It announces 'AI-made'
The corner sparkle logo tells every viewer the image came from Gemini before you have said a word about the work.
A free Gemini watermark remover that erases the sparkle logo from the bottom-right corner of your AI images — no upload, no sign-up, and no generative repainting. Everything runs in your browser.
What changes
It rebuilds one thing: the confirmed 48×48 region, typically the sparkle logo in the bottom-right corner, using reverse alpha math — no generative repainting, no edits anywhere else. Every other pixel stays exactly as decoded, and the file you download matches the preview you approve, byte for byte.
Know the mark
The Gemini watermark is the small sparkle icon — often called the Gemini logo or badge — stamped on images generated on the Free and Pro tiers, including Nano Banana generations. On current exports it is 48×48 pixels, set 96 pixels in from the bottom-right corner; we last re-verified that spec against a fresh iPhone export on Aug 9, 2026.
It is separate from SynthID, Google's invisible watermark: removing the visible sparkle changes nothing about SynthID. The full guide covers versions, positions, and what each mark means.
The sparkle problem
Visibility
The corner sparkle logo tells every viewer the image came from Gemini before you have said a word about the work.
Polish
A vendor logo on client mockups, thumbnails, or slides undercuts the finish of an otherwise final asset.
Default-on
Free and Pro Gemini exports carry the logo by default, and those tiers have no toggle to turn it off. For an existing export, cropping or local reconstruction are the routes to a clean visible canvas.
The file is decoded locally and the exact before/after preview is generated in your browser. Nothing is uploaded.
Compare the reconstructed corner against the original at 4×. If the sparkle sits elsewhere, adjust the fixed box and the preview regenerates.
The file you save is byte-identical to the preview you see, and nothing downloads automatically. Artifact warnings stay visible right next to the download button.
Private by architecture
Your image stays in this tab: the browser decodes the source, applies the selected operation, and builds the final PNG locally. There is no image-processing API, account, or server-side upload path. It works online in any modern browser — desktop or phone — with no extension or app to install.
Pixels and filenames are not sent to GeminiLogo.com.
The validated box uses reverse alpha math, not a generative fill.
The download reuses the exact in-memory PNG Blob you reviewed.
Approaches compared
The difference is what each method does to your pixels: cropping cuts them away, AI inpainting reinvents them, and reverse reconstruction restores the documented overlay.
| Capability | Crop the corner | AI inpainting | Reverse reconstruction |
|---|---|---|---|
| Keeps full image dimensions | No | Yes | Yes |
| No AI-invented pixels | Yes | No | Yes |
| Pixels outside the corner untouched | Yes | Depends on the tool | Yes |
| Runs locally with no upload | Depends on the tool | Depends on the tool | Yes |
| Exact before/after preview of the download | Depends on the tool | Depends on the tool | Yes |
AI inpainting redraws the corner and often more than the corner: users of generative removers report whole-image drift and softer output, because a model reinvents pixels it never saw. Reverse reconstruction has nothing to reinvent — it reverses a documented overlay and leaves every other pixel alone.
Crop is not a rival — it ships inside this tool as the fallback for unsupported sizes, and reverse reconstruction applies only to validated sizes and original-quality inputs; see the scope below.
Kept current
This Gemini watermark remover currently supports four export sizes: 1024×1024, 1376×768, 768×1376, and 1408×768. A size joins the list only after its reverse-alpha reconstruction passes a three-for-three clean-output gate on original-quality exports.
If your size is not listed, the tool says so and offers a plain edge crop instead.
Scope and limits
Reconstruct a user-confirmed 48×48 visible sparkle region on one validated profile. Clean results are promised only for original-quality inputs, typically original Gemini PNG exports. Crop is always available as an alternative. Compression warnings are best-effort, so always review the exact before/after. The tool never switches modes or downloads automatically.
It does not remove SynthID, make AI content undetectable, restore unknowable original pixels, or guarantee artifact-free reconstruction after resizing or recompression.
Learn how the visible watermark differs from SynthID before editing, and if you would rather start from a clean export, compare the official routes to a Gemini image without the watermark.
Before you process an image
Only the selected 48×48 sparkle-logo region, on a validated image size. The reverse math rebuilds that corner and repaints nothing else. To get rid of the icon, confirm the region in the preview and download the rebuilt file.
No. Decoding, region selection, reconstruction, preview, and PNG export all run inside your browser tab. Image pixels and filenames are never sent to GeminiLogo.com — there is no upload endpoint to send them to, which you can confirm in your browser's network panel.
No. This Gemini watermark remover handles the visible corner logo only. SynthID is an invisible watermark spread through the image data itself, and this tool makes no claim to remove or weaken it — anyone can still paste your image into Gemini and ask.
No such promise is made. The tool reverses a known alpha overlay without generative repainting, which is as close to the original as the math allows. Compression, resizing, or an unsupported watermark profile can leave visible artifacts — the exact before/after shows you either way.
Yes — static JPEG and WebP files open fine, but clean reconstruction depends on the actual pixels, not the extension. Recompressed inputs can leave faint artifacts in the corner. Best results come from original-quality Gemini exports, which are typically PNG files.
No. The preview is computed automatically in your browser, and the download saves exactly that file. If the local artifact check flags a risky-looking result, a warning appears next to the download button so you can inspect the before/after first. Nothing downloads automatically.
No universal legal answer exists. Editing images you generated for your own use is generally uncontroversial; problems start when you misrepresent AI work as human-made or breach a platform's disclosure rules. Only edit images you have rights to, and check the rules where you publish.
Open this Gemini logo remover in Safari, pick the image from your camera roll, confirm the corner, and save the rebuilt PNG — it is a web tool, so nothing installs. Current iPhone Gemini exports are 1408×768, a size added in August 2026 after testing a real export.
No. This tool reconstructs a single fixed region in still images only. Veo and Google Flow videos carry the watermark across every frame, and tracking it frame by frame is a different job than reversing one overlay on one PNG — so we do not claim it.
Not cleanly. Asking Gemini in a chat prompt to remove its own watermark re-renders the picture, so the sparkle disappears but the whole image drifts and fine detail softens. If you want a file without the mark from the start, generate through Google AI Studio or the API instead.
Generate through Google AI Studio or the Gemini API — their image output currently carries no visible sparkle — or use a tier where Google drops it. Our guide to getting Gemini images without the watermark compares every official route, what it costs, and what SynthID still records.
Three common causes: the file is a screenshot — re-sampling shifts the 48×48 region off the alpha map and leaves a ghost outline; the image was recompressed by a chat app or editor; or its size is not on the validated list. Start from the original Gemini PNG export.

The tool handles the pixels; these guides handle the decisions around them — what the watermark is, whether cropping is enough, how the reverse math works, and when to generate without the watermark at all. The Gemini logo remover above stays free, with no upload and no sign-up.
