How it works

Three simple steps

1

Upload your file

Drag and drop or click to upload an image or MP4 with a Gemini, Veo, Imagen, Nano Banana, or Google Flow watermark.

2

Reverse alpha blending

Click "Remove Watermark" — the algorithm detects the sparkle and uses the mathematically exact inverse of the blend Google applied to recover the original pixels.

3

Download clean result

Download the cleaned image or MP4. Resolution, frame rate, bitrate, and audio are preserved. Nothing was ever uploaded — your files stayed on your device the whole time.

Frequently asked questions

Yes. All processing happens directly in your browser using Web APIs. No files are ever uploaded to any server. Your images and videos never leave your device.
We support PNG, JPG, WEBP, and GIF for images. For video, MP4 files with H.264 encoding are supported. Auto-detection works best at 1280×720, 720×1280, 1920×1080, and 1080×1920; other resolutions can be cleaned with the manual watermark marker.
Yes. The video pipeline detects and removes the visible Gemini, Veo, and Google Flow sparkle on every frame. Audio is preserved bit-for-bit.
No. SynthID is an invisible pattern baked into every pixel by Google DeepMind. This tool only removes the visible sparkle logo. SynthID detection requires Google's own verification tools.
Yes. Nano Banana, Imagen, and Gemini all stamp the same sparkle watermark in the corner. The detector auto-handles all three and both 48×48 and 96×96 sizes.
Video processing uses the WebCodecs API, which is currently only available in Chromium-based browsers (Chrome, Edge, Brave, Opera 94+). Image processing works in every modern browser.
Removing the watermark from content you generated yourself is fine. Do not use this tool to strip watermarks from copyrighted material you do not own. This site is not affiliated with Google.
Older Gemini exports use a 48×48 sparkle; newer Gemini 2.0 Flash exports use a 96×96 sparkle. The tool auto-detects which size is present and applies the matching reverse alpha-blend.
On August 14, 2026 Google added a Media Watermark toggle inside Gemini that lets users turn the visible sparkle off for new generations. Old files, and exports from third-party tools, still need cleaning — that is what this tool is for.
Yes. The tool is completely free, no signup, no quota. The watermark removal algorithm runs entirely in your browser.
The web tool processes one image or one video at a time. For bulk workflows, the open-source Node.js library and CLI in the project README can handle folders.
No. Reverse alpha blending restores the original pixel values mathematically, so outside the watermark zone every pixel is byte-identical to the source. Image resolution, video frame rate, bitrate, and audio are preserved.
