Format Details
PNM
PNM (Portable Any Map) is an umbrella format encompassing the PBM (bitmap), PGM (graymap), and PPM (pixmap) Netpbm image formats. A PNM reader can automatically detect and decode monochrome, grayscale, or full-color images using the same code path. It is commonly used in Unix image processing pipelines and scientific computing environments due to its extreme simplicity and cross-platform portability.
JPEG
JPEG (Joint Photographic Experts Group) is the most widely used lossy image compression format in the world, designed for compressing natural photographic images. It achieves high compression ratios by discarding visual detail that the human eye is less sensitive to, typically reducing file sizes by 10× or more. JPEG is universally supported across every device and application, and remains the standard format for digital photography and web images.
