Free Color Extractor From Image — No Upload, No Account, No Limits
Table of Contents
Most color extraction tools upload your image to a server. That means your photo, logo, or design file travels to a company you have never heard of, sits on their server, and may be retained for analytics or model training. For brand assets, client work, or any confidential image, that is not acceptable. Here is why local processing matters and how to extract colors without uploading anything.
Why most color extraction tools upload your image
Server-side color extraction was the standard approach for years because browser-based image analysis was too slow for large files. A photo uploaded to a server could be processed by a powerful backend and returned as a palette in a second or two.
Today, HTML5 Canvas gives browsers the ability to read every pixel of an image locally — no server required. A modern browser processes a high-resolution photo in under two seconds, locally, with no data sent anywhere. Tools that still upload to a server are either outdated or have business reasons to collect that data.
How local color extraction works in your browser
The Kingfisher Color Extractor reads your image using the HTML5 Canvas API. When you drop or select a file, the tool draws it onto an offscreen canvas and samples pixel values across the entire image. A clustering algorithm groups similar colors to find the eight most dominant ones.
All of this runs in your browser tab — the file never leaves your device. No account is required. There is no file size limit because processing is local.
Supported formats: any image your browser can render — PNG, JPG, WebP, GIF, BMP, SVG, and more.

Each extraction produces:
- 8 dominant colors — shown as color swatches with HEX and RGB values
- Click-to-copy — click any swatch to copy its HEX code to your clipboard
- Pixel picker — click anywhere on the image to identify the exact color at that pixel (HEX and RGB)
- Export CSS — downloads all 8 colors as CSS custom properties
- Export Tailwind — downloads the palette as a Tailwind config object
There is no signup, no watermark, no "premium tier" that gives you more colors. Eight dominant colors covers the vast majority of design, branding, and web development use cases.

Extract Colors FreeFrequently Asked Questions
Is there a file size limit for the color extractor?
No. Since processing happens locally in your browser rather than on a server, there is no file size limit imposed by the tool. Very large files (above 20MB) may take a few seconds to process depending on your device's speed.
Can I use this tool without an internet connection?
Once the page loads in your browser, the color extraction runs entirely locally. If you save the page or use it from cache, it should continue working offline.
