- Download or copy CSS variables, PNG palette and verify it in the destination application, browser, viewer or workflow that will actually use it.

How it works technically
Raster image operations work on decoded pixel data. Dimensions, alpha transparency, color representation and encoder settings can all affect the result independently.
Representative-color extraction summarizes many source pixels into a smaller set of colors. The result depends on sampling/quantization and is not a list of every unique pixel.
Common use cases
- Build a website color palette from a photo
- Extract brand inspiration colors
- Create CSS variables
- Save a visual palette reference
Choosing the right settings
- Choose fewer colors for a concise design palette and more colors when the image has meaningful secondary tones.
Common problems and fixes
A small accent color is missing
Increase the palette color count; dominant-color methods can ignore colors that occupy only a small area.
Browser processing and privacy notes
The source code for this build performs the documented file transformation or analysis from browser JavaScript/Web APIs, and the video tools load FFmpeg.wasm for media processing. The site also contains third-party analytics, font/CDN and advertising scripts that can make ordinary network requests. Therefore, the precise claim made here is limited to the tool routine: it does not need a separate AutoClip file-upload API in order to perform the documented local operation.
For sensitive files, you should still use your browser’s developer tools or network controls if you need to independently verify the behavior of every third-party request in your environment.
