FAQ
H4 to IFF Conversion
What are H4 files?
H4 is a file extension used for HDF4 (Hierarchical Data Format, Release 4), a general-purpose format for scientific data created at the National Center for Supercomputing Applications (NCSA) in the United States and now maintained by The HDF Group. A file works as a container in which many kinds of data are stored together with descriptions of what they are: large arrays of measurements, images with color palettes, tables, and notes. Because it is independent of the computer that created it, it became a favorite of researchers. In 1993, NASA chose HDF4 as the format for data from its Earth Observing System, and satellite products such as those from the MODIS instrument were distributed in it for many years. The same files often use the .hdf extension.
What are IFF files?
IFF is an old image format associated with Amiga computers — a brand connected to Commodore, which used to be popular in the 1980s and 1990s. Commodore was one of the first types of personal computers to gain wide popularity among home users. An IFF file most likely contains an image that was created or edited using an image handling program on an Amiga computer. IFF files are currently considered obsolete and uncommon, so opening them with regular image viewers might be difficult.
