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.
PNG
PNG (Portable Network Graphics) is a widely-used lossless raster image format created as an open, patent-free alternative to GIF. It supports 24-bit color, full 8-bit alpha channel transparency, and highly efficient lossless compression. PNG is the preferred format for images with sharp edges, text overlays, logos, and any content where pixel-perfect lossless quality is essential, and it is universally supported in every browser and application.
