes anything, and returns your file untouched when it is not. That usually means one of three things: the file was cropped or resized after it was generated, so the mark is no longer where it should be; it came from a tool that does not use the Gemini mark; or the sparkle really is already gone. Try the original download rather than an edited copy.
A faint outline is left behind
This happens with files that were re-saved as JPEG, screenshotted, or exported from a video editor. Re-compression slightly alters the pixels the recovery depends on, so the logo's soft edge is no longer exact. Starting from the untouched original fixes it.
A video is slow, or the tab stalls
Video is processed frame by frame on your own device, so a long or high-resolution clip takes real time and real memory. Keep the tab in the foreground, close other heavy tabs, and use a desktop rather than a phone for 4K footage.
Frequently asked questions
Is this Gemini watermark remover free?
Yes — completely free, with no signup, no credits and no limits. It runs entirely in your browser.
How do I remove the Gemini watermark from a video?
Drop your Gemini, Veo or Google Flow video onto the page. The watermark is removed from every frame automatically and you can download the clean video when it finishes. There is a dedicated video watermark remover page with more detail.
Are my images or videos uploaded to a server?
No. Everything happens locally in your browser, so your files never leave your device. That is what makes it both private and fast.
Does it make images undetectable as AI?
No. It removes only the visible Gemini sparkle. Gemini files also carry SynthID, an invisible watermark spread through the pixels, which stays in place — so the file can still be identified as AI-generated.
Does it reduce the quality of my image?
No. Only the small corner where the watermark sits is changed, and the pixels there are restored rather than blurred. Everything else in the file is passed through untouched. Saving as PNG keeps it lossless.
Does it work with Nano Banana images?
Yes, if the picture carries the usual corner sparkle — Nano Banana output is watermarked the same way. See the Nano Banana watermark remover page.
Does it work with Google Flow and Veo 3 videos?
Yes. Flow clips are Veo output and carry the same corner mark, so the video path handles them like any other Gemini video. There is a Google Flow watermark remover page for that workflow.
What about Imagen or images from Google AI Studio?
Anything carrying the standard Gemini corner sparkle is handled, which covers Imagen renders and images pulled out of AI Studio. The tool checks each file first, so if the mark is not the one it knows, your file comes back untouched instead of damaged.
Which files give the best result?
The original file straight from Gemini. Screenshots and re-saved JPEGs still work well, they just need a light extra pass along the logo's edge.
Why did it say "no watermark found"?
It only edits files that actually have the Gemini sparkle, so a clean image is returned exactly as it was. If you expected a watermark, check that it is in the bottom-right corner and that the file has not been resized or cropped since it was generated.
Is it legal to remove the Gemini watermark?
That depends on your file, your jurisdiction and the terms you agreed to when you generated it, so treat this as information rather than legal advice. Removing a mark from your own generated work for layout reasons is very different from stripping attribution to pass AI content off as something else, or from editing a file you have no rights to. Google's terms for its AI tools are the place to start, and the invisible watermark remains regardless.
Has the Gemini watermark changed?
Google does adjust its models and marks over time, and different tools use different watermark sizes. The removal is measured from real Gemini output and re-checked against new files, so when a new variant appears the measurements are refreshed. If a file of yours is not recognised, that is worth telling us about via the contact page.
Do I need to install anything?
No. There is no app, extension or download — the page itself does the work. It runs on a phone as well as a desktop, though large videos are much quicker on a computer.
Can I remove other companies' watermarks with it?
No. It is built specifically around the Gemini sparkle and deliberately does nothing to files that do not carry it.
