Frequently Asked Questions
Learn more about pixel sampling, color quantization, and design exports.
How does the color extraction algorithm work?
FileFryer samples pixel data using HTML5 Canvas and groups similar colors using a 5-bit quantized color bucket algorithm. It filters out transparency and enforces minimum Euclidean color distances to ensure diverse, harmonious swatches.
Can I export the extracted colors directly into my code?
Yes! You can toggle between Raw Hex, CSS Variables (:root { --color-1: ... }), Tailwind CSS theme config objects, and structured JSON.
Can I pick a specific color that was not in the top swatches?
Yes! The Interactive Eyedropper allows you to click anywhere directly on your previewed photo to sample the exact color of that pixel.
Are my uploaded photos or branding assets stored on a server?
No, never. The image is drawn directly to an in-memory client-side canvas element. No bytes are transmitted over the internet or saved to remote disks.
Does this palette extractor work offline?
Yes! You can disconnect your internet and extract palettes from unlimited photos completely offline.
What image formats can I upload for palette extraction?
FileFryer supports all standard web raster formats including JPEG, PNG, WebP, GIF, and SVG. Transparent pixels are automatically excluded so they do not skew the dominant color calculation.
