Sample BMP File Download

BMP is about as close to "raw pixels in a file" as an image format gets. Developed by Microsoft, it stores color data pixel by pixel with a simple header describing dimensions and color depth — no compression algorithm sits between the data and the file.

That directness means zero quality loss but large file sizes, which is exactly why BMP never took hold on the web, where bandwidth matters, but still shows up in graphic design tools, printing workflows, and situations demanding pixel-perfect, uncompressed output.

The sample below is a genuine uncompressed BMP, useful for testing an image library's raw pixel-reading logic without a compression algorithm changing the data along the way.
