How Color Palette Extractor works

Color Palette Extractor runs entirely in your browser. Extract dominant colors and export CSS/Tailwind palettes. Under the hood it uses Canvas 2D (the browser’s hardware-accelerated 2D drawing surface). Your files are read into this tab’s memory, processed on your own CPU, and handed back to you as a download. Nothing is sent to a server.

How to use Color Palette Extractor

1. Open Color Palette Extractor.
2. Adjust the controls. The preview updates in real time.
3. Fine-tune values until it looks right.
4. Copy the generated code or export the asset.

Tips

• Generated CSS works in every modern browser.
• Exports are produced locally, so you can work offline.

Color Palette Extractor FAQ

Are my files uploaded?

No. This tool runs entirely in your browser tab. Files are read from your disk into memory and the result is generated locally.

Is it free? Are there limits or watermarks?

Free and open source (MIT). There are no file-size caps, daily quotas, accounts or watermarks.

Does it work offline?

Yes, once the page (and any engine it needs) has loaded, it keeps working without a connection thanks to the service worker cache.
