About the PNG format
PNG — Portable Network Graphics
PNG is a lossless image format that supports transparency (alpha channel). Created as an open alternative to GIF, it is the preferred format for web graphics, logos, icons, and any image that requires crisp edges or transparent backgrounds.
Common uses
- Logos and icons with transparency
- Web graphics and UI elements
- Screenshots
- Images requiring precise color accuracy
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
