What is a PNM file?
PNM (Portable Anymap) is a meta-format that can represent PBM (bitmap), PGM (grayscale), and PPM (color) images. It's part of the Netpbm format family and often used in academic and Unix-based systems.
PNM serves as a simple, low-overhead format that’s easy to manipulate with scripts and command-line tools.
How to open PNM files
PNM files can be opened with ImageMagick, XnView, GIMP, and Netpbm tools. They’re best used in environments that handle raw or uncompressed image data.

What is a JPG file?
JPG (or JPEG) stands for Joint Photographic Experts Group, the team that created the standard back in the early 1990s. It’s one of the most common image formats in the world, known for compressing digital photos while retaining acceptable quality.
JPG uses lossy compression, which means some image data is discarded during saving. This makes JPG files smaller, ideal for web use, email, and social sharing — but less ideal for images that require fine detail or multiple edits.
How to open JPG files
JPG files can be opened on virtually any device — Windows, macOS, Android, iOS, Linux — using default apps like Photos, Preview, or third-party software such as Photoshop and GIMP. Even web browsers can display JPGs natively.
This universal support makes JPG the go-to format for photography, online graphics, and digital documents.
