What is a BMP file?

A BMP file (Bitmap Image File) represents one of the foundational raster graphics formats, originally developed by Microsoft in the mid-1980s as part of the Windows operating system. Built on the Device Independent Bitmap (DIB) specification, BMP was designed to provide a simple, straightforward method for storing digital images without the complexity of compression algorithms, ensuring perfect pixel-accurate reproduction of image data.

As an uncompressed raster format, BMP stores each pixel's color information directly, creating a complete digital representation of the original image without any quality loss. This approach results in larger file sizes compared to compressed formats, but guarantees that every detail, color, and pixel remains exactly as intended, making BMP the preferred choice for applications where image fidelity takes precedence over storage efficiency.

Technical Foundation

  • Device Independent Bitmap (DIB)
  • Little-endian byte ordering
  • Uncompressed pixel storage
  • RGB color space support

Format Specifications

  • .bmp, .dib (extensions)
  • MIME type: image/bmp
  • 1, 4, 8, 16, 24, 32-bit color depths
  • Optional RLE compression

Why Choose BMP Files?

BMP represents the foundation of digital image storage, offering unparalleled simplicity, universal compatibility, and pixel-perfect quality preservation. While modern compressed formats have advantages for web and mobile use, BMP remains the gold standard for applications requiring absolute image fidelity, direct pixel access, and maximum compatibility across all systems and software.
