Average Image Color Finder
Calculate an image’s average RGB color from decoded pixels and download a matching color swatch.
Image Tool
One imageThe image is scaled to at most one million sampled pixels. Transparent pixels are weighted by their opacity.

What this tool does
The finder samples decoded pixels, weights each pixel by opacity, and computes the arithmetic mean of red, green, and blue channels.
Average channel = Σ(channel × alpha) ÷ Σ(alpha)
A single average describes the whole image; it is not the same as the most frequent or dominant color.
Supported formats
PNG, JPEG, and WebP work when the browser can decode them. Transparent pixels contribute according to their alpha value.

Tips for better results
- Crop irrelevant borders before analyzing.
- Use dominant-color analysis when you need a palette rather than one mean.
- Expect color-management differences between browsers and professional editors.
FAQ
Is average image color the same as dominant color?
No. Average color blends all contributing pixels, while dominant color looks for the most common color cluster.
How does transparency affect the average?
Partly transparent pixels contribute proportionally and fully transparent pixels are ignored.
Why does a colorful image produce a grayish average?
Opposing hues can balance each other when their channel values are combined.
Can I copy the average color as HEX?
Yes. The result shows both RGB and HEX values, and the downloaded PNG uses that color.
Does the tool analyze every pixel?
It analyzes a scaled copy up to one million pixels, providing a practical average without excessive memory use.
