Convert JPG to PNM

Understanding JPG and PNM file formats

JPG (or JPEG) is a widely used compressed image format known for its efficient storage and compatibility with digital cameras, web, and mobile devices. It uses lossy compression, which reduces file size at the expense of some image quality.

PNM (Portable Any Map) is a family of simple, uncompressed image formats including PBM (Portable Bitmap), PGM (Portable Graymap), and PPM (Portable Pixmap). PNM files are often used in image processing and scientific applications due to their straightforward structure and lack of compression.
