What happens when you convert AIFF to MP3
| Compression | Lossless → Lossy |
|---|---|
| Size per minute | AIFF ≈ 10.6 MB → MP3 ≈ 1.4 MB at 192 kbps |
| Quality | Lossy encode; 192 kbps is transparent for most listeners, 128 kbps is fine for speech |
| Tags | Title, artist and album tags are copied when the target format supports them |
| Opens in | every device, car stereo and audio app |
Sizes are typical values; your files will vary with content and settings.

Frequently asked questions
Will the MP3 lose quality?
MP3 uses lossy compression, so some fine detail is discarded to make the file smaller. At the default quality setting the difference is very hard to see. Raise the quality slider if you need the result to stay closer to the AIFF original.
Will the MP3 be smaller than the AIFF?
Usually yes: a minute of audio takes about 10.6 MB as AIFF and about 1.4 MB as MP3 at 192 kbps. Lower the bitrate to shrink it further; 128 kbps is plenty for speech.
