PNM to WEBP Conversion: FAQ

What are PNM files?

PNM (Portable Anymap) is a generic format for the Netpbm pack, consisting of intermediary files used in the conversion process by a collection of open source programs called Portable Bitmap Utilities. PNM is used as a generic name for the 3 file formats which are part of this pack: PBM (Portable Bitmap), PPM (Portable Pixelmap) and PGM (Portable Graymap).

What are WEBP files?

WebP is an image file format released by Google in 2010 with the aim of challenging the leading positions of JPG and PNG in the domain of storing and transferring digital images. The purpose of the WebP format is to improve the speed of browsing by offering the same quality as JPEG or PNG, but in a smaller size. WebP images can contain both lossy and lossless compression. They continue, however, to be incompatible with some image viewers and browsers, and are often described by analysts as "work in progress" — a format that still needs to be developed.
