About the BMP format
BMP — Bitmap Image File
BMP is an uncompressed raster image format native to Windows. It stores color data for each pixel individually without any compression, resulting in very large file sizes but perfect image fidelity.
Common uses
- Windows system graphics
- Intermediate file format for editing
- Print-ready artwork
- Legacy applications
About the PGM format
PGM — Portable Graymap
PGM is the grayscale member of the Netpbm family. It stores each pixel as a gray value (8 or 16 bits), making it ideal for grayscale image processing, scientific imaging, and intermediate conversion steps. Like PBM, it can be stored as ASCII or binary.
Common uses
- Grayscale image processing and analysis
- Scientific and medical image workflows
- Machine learning image preprocessing
- Intermediate format in Netpbm conversions
