Image palette extraction
Deterministically extract up to 16 representative colors from local images, and output HEX, CSS variables, and JSON.
How to use the image palette extractor
The image palette extractor processes input only in the current browser; it does not upload, access the network, or save user data.
Input content
Select local images and set 2–16 colors.
Select a processing method
Fixed sampling and quantization algorithms ignore transparent pixels or use the specified background color.
Check and export
Copy the HEX and CSS variables, or download the JSON palette.
Limitations and Notes
- The palette is an approximate statistical result; gradients, transparency, and compression can affect the number of colors.
- Colors may vary across displays and color spaces; brand colors should still use the official color values.
- The tool only provides locally processed results; important configurations, secrets, documents, and published content must still be reviewed in the target environment.
FAQ
Will the input be uploaded to a server?
No. The page only uses browser memory, the local file API, and local resources already provided with the site.
Why isn’t the extracted color the one that appears most frequently to the naked eye?
The tool uses fixed sampling and quantization to ensure speed and reproducibility; the results are representative colors rather than subjective selections by a designer.
Why do the results still require manual review?
Edge-case syntax, regional standards, third-party readers, and target runtime environments may differ; the tool does not replace final validation.
