About This Tool
The average image color tool combines the analyzed pixels into one color for a quick impression of the overall tone. The average may not appear as an individual pixel in the original image.
How to Use
- Choose or drop in your image.
- Review the default linear-light average.
- Switch to simple RGB averaging if you want to compare the results.
- Check the analysis dimensions and copy HEX, RGB, or HSL.
Supported Formats
- PNG, JPG/JPEG, and static WebP images are supported. Choose or drop in one image at a time.
- Files can be up to 100 MiB, 40 million pixels, and 16384 pixels on either side. Large images need more memory, so choose a size that works well on your device.
Understanding the Results
- Linear-light averaging is the default: colors are converted to linear light, averaged with alpha weighting, and converted back to familiar color values.
- Simple RGB averaging directly averages the encoded red, green, and blue values. It is useful for comparison but can differ from the linear-light result.
- Fully transparent pixels are ignored, and other pixels are weighted by alpha. A fully transparent image shows a notice that there are no pixels to include.
Averaging and Sampling
- sRGB values are not proportional to light intensity, so a direct RGB average is often darker. Equal amounts of pure black and white give about 128 with simple averaging and 188 with linear-light averaging.
- Analysis uses up to 1,000,000 pixels, with a maximum side length of 2000 pixels. Large images are scaled down, and the actual analysis size is shown. Small images use all their pixels.
- An average combines all included colors. It does not replace a dominant color, which represents the most common color group.

FAQ
How is the average color calculated?
The tool averages analyzed pixels with transparency weighting. By default, it first converts colors to linear light; you can also switch to a direct average of RGB values.
How is average color different from dominant color?
The average combines all included pixels, while the dominant color represents the leading color group. The average color may not actually occur in the original image.
Are transparent pixels included?
Fully transparent pixels are excluded, and other pixels are weighted by alpha. If every pixel is transparent, there is no visible average color to calculate.
Why do simple RGB and linear-light averages differ?
Standard sRGB values are encoded nonlinearly, so they do not directly represent light intensity. Linear-light averaging accounts for this relationship and usually gives a brighter result for high-contrast combinations such as black and white.
