PGM (short for Portable Gray Map) is a file format associated with Netpbm, a bitmap graphics package. What do PGM files contain? PGM files store 8- or 16-bit grayscale images. A single PGM file can store multiple such images. Each pixel can take a value from 0 (black) to 65 536 (white).
JPEG file extension is commonly associated with image files, and is one the most popular graphic formats currently in use. It uses lossy compression algoritm designed by Joint Photographic Experts Group. JPEG files are usually used to hold digital image data and computer graphics.
After converting the file to the new format, you will be able to use other programs to support it. Keep in mind, however, that the PGM file after converting to JPEG may differ slightly from the original. The most important information should be kept, but if you want the file after conversion from PGM to JPEG to be the same, you have to do this carefully and choose the proper application from the list below.
There is no guarantee, of course, that the conversion will come up to all your expectations, but it will certainly help you. If, after all, the effect of converting PGM to JPEG does not meet your expectations, you can simply try to find on the Internet a different version of your file in PGM format, properly converted to a JPEG file by someone else. If this fails, use the information provided in the further part of the website.
If after converting the file PGM the desired result was not achieved, you can try to change the format of PGM file to other than JPEG. On our website you will find more information on the following conversion options
Unfortunately, if after performing the two previously described steps (trying to find your PGM file converted by someone else, and the attempt to convert it to JPEG on your own) you still have a problem with your file, then there are only a few solutions left. You can once again try to find and install an application that can open the PGM file in its original format (without conversion to JPEG file). Such a solution will be difficult to implement, but it certainly will give the best result.
