Online Image Color Extractor: upload an image to automatically extract the dominant colors and generate an 8-color palette with HEX values. Supports drag-and-drop and paste. Essential for design inspiration. All processing is done locally.
TL;DR: Free online image color extractor. Upload an image to auto-extract dominant colors into an 8-color palette with HEX values. Drag-and-drop and paste supported. Images processed locally, never uploaded.
For local tools, open DevTools → Network and search your input — it should not appear in requests.
Usage Guide
Extract dominant colors from an image locally for UI/docs palettes — approximate, not a print spectrophotometer.
1. Extract
Upload, review swatches, copy values.
- Upload.
- Review.
- Copy.
2. Bias
Compression/gradients skew clusters — trust brand specs first.
3. Next
Palette, contrast, and color-blindness tools.
- Crop subject.
- Prefer brand specs.
- Check contrast.
4. Transparency
Flat fill behind alpha before extracting if needed.
5. Performance
Downscale huge images first.
6. Rights
Only use images you may analyze; note sources.
FAQ
The extraction runs locally with no network involved, so the input itself has no leakage path. Still, only analyze images you have the right to use, and clean up local screenshots and temp files afterwards.
File picker, drag-and-drop, or pasting a screenshot straight in. Local analysis extracts the dominant colors into an 8-color palette with HEX values, each copyable in one click.
That is expected. JPG compression noise, large gradients, and white borders all skew the clustering; cropping to the subject first helps. For exact brand colors, defer to the design spec and treat extraction as a reference.
Transparent areas can be counted as a background color in the statistics. Flatten the image onto a white or black layer first, then compare which result matches your expectation.
They can — downscale oversized images before extracting. The dominant color distribution is usually unaffected and it is much faster.
A common chain: extend the palette with a palette generator, verify text readability with a contrast checker, then sanity-check distinguishability in a color blindness simulator.
