Top 5 Methods to Convert Your AIFF Audio Files to MP3

As a casual user, you may be unfamiliar with the AIFF audio format. Actually, AIFF is still widely used for storing uncompressed audio data. It remains a popular choice for music enthusiasts and audio professionals who prefer lossless sound quality. I would like to talk about AIFF in this article, exploring its pros and cons, comparing it with MP3, and telling five effective methods to make the audio conversion from AIFF to MP3.

AIFF to MP3

Part 1. AIFF vs. MP3

AIFF (Audio Interchange File Format) is a lossless format developed by Apple in the 1980s. AIFF files can store uncompressed audio with all details of the source recordings. So, they are ideal for professional audio editing and high-fidelity listening. Because the audio data remains uncompressed, AIFF files are significantly larger than compressed audio like MP3. AIFF can be supported by many professional audio editors and high-end players.

MP3 is a lossy audio format that offers good quality with a smaller file size. Its audio data is compressed, and a little sound quality is lost. Compared with AIFF, MP3 is significantly smaller in size. MP3 files are ideal for sharing, storing, and transition. Moreover, they are widely used for online music streaming. Almost all devices, players, platforms, and editors support the MP3 format. Even though MP3 uses a compression method, you can control its quality by adjusting the bitrate.

Due to all audio data remaining in AIFF, its file size is large. You need to turn AIFF files into MP3 for saving storage, especially when managing a large music library. While many audio editing programs support AIFF, you may still get some playback or compatibility issues. Converting AIFF to MP3 helps to get supported by more devices and players. Generally, you want to convert AIFF to MP3 for these two reasons.
