The Resource Interchange File Format (RIFF), alternatively "Reverse IFF", is a wrapper or container format, originally developed by Microsoft and IBM. Formats based on the RIFF container include the widely used WAV (audio) and AVI (video) formats.

It is similar to IFF. One difference is that RIFF uses little-endian byte order.

See also RIFX.
