A PNM file is an image file format used to store color images in a simple binary format and was used in many applications when it was first introduced.
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. The use of uncompressed binary does mean that PNM files can become very large at higher resolutions.

The ZIP file is one of the most common types of compressed file types available and is widely used to compress any file type and give great compression results, leading to smaller file sizes. ZIP files were originally released in 1989, and over time, the format has undergone many revisions.
ZIP archives can contain any number of folders and files and can use many different compression algorithms to perform the file compression, though DEFLATE is the most common one in use. The format has built-in support in many operating systems, including Mac OS and Microsoft Windows.
