How to open file with .PGM extension?

Don’t you know what program to use to convert the .PGM file? Do you want to convert a .PGM file into a different format? Below you will find helpful information.

File extension .PGM

Full Name Developer Category
Portable Graymap File Format N/A Raster Image Files
.PGM

PGM (Portable Gray Map Image) is a bitmap image format created by Netpbm, and represented by the .pgm file extension. It is an image format primarily used for grayscale images, and involves various image elements, such as pixel dimensions, color and color depth. PGM retains all information from the original file, so it can be used to save high fidelity versions of an image.

About PGM

The PGM format is an 8-bit (modal) gray scale image created with Netbpm software. It provides options for using monochrome (black & white) images, single or multiple channels of gray, as well as multiple bit depth PGM images. The maximum number of pixels in an image is defined in the header section before the body data begins. Image compression is not supported in the PGM format; however, it does provide low complexity for viewing and printing.

Similar File Extensions

The following similar file extensions are also associated with portable gray map images: .pbm, .pgf, .ppm, and .pnm. Each of these formats use the same header structure and encoding system, making them simpler to store and manage than some other more specialized image formats.

After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .PGM) 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 .PGM 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 .PGM 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 .PGM 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 .PGM extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .PGM file. Sometimes you have to repeat the operation several times.

Other instructions

If none of the programs listed by us to work with the .PGM 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 .PGM file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .PGM file) will be extended to the maximum.

It is also good to check

  • if the .PGM file has no errors
  • or if it has been copied (or downloaded by the browser) thoroughly
In such a case it is best to try to download the .PGM file again from the same source on the Internet (or look for another source). If you received the file from another person, ask this person to re-send it. However, if the file was copied from some media, repeat the copying operation.
