BMP vs GIF Format Comparison

Aspect BMP (Source Format) GIF (Target Format)
Format Overview
BMP
Bitmap Image File

Uncompressed raster image format developed by Microsoft; stores pixel data directly.

Standard
GIF
Graphics Interchange Format

Lossless palette-based image format supporting simple animations.

Standard
Compression

No compression; stores full bitmap data.

Lossless LZW compression; limited to 256 colors.

Color Depth

1 to 24 bits per pixel, depending on variant.

8 bits per pixel, up to 256-color palette.

File Size

Large; uncompressed data size proportional to resolution and color depth.

Relatively small; depends on palette size and dimensions.

Advantages
  • Simple format structure
  • No quality loss due to compression
  • Easy to read and write by software
  • Wide browser support
  • Supports simple animations
  • Small file sizes for web use
Disadvantages
  • Very large file sizes
  • No compression means inefficient storage
  • No support for transparency or animation
  • Limited to 256 colors
  • No true alpha transparency
  • Not suitable for high‑color photographs
Use Cases
  • Legacy Windows applications
  • Simple graphics with limited colors
  • Software testing and debugging
  • Web graphics and simple animations
  • Icons and UI elements
  • Short looping animations
Tooling & Ecosystem
  • Microsoft Paint
  • Most image processing libraries
  • Windows-based viewers
  • GIMP, Photoshop, Paint
  • Browser-based editors
  • Animation tools like Ezgif

Why Convert BMP to GIF?

Converting BMP images to GIF significantly reduces file size and adds support for basic animations and web compatibility. While BMP stores raw pixel data without compression, GIF uses LZW compression to optimize storage, making images faster to load and share online.
