- Description
- The Portable Bitmap (PBM) file format is a monochrome image format that is part of the Netpbm suite, which also includes Portable Graymap (PGM) and Portable Pixmap (PPM) for grayscale and color images, respectively. PBM files represent images as a collection of black and white pixels in a very simple, text-based or binary format, making them easy to read and manipulate with basic text editing or binary tools. The simplicity of the format allows for straightforward editing and conversion to and from other image formats, though it lacks support for color or grayscale nuances. Due to its simplicity and portability, the PBM format is often used in research, development, and applications where basic visual representation is needed without the overhead of more complex formats.
- It is an icon image file used to show application icons in the macOS Finder and macOS dock. It contains one or several .PNG images and it supports 1bit and 8-bit alpha channels.
