What is the .iff File Format?

The term IFF stands for Interchange File Format, and is a generic container file format that was developed by Electronics Arts in 1985. .iff files may contain text, image, or audio.

.iff files come under the category of Audio Files.

Purpose of the .iff file format

The .iff file format was developed to facilitate easy transfer of data between software produced by various companies.

Structure of .iff files

.iff files contain sections of data. A section of data is referred to as “chunks”, and each chunk is defined by four-letter IDs.

Three main chunk types are:

  • FORM – This section of data specifies the format of the .iff file.
  • LIST – This section of data specifies the properties of the .iff file.
  • CAT – This section of data contains the rest of data.

Generally, the top-level structure of an .iff file contains the FORM chunk type. Each of the three chunk types may contain numerical, text, or raw data.
