BMP File Format FAQ
BMP (.bmp) is a simple, uncompressed raster format historically associated with Windows. It supports multiple bit depths and optional palette tables. Use sample .bmp files to validate raw pixel imports, bit-depth handling, and palette decoding.

BMP File Format FAQ
What is BMP mostly used for?
BMP appears in 1 category workflows across this library and is commonly used in image pipelines.
How should I test BMP handling in CI?
Start with the category-specific hubs above, fetch fixture manifests, then validate parser behavior across multiple file sizes and MIME signals.
Which related pages should I review before selecting BMP?
Use the related comparison, best-format, and conversion links on this page to evaluate tradeoffs and migration paths.
Why would anyone use BMP over PNG?
BMP is uncompressed and trivially simple to parse — no decompression, no chunks, predictable byte offsets. It is used in embedded systems, print drivers, and legacy imaging pipelines where simplicity matters more than file size.
What bit depths do the BMP samples cover?
Samples include 1-bit, 8-bit (indexed), 24-bit RGB, and 32-bit RGBA variants. Bit depth determines palette size and channel layout — parsers that assume 24-bit will fail on 8-bit indexed BMPs.
