When working with digital images, scanning documents, or using classic software like Microsoft Paint, you will often encounter files ending with the .bmp extension.
In computer graphics, the full form of BMP is Bitmap Picture or Bitmap Image File.
Full Form: Bitmap Picture or Bitmap Image File.
Structure: Creates an image using a grid of individual colored pixels.
Compression: Uncompressed, meaning no data is lost.
File Size: Very large compared to modern image formats.
Creator: Originally developed by Microsoft for the Windows operating system.
A Bitmap is one of the oldest and simplest digital image formats. The word perfectly describes how the image is created. Imagine a massive grid of thousands of tiny squares (like graph paper). Each tiny square is called a 'Pixel'. The BMP file format literally maps out the exact color of every single pixel on that grid. When you zoom out, the grid of colored dots forms a complete picture.
BMP is generally an uncompressed image format. This means it saves the exact color data for every single pixel individually without using any mathematical tricks to shrink the file size. As a result, a BMP image boasts incredibly high, loss-less quality (it looks exactly the same no matter how many times you save it). However, this makes BMP files massive in size compared to modern formats. A single high-resolution BMP photo can take up 30 to 50 Megabytes of storage.
Because of their massive file sizes, BMP files are almost never used on websites, as they would take too long to load. Instead, the internet uses JPEG (which heavily compresses the image to reduce file size but loses some quality) or PNG (which offers compression and supports transparent backgrounds, which BMP does not).
In computing, BMP stands for Bitmap Image File or Bitmap Picture.
BMP is an uncompressed format that saves exact pixel data, resulting in extremely high quality but massive file sizes. JPEG is a compressed format that reduces file size significantly by sacrificing a small amount of image quality.
Websites avoid BMP files because their massive, uncompressed file sizes would consume too much internet data and cause web pages to load incredibly slowly.
