Portable Bitmap Format | N/A | Raster Image Files |
A .PBM file is the native file format for the Portable Bitmap Graphics (PNM) image file family. It is a "portable" variant of the binary encoding of a bitmap used in Unix/Linux systems. A PBM contains a single, binary-encoded 1-bit bitmap and can also store ASCII information in its header. It is used for storing black and white photographs or pictures created on a computer system. The PBM is one of the earliest bitmap image formats created and it is supported by most image processing software applications and web browser programs.
Similar File Formats
In addition to the PBM, the PNM also supports a number of similar file extensions, including: .PPM, .PGM, .PNM, and .PFM. They all contain some form of bitmap encoding, but differ slightly in terms of their encoding methods. For example, the.PGM extension is an 8-bit indexed image format, while the.PPM extension is a 24-bit RGB color format.
Comparing to Other Image Formats
The PBM format offers several advantages over other bitmap image formats. Compared to raw bitmap formats (RGB or RGBA), it often has a smaller file size and is more portable due to its simple binary-encoded format. When compared to other lossless image formats, such as PNG or GIF, the PBM offers faster processing speeds and simpler coding due to its lack of compression techniques.
Notable Applications Supporting the PBM Format
The PBM format is widely supported by all major image processing software applications, such as Adobe Photoshop, GIMP, and XnView. In addition, many web browsers support this format, including Google Chrome, Firefox, Microsoft Edge, and Safari. Knowing these notable programs that natively support the.PBM format will allow you to easily open, edit, and view your.PBM files.
Programs for WINDOWS system
Programs for MAC system
Programs for LINUX system
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .PBM) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .PBM extension.
When choosing the software we can select the system to use this software every time.
Remember!
Using it for the first time it is good to check whether the .PBM file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .PBM extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .PBM extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .PBM file. Sometimes you have to repeat the operation several times.
Other instructions
If none of the programs listed by us to work with the .PBM file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .PBM file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .PBM file) will be extended to the maximum.
It is also good to check
- if the .PBM file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
