What is a PGM file?
PGM (Portable Graymap) is a grayscale image format that stores pixels as plain text or binary values. It's part of the Netpbm family and is used for scientific and academic purposes where simple formats are preferred.
PGM is ideal for storing black-and-white or grayscale data in a human-readable or compact form.
How to open PGM files
PGM files can be opened with GIMP, IrfanView, ImageMagick, and many other graphics tools. Most Netpbm utilities also support conversion to other formats.

What is a JPEG file?
JPEG is one of the most widely used image formats in the world. The name comes from the Joint Photographic Experts Group, which developed the standard in the early 1990s. JPEG files use lossy compression to reduce file size while maintaining acceptable image quality.
They are ideal for photos and web use but not for images that need frequent editing or high precision, as repeated saves degrade quality.
How to open JPEG files
JPEG files are universally supported. You can open them on any device — computer, tablet, or phone — with built-in apps or web browsers. Most photo editors also support JPEG natively.
If you want to convert JPEG to another format or resize it, AnyConv offers a fast and easy solution directly online.
