PPM (Portable Pixmap) is an image format developed by Jef Poskanzer. It contains human-readable text with an image header and body. Usually, the header includes the image contents such as the maximum color value, number of rows and columns, and the P3, which defines the image format. The image body, on the other hand, entails the actual picture data in a series of RGB values.
JPG, sometimes called JPEG, is a standard image format developed by the Joint Photographic Experts Group. JPG uses a high degree of lossy compression to give it a small file size while sacrificing the overall image quality. It can achieve up to an impressive 10:1 compression algorithm. Today, it’s the most widely used image format, thanks to its seamless compatibility with the World Wide Web and most image viewing and editing apps.
