How to convert AIFF to MP3
Add one AIFF (or .aif) file, choose 128, 192, 256 or 320 kbps, then download the MP3. The default is 128 kbps. This online AIFF to MP3 tool runs the conversion on your device, so the file is not uploaded.
Why convert AIFF to MP3
AIFF is a common uncompressed format on Mac, including exports from Logic and other Apple audio software, so files can be large. Converting to MP3 makes a smaller file for sharing or for a player and editor that does not open AIFF.
Choose a bitrate for your MP3
MP3 uses lossy compression. A lower bitrate may make a smaller listening copy; a higher bitrate can retain more detail. Because AIFF is uncompressed, the MP3 you download will usually be much smaller than the source.
Need a transcript instead of an MP3?
You can send your original AIFF file to audio transcription without converting it here first. Transcription is separate from this free local converter: it uploads prepared audio and requires an account. Speaker labels are available when selected. Eligible personal accounts can receive 30 free minutes after card verification.
