How it works inside
The sample's longest side is limited to 160 pixels.
Equal-frequency colors are sorted by HEX for stable output.
Questions and answers
Is the file uploaded?
No. Decoding, Canvas sampling, and quantization run in the browser.
Does the palette contain every image color?
No. It is a bounded downsampled palette, so small details may be omitted.
