AIFF is a format developed by Apple in the late 80s for storing uncompressed, high-quality
audio. It is used in professional sound recording and post-production, but in everyday life it is
often inferior to the more universal and “lightweight” MP3. According to Descript, MP3
remains the most popular audio format in the world, supported by almost all multimedia
devices.
So why convert AIFF to MP3? The reasons are simple: saving space, compatibility with most
players, and convenience for everyday use. Below we will consider 7 effective ways to do
this, including popular desktop and online tools.
What is the difference between AIFF and MP3?
AIFF format: quality advantage
AIFF stores audio in uncompressed form, similar to WAV. One 1-minute file in CD quality
takes up about 10 MB. Used by professionals in sound recording, due to the purity of the
signal and the absence of losses.
MP3 format: the advantage of versatility
MP3 uses lossy compression, reducing the file size by 5-10 times. Almost all devices,
including old players and car radios, “understand” MP3.
Why is it important to choose the right converter?
Incorrect conversion can affect the sound quality, metadata and even lead to volume
distortion. The best converters allow you to:
❖ Adjust the bit rate (recommended for MP3 – 192-320 kbps).
❖ Work with batch file processing.
❖ Save metadata (title, artist, cover, etc.).
