Bitmap Palette Extractor

World's simplest bitmap tool
This is a free and fast online utility that extracts a visual color palette from a BMP image. You can use the configuration options (below) to group similar tones or keep exact pixel colors, choose the number of swatches, and set the order in which they appear. Extra options allow you to display a hexadecimal or RGB code on each swatch, show the percentage of the image that uses each extracted color, and copy all palette codes as text. Created by graphics designers from team Browserling.

What is a Bitmap Palette Extractor?

learn more about this tool
This free online browser-based program finds the colors used in a BMP image and creates a clear palette from them. Instead of picking colors from the bitmap by eye, you can let the program count them and display the selected tones as stacked swatches in a separate image. You can extract colors in two ways. The average-colors mode gathers nearby shades into color families, which gives you a compact overview of the bitmap's visual character even when the image contains gradients, antialiasing, or photographic detail. The exact-colors mode keeps pixel values separate and reports the individual colors that occur most often, which is useful for inspecting icons, sprites, diagrams, and other artwork with a controlled set of tones. You can enter any palette length you need and arrange the result by pixel frequency, rainbow sequence, reverse rainbow sequence, rising lightness, or falling lightness. For identification, each swatch can stay clean or display its hexadecimal or RGB code. The percentage option shows how much of the image uses each extracted color, so you can quickly see which colors are common and which appear only a little. A text version of the finished palette is also placed in the options area so the codes can be copied directly into a stylesheet or drawing program. The generated palette can also be saved as a separate image. Bmp-abulous!

Extract an Average Bitmap Palette
In this example, we load a BMP image of a colorful tulip wreath on a bright yellow background and extract eight average color tones. The tool groups similar shades from the flowers, leaves, and background, and arranges the pink, yellow, brown, and green swatches in rainbow order. (Source: Pexels.)

Extract Exact Bitmap Tones
In this example, we find twelve exact pixel colors in a BMP photo of an icy lake and arrange them from lightest to darkest. The most common exact color is #ddebf4, yet it appears in just 0.36% of the pixels. Such small percentages show that the photo contains many distinct tones and smooth color transitions across the sky, snow, and ice. Each swatch includes its hex code and usage percentage.

Build a Compact Building Palette
In this example, we create a compact four-color palette from a BMP photo of a bright building facade. The turquoise wall, sandy yellow facade, and red door occupy similar portions of the image at about 28%, 27%, and 25%, respectively. Dark brown details appear a little less often at nearly 19%. The palette makes this balance easy to compare by printing each RGB value beside its percentage. (Source: Pexels.)
