PGM

The Portable Gray Map (PGM) format is a simple, portable image file that represents grayscale images. It is part of the Netpbm format family, suitable for easy manipulation and conversion. PGM files store pixel intensity values in plain text or binary, ensuring broad compatibility across various platforms and applications. Ideal for graphic designers and developers looking for a straightforward approach to grayscale image processing.

PPM

The Portable Pixmap Format (PPM) is a simple and widely-used image file format that stores pixel data in a human-readable format. Ideal for basic graphics applications, PPM files support RGB color encoding and are versatile for both software developers and graphic designers. Despite larger file sizes compared to compressed formats, PPM's simplicity makes it a preferred choice for image manipulation and teaching digital imaging concepts.
