What happens when you convert AIF to AIFF
- AIF and AIFF are the same format with different extensions, so nothing is re-encoded. The file is copied byte for byte and saved with a .aiff extension.
- Because the bytes are identical, the AIFF has exactly the same quality, dimensions and size as the AIF.
How to convert AIF to AIFF online
- Press "Choose AIF files" and select one or more files, or drag them onto the box. You can add files of any size your device can hold in memory.
- Adjust the settings if you need to: the bitrate controls quality and size. The defaults suit most people.
- Press "Convert to AIFF". The first audio or video conversion downloads the converter engine, about 32 MB, which your browser then keeps for next time.
- Save each AIFF with its download button. Close the tab and every trace of the files is gone from memory.
Why convert AIF to AIFF?

About AIF and AIFF files
What is an AIF file?
AIF is the same format as AIFF with a three-letter extension, common in sample libraries that had to work on older Windows systems.
What is an AIFF file?
AIFF is Apple's uncompressed counterpart to WAV, holding the same audio with bytes stored in the opposite order. Unlike WAV it has a standard place for track names and artwork.
AIF to AIFF not working? Common problems
- The conversion is slow. Audio and container changes take seconds, but re-encoding video runs on your own processor. Lower the resolution to 720p, close other tabs, and keep the device plugged in.
- The tab stops or reloads on a very large file. Browsers limit how much memory one tab can use, around 2 GB and less on phones. Split long recordings or convert them on a computer.
- Song titles are missing. Tags such as title and artist are copied when AIFF can store them, but cover art is not carried over.
Convert AIF to AIFF with ffmpeg
This converter runs ffmpeg inside your browser. If you would rather use the ffmpeg command line on your own computer, this command produces an equivalent AIFF with the same kind of settings:
ffmpeg -i input.aif -vn -c:a pcm_s16be output.aiffReplace input.aif with the name of your file. For a whole folder of AIF files, run the command in a loop, or drop them all on the converter above, which processes them one after another.
