PBM files can be confusing to handle because they are not one of the commonly used formats. If you have come across one, don't worry!
This article will tell you everything you need to know about it. I will explain exactly what this file is. You will also learn how to open PBM file in a simple way. I will show you the tools to get the job done easily.
Let's start our little journey together!
Part 1. What Is a PBM File?
A PBM file is called a Portable Bitmap file. This file was created in the late 1980s by a person named "Jef Poskanzer." It is a very basic image format for black and white pictures. This format saves an image without making it smaller.
The simple design makes it easy to change these files. PBM files are often used in image processing tasks, especially when converting between different formats.
PBM files come in two different types. The first is ASCII, which is also called P1. It is a plain text file. It uses a grid of zeros and ones to show the image.
The second type is Binary, also known as P4. This format is more compact for storing data. This makes it faster to save and work with files. These files are often found on Unix computer systems and begin with a special code, called a "magic number," which tells software what type of PBM file format it is.
