BMP is a popular image format in the past. Now, when PC runs Window, BMP (Window bitmap) image is mainly used as wallpaper. Programmers sometimes use BMP images in their software help functions.

BMP can provide lossless compression, and the compression method is RLE (Run-length Coding), which is an excellent choice when creating wallpaper image files.

Sometimes, when looking for wallpaper pictures saved as RLE compressed files, there will be recognition errors in Window, so it is best to turn off RLE compression before using it.
