Free Gemini Watermark Remover
Remove the visible Gemini sparkle watermark from many images and videos at once, directly in your browser. De-Gemini uses known watermark profiles, automatic bottom-right detection and conservative pixel restoration.
⚠️ Important: results can vary by image.
Watermark removal may leave faint light/dark marks or affect nearby details,
especially on textured, bright, or high-contrast backgrounds. Always review
the processed result at full size and keep your original file. Use only media
you own or are authorized to edit. Processing happens locally in your browser.
100% browser-side
Images stay on your device. Video processing uses FFmpeg.wasm in the browser.

⚡ V3.2 bulk engineEvery file gets a full bottom-right corner search plus the known Gemini anchors. A match must clearly stand out from the picture's own texture, and detection ignores colour and brightness, so black & white, dark and crowded pictures are recognised like any other. Strength is calibrated per file, then the exact blend is reversed. Videos use the same reverse blend on every frame.

A Gemini watermark remover built for fast, local processing.
De-Gemini is a browser-based Gemini watermark remover for supported images and videos. Instead of asking you to upload the original media to a processing service, the tool performs the supported image workflow inside your browser.
The image engine searches for known Gemini sparkle watermark profiles using the image dimensions and bottom-right geometry. When a sufficiently confident match is found, the restoration engine applies the calibrated alpha profile only to the detected watermark region.
This design is intentionally conservative. If a confident watermark match is not found, the image is not modified. The goal is not to make an aggressive edit everywhere, but to preserve the surrounding image while restoring the detected watermark pixels.
Common Gemini image aspect ratios.
De-Gemini supports the common image shapes shown below. The detector uses the actual pixel dimensions rather than stretching the watermark profile to match the entire image aspect ratio.

Image and video formats.
The upload interface accepts common image and video formats. Image restoration exports a clean PNG, while supported video processing produces an MP4 result.
| Media | Input formats | Processing | Output |
|---|---|---|---|
| Image | PNG, JPG/JPEG, WEBP | Browser-side | PNG |
| Video | MP4, WEBM, MOV | FFmpeg.wasm in browser | MP4 |
Detect → calibrate → restore.
The image workflow starts by reading the selected image into a browser canvas. The detector evaluates known reference alpha maps against bottom-right candidate regions. Multiple dimensions and inset positions are considered for supported export families.
Once a candidate passes the confidence threshold, the engine estimates an appropriate restoration gain for colour images. Neutral and grayscale images retain the dedicated conservative calibration path from the established engine.
The final image correction is restricted to the detected square region. The rest of the image is not intentionally rewritten by the restoration pass.
Important limitation
De-Gemini targets the visible Gemini sparkle watermark represented by its
supported profiles. Removing a visible mark does not imply removal of
invisible provenance systems, metadata, or other watermark technologies.
Your selected image stays in your browser during image processing.
De-Gemini's image workflow is designed around local browser processing. The application does not need to upload the selected image to a custom De-Gemini image-processing server.
What the remover processes
The selected media, browser canvas pixels and temporary processing data needed to create the result.
What analytics should receive
Only product events such as page view, upload type, processing result and download. Media pixels and file contents are not sent as analytics event parameters.
Analytics is optional and controlled by the configured measurement ID. If the ID is left as the placeholder, no analytics script is loaded.
Frequently asked questions.
Tap any question to expand the answer.
Can I clean many files at once?
Yes. Select or drop as many images and videos as you like. They are processed one after another in your browser, and you can download each result or everything together as a ZIP.
What is a Gemini watermark?
In this tool's context, the Gemini watermark is the visible sparkle mark that can appear on supported Gemini-generated media. De-Gemini specifically targets supported visible profiles.
How do I remove a Gemini watermark from an image?
Select a supported image, let De-Gemini inspect the bottom-right watermark region, and press Remove Watermark. If a confident profile match is found, the browser performs the restoration and prepares a PNG for download.
Does De-Gemini upload my image?
The supported image restoration workflow is browser-side. It does not require your image to be uploaded to a custom De-Gemini processing server.
Which Gemini image ratios are supported?
The interface supports 1:1, 16:9, 9:16, 4:3 and 3:4 image ratios, along with custom dimensions that may match known detector families.
Does it work on black-and-white images?
Yes. The restoration engine includes a dedicated grayscale/neutral path designed to avoid the colour-image adaptive gain logic.
Can it remove invisible AI provenance watermarks?
No claim is made here that the visible sparkle remover removes invisible provenance systems. De-Gemini's supported target is the visible watermark profile.
What happens if the watermark is not detected?
The tool stops instead of applying a broad blind correction. This is an intentional safety measure for image quality.
Can I use De-Gemini on someone else's image?
Only use the tool on media you own or have permission to edit. Copyright, licensing and platform rules still apply to the underlying media.
