BMP File - opening and understanding

Did your computer fail to open a BMP file? We explain what they are used for and recommend software that we know can open or otherwise handle your .BMP files.

What is a BMP file?

A .BMP file is a Windows Bitmap file. The .bmp file extension is given to raster image files, also known as bitmap image files. These non-compressed image files contain a file header and the pixels of the associated bitmap.

The file header contained in the BMP file includes information about the size of the BMP file, the width, the height, the color options of the BMP image as well as information about where the bitmap pixels should be located within the grid.

BMP files can store 2D digital images of varying resolution, height, and width. These images can be both color images and monochrome images of various depths.
