The extractor downsamples a working copy, ignores mostly transparent pixels, and groups nearby RGB values with deterministic weighted clustering. Each result shows the cluster's estimated share of sampled pixels. Unlike an exact-color histogram, this method combines small shading and compression differences into useful visual groups.

What is an image color palette extractor?
An image color palette extractor finds several representative colors in a photo, logo, or screenshot. Add an image, choose between three and eight colors, then copy individual HEX values or the whole palette as CSS variables. Analysis runs in your browser, so the original image is not uploaded.
How to use
- 1Add an image. Drop a supported raster image into the tool, choose one from your device, or load the built-in example.
- 2Choose a palette size. Select three to eight colors. The palette updates from the same local pixel sample without uploading the image.
- 3Copy the colors. Copy one HEX value or copy every extracted color as ready-to-paste CSS variables.
Who it's for
- Brand designers can turn a logo or campaign image into reusable color tokens.
- Web developers can copy a photo's palette directly into CSS custom properties.
- Content creators can match text, backgrounds, and graphics to a thumbnail or social image.
- Illustrators and photographers can inspect how much of a composition each main color occupies.
FAQ
Is my image uploaded?
No. Your browser decodes the file, draws a smaller working copy to Canvas, and analyzes its pixels locally. This tool does not send the image or extracted pixel data to a server.
Is the image color palette extractor free?
Yes. You can extract palettes and copy every result without an account, payment, watermark, or per-image credits. The file stays on your device while you use the page.
What image limits and formats are supported?
You can choose PNG, JPG, WebP, GIF, AVIF, or BMP files up to 25 MB and 40 megapixels when your browser supports the format. Animated files use the frame rendered during browser decoding, so a still image gives the most repeatable palette.
How are colors extracted from an image?
The tool downsamples the image, ignores pixels below the transparency threshold, builds a compact color histogram, and runs deterministic weighted k-means clustering. Cluster averages become the palette, ordered by their estimated share of the sampled image.
Why does the palette change when I choose more colors?
Each palette size asks the clustering method to divide the same pixels into a different number of groups. With more groups, broad colors can split into lighter, darker, or more saturated shades. Fewer groups produce a simpler summary.
Why does another palette tool show different colors?
A color palette is an estimate rather than stored image metadata. Tools may use median cut, octrees, k-means, different color spaces, or different sample sizes. Transparency, cropping, animation frames, and color-profile handling can also alter the result.
Can I use the extracted palette in CSS?
Yes. Select Copy CSS to get a :root block containing one custom property per color. You can paste the variables into a stylesheet and rename them for semantic roles such as background, accent, or text.
