What is PNM file?
The .PNM file extension is used to store Portable Any Map image files. This type of graphic format is a convenient way to save, share, and transfer bitmap graphics efficiently without needing a specific operating system or image editing program. Developed by Jef Poskanzer at the University of California in the 1980s, it is supported by various Unix, Mac OSX, and Windows operating systems. The PNM format can store both 1-bit black and white images as well as 24-bit color images. [ ⏩ ] PNM file extension
What is BMP file?
The .BMP file extension is a raster graphics file type used to store bitmap digital images. Bitmap images are made up of individual pixels – each with its own specific colour value. These images are ideal for high-resolution graphical elements such as logos and line drawings because they can be scaled to any size without losing any of the image's visual fidelity. Due to the large file sizes, BMPs are best used for illustrations or web site graphics that are only displayed at a certain size. [ ⏩ ] BMP file extension
Software, that you can use to convert
How to convert the file from PNM to BMP?
To successfully convert the PNM file to BMP, you should install one of the applications from the list. After installing the software, open the program and select the file you want to convert (file-name.PNM). The next step is to select the target format from the list, in this case BMP (usually converters allow you to convert to several different formats, so check out their features - maybe one of the available formats will suit you more than BMP).
What is a file conversion?
A data conversion is normally an automated process to some extent. The effect of the operation of one program is automatically the input product of another application. If that does not happen we need to help the process a little bit and convert the file on our own, e.g. PNM to BMP. To obtain a matched structure of the data, it is necessary to use an appropriate converter.
Program for converting PNM files to BMP files is a kind of a "binary code translator" compensating for the differences in the code or translating it in such a way so that another application could use it. For us, as users, the visible change will be only another file extension. (After converting the file, it will be the extension BMP, while before this step we had the PNM file). For the programs, the difference is on a much higher level – either the application will be able to open a new BMP file, or not.
