What is an IFF file?
An .IFF file is primarily an Interchange File Format container. Electronic Arts created this standard for the Amiga computer system in 1985. The format stores different types of data, including images, text, and audio.
However, modern .IFF files often contain video game assets. The popular basketball game NBA 2K uses .IFF files to store 3D player models, textures, and courts. Some of these are standard ZIP archives wrapped in an .IFF extension. The classic game The Sims also uses .IFF files to store specific game logic and objects.
How to open IFF files?
Because the .IFF extension has multiple possible meanings, it is difficult to know exactly what your file contains. viewer.online/iff analyzes .IFF files to identify their exact format and creator software, shows which programs can open the file, and usually previews it.
Software and tools
If your .IFF file is an NBA 2K game archive, you can often extract it using standard compression software like 7-Zip or WinRAR. You might need to change the file extension to .zip first.
If your file is a classic Amiga image, you can view it using an image viewer like IrfanView or XnView. If you need to use this file in modern software, you should convert it. We recommend using convert.guru to convert .IFF image files into .PNG or .JPG formats, or .IFF audio files into .MP3 or .WAV.
Summary
viewer.online/iff directly opens and previews .IFF files in the browser, eliminating the need to install software or troubleshoot compatibility issues.
