WHY CONVERT
Why convert AIFF to WAV
02
Broader cross-platform support
WAV is accepted by a wider range of audio players, car stereos, and streaming services than AIFF. The conversion removes a recurring compatibility friction without changing what the file actually contains.
03
Lower storage and bandwidth cost
WAV files are typically smaller than their AIFF counterparts, which reduces hosting, transfer, and storage costs at scale. The savings compound when serving the same content to many recipients.
