About the PBM format
PBM — Portable Bitmap
PBM is the monochrome (black and white) member of the Netpbm family of portable image formats. It stores each pixel as a single bit, making it the simplest possible image format. PBM files can be stored as plain ASCII text or compact binary, useful for scripting and tools.
Common uses
- Monochrome image processing and analysis
- Fax image storage and conversion
- Scripting and command-line image workflows
- Intermediate format in Netpbm pipelines
About the ICO format
ICO — Windows Icon
ICO is the standard icon format for Windows, storing one or more images at different resolutions within a single file. Modern ICO files can contain high-resolution PNG-compressed images alongside traditional BMP frames for compatibility across all Windows versions.
Common uses
- Windows application and file type icons
- Website favicon (favicon.ico)
- Windows shortcut and executable icons
- Cross-resolution icon sets for Windows UI
