FileHint

image/bmp

The MIME type for Windows bitmap images. Uncompressed, hence bulky.

Typical extensions

Primary uses

  • Storing raw image data on Windows
  • Initial save of screen captures
  • Interop with legacy software

In a browser

Every major browser renders BMP. Bad choice for network delivery due to size.

On a server

CDNs typically transcode BMP to PNG or WebP on the edge for efficient distribution.

In email

Inline rendering works, but prefer PNG for any serious attachment.
