PPM is a simple format for storing images portable pixmap: color (PPM), grayscale (PGM) and black and white (PBM). These formats can provide an intermediate representation of the data when converting raster image files listed three types between different platforms. PPM format was developed by Jeff Poskanzerom.

VIPS is a format used by libvips internally for calculation but it can also be used for storing images. It is simple, fast and has no size limit. However, only a few other programs are able to open such files which is why it is better to convert them to a more popular format.
