Is my image uploaded to a server?

No. Extraction runs locally in your browser; the image never leaves the device and dies with the tab.

Which formats are supported?

Bitmaps your browser can decode - JPG, PNG, WebP. Rasterize SVG vectors before uploading.

Pixel clustering by frequency, merged across near-duplicates - not random sampling.

Colors themselves aren't copyrightable; the photo's rights stay with its author, so clear the image license for commercial use.
