Convert BMP to BM

Understanding bmp and bm file formats

BMP (Bitmap Image File) is a widely used raster graphics image file format developed by Microsoft. It stores digital images independently of the display device, making it a popular choice for high-quality, uncompressed images on Windows systems.

BM is less commonly referenced as a standalone file format. In many contexts, BM is simply the file signature (magic number) at the start of a BMP file, indicating it is a bitmap. However, in some specialized software or legacy systems, a .bm file may refer to a raw or proprietary bitmap format. Before converting, ensure you know the target application's requirements for the .bm file.

How to convert bmp to bm

Since BMP and BM files are often structurally identical, you can usually convert by simply renaming the file extension from .bmp to .bm. However, if the target application expects a specific format or header, you may need a conversion tool that allows for custom export settings.
