What are BMP files and how to open them

Are you having problems opening a BMP file or are you simply curious about its contents? We're here to explain the properties of these files and provide you with software that can open or handle your BMP files.

What is a BMP file?

BMP files have multiple uses, and Windows Bitmap is one of them. Read more about the other uses further down the page.

Windows Bitmap

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.
