World's simplest browser-based Portable Network Graphics (PNG) popular color mask generator. Just import your PNG image into the editor on the left, and you will instantly get a mask that shows the most common pixel colors on the right. In the options, you can choose how popularity is measured (find the most common pixel, top N colors, filter by count or percentage), decide how the mask is displayed, customize mask colors, preserve transparency, and view detailed pixel statistics. Free, quick, and very powerful. Created with love by team Browserling.

This browser-based utility generates a mask that highlights the most frequent pixel colors in a PNG image. Popular pixels are colors that appear more often than others. Their number can vary depending on the image size, optimization level, and color composition. In the options, you can choose how popular pixels are detected. You can find the single most common pixel color in the image – the color with the highest total occurrence among all pixels. Usually, there is only one such color (in PNGs with transparency, this is usually the transparent color), but in some cases, multiple colors may share the highest count. Alternatively, you can switch to a mode that detects the top N most frequent colors in the image. You can also define popular colors based on their usage count. For example, you can specify that only colors appearing more than 100 times should be selected. Another option is percentage‑based detection, where colors are included if they comprise at least a specified percentage of the image's pixels. Once popular pixels are identified, you can choose a mask mode for them. You can create a two-color mask that produces a binary result, where one color represents popular pixels, and the other represents non-popular pixels. Alternatively, you can generate a mask that replaces only popular pixels or only non-popular pixels with a selected color, while all other PNG pixels remain unchanged. If your PNG contains transparency and you want to preserve it in the mask, you can enable the alpha preservation option. This ensures that each pixel in the output mask keeps its original alpha value. The tool also provides precise pixel statistics, including the total number of pixels, the number of detected popular pixels, and the number of detected non-popular pixels. Png-abulous!

In this example, we detect the single most frequent color in the PNG image. The algorithm selects the color with the highest occurrence among all pixels. In this case, the most frequent color is full transparency (rgba(0, 0, 0, 0)), because the entire transparent background consists of identical zero-alpha pixels. We generate a two-color mask where popular pixels are displayed in black and all remaining pixels in white. (Source: Pexels.)
This example analyzes the color distribution of the PNG and highlights the 40 most frequent colors. The selected mask mode replaces only popular pixels with white, while all other pixels remain unchanged from the original image. This reveals how solid tones (like the teal background) and repeated patterns (such as the orange pulp) reuse pixels efficiently, while gradient areas (such as shadow transitions) use more unique colors. (Source: Pexels.)
In this example, we apply a count‑based rule, selecting colors that occur at least 1,000 times. The mask highlights non‑popular pixels in moccasin, while frequent colors remain unchanged. The result shows that large uniform regions (such as the car hood and the asphalt) contain many repeated colors, which typically indicates good image compression and color optimization.
