  1. 01

    Choose the original export

    Use the original Gemini, Veo, or Flow file. Cropping and recompression can make the sparkle harder to detect.

  2. 02

    Clean on your device

    Choose your file and start cleanup. No account, credits, or upload is needed. Keep this tab open.

  3. 03

    Preview and download

    Review the result before downloading. Save it before closing or refreshing this page; it is not stored in Library.

Clean before cropping or resizing

The cleaner looks for the visible Gemini sparkle in the image. Start with the original download. Cropped, resized, or repeatedly compressed copies can change the mark enough to make detection unreliable.

Choosing PNG for the result

Cleaned images download as PNG at the input resolution. A PNG can be larger than a source JPEG; this does not add detail. If you need a smaller JPEG for publishing, convert after reviewing the cleaned PNG.

Supported files

Use PNG, JPG, or WebP images up to 20 MB and 16 megapixels. For up to 10 images at once, use batch cleanup on the homepage. Download individual PNGs or a ZIP.

Review your result

Cleanup quality varies with the export. Some traces may remain. Unmark targets the visible sparkle and does not remove invisible SynthID signals.
