Бесплатный онлайн конвертер PFM в VIPS

This is a graphic file format that supports HDR. It is used for exchanging graphics data between applications. It is also used for development in the Netpbm suite of graphics editors. A PBM image has either a per-pixel RGB structure or instructions for representing grayscale tones.

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.
