Overview
IFF (Interchange File Format) is a file format introduced by Electronic Arts on the Commodore Amiga computer. Its structure is similar to RIFF or PNG, using various self-contained chunks to contain different data.
Although IFF is most commonly used as an image format (using the file extension .iff
), it can actually hold a lot of different data types. Some examples of IFF files are
- ILBM Interleaved bitmap image
- XMI XMidi music files
- 8SVX audio sample data
- SX2 Propellerhead Reason NN-XT patches
- ANIM
Some other formats are largely or heavily influenced by the IFF standard, but are not compatible. These include, for example:
- Erlang BEAM compiled modules[1][2]: Uses 4 byte alignment instead of 2 byte, and the root chunk has a different ID (
FOR1
instead ofFORM
) - Microsoft's RIFF and RIFX formats are based on IFF (RIFF uses little-endian byte order instead, and the root chunk is called
RIFF
instead ofFORM
) - Apple's AIFF and AIFC formats are similar to IFF/RIFF as well
- Maya IFF
