The PNM file format is an image file format used to store raster images in a simple binary format. Their simple format has made PNM an ideal format for certain tasks; however, due to the uncompressed nature of the format, PNM files can become very large at higher resolutions.

The format stores image pixel data as a sequence of bytes and does not use any compression, meaning there is no loss in quality when saving an image in the PNM format.

PNM files are a legacy file format that can be opened with certain image editing applications that still support this format; alternatively, we have a set of PNM image conversion tools designed to convert PNM files to other, more modern formats, such as PNG.

A JPG file is a compressed and highly efficient image file format whose aim is to store photographic-quality images using a fraction of the storage space compared to other lossy and non-lossy image compression methods available at the time.

The compression used by JPG encoders is "lossy", meaning image colors that are not perceptible to the human eye are discarded during the compression process. The removal of this color data greatly reduces the size of the final JPG file with no discernible loss in quality.

Due to their compact and high-quality format, JPG files are one of the primary image formats used by websites, digital and phone/tablet cameras, and more. This widespread support means JPG files can be edited within most popular image editing software.
