With this online program, you can convert the given JPEG picture into a binary JPEG. A binary picture, also known as a two-level, bi-level, or 1-bit picture, is a picture that uses only two colors. Such pictures are often created as pixel art and each pixel is stored as 0 or 1. Usually, the two colors are black and white but in this tool, you can set any two custom color tones. The process of converting a picture to binary is called binarization and it can be done in multiple ways. The first method uses a color quantization algorithm that finds the two dominant colors in a picture and by calculating the difference in hue, all pixels take one or the other color value (whichever is closest). The second type of binary picture uses color dithering. The dithering algorithm uses dot density patterns to paint the shapes, borders, and depths of objects in a picture. By filling dots more densely, shadows and darker areas are produced and by having a low concentration of dots, the white and light areas are displayed. This tool can automatically calculate the two dominant colors of any JPG and instantly display the picture in these two tones. Additionally, in the options, you can specify the two colors which should be used to create a binary JPG. The colors can be selected using a palette or specified by the name, hex, or RGB code. The "Enable Dithering" option lets you generate JPGs with dithering and you can switch between the 9 most popular dithering methods, including Floyd Steinberg, Stucki, and Sierra methods. Jpgabulous!
