BMP vs JPG

BMP vs JPG

BMP (Bitmap) is a legacy Microsoft Windows image format that stores image data completely uncompressed. JPG uses advanced math to compress images into a fraction of the size.

BMP JPG

Advantages

  • • Zero compression artifacts
  • • Exact pixel-for-pixel representation
  • • Simple to decode programmatically

Disadvantages

  • • Astronomically large file sizes
  • • Not suited for the internet
  • • Lacks modern features (transparency/metadata)

Advantages

  • • Highly compressed (90% smaller than BMP)
  • • Standard format for the web
  • • Supports EXIF metadata

Disadvantages

  • • Lossy compression artifacts
  • • Not pixel-perfect

The Verdict

JPG

When to use BMP

Use BMP only when working with legacy Windows software or simple embedded systems that cannot decode complex compression.

When to use JPG

Use JPG for virtually everything else, especially for storing photos or sharing images online.

More Format Comparisons

SVG vs PNG

SVG is a vector format made of mathematical paths, while PNG is a raster format made of a grid of pixels. This fundamental difference determines how they scale and where they are used.

WebP vs GIF

Animated WebP compared to traditional GIF.

WebP vs JPG

WebP was designed specifically to replace JPG on the web. It uses predictive coding to encode images, resulting in smaller files than JPG at the same perceived quality level.

PNG vs SVG

Compare pixel-based raster graphics (PNG) with math-based vector graphics (SVG).
