How to convert AIFF to MP3
Logic, GarageBand, and sample libraries save AIFF files, which are as big as WAVs. Open one here, or a folder of them, and save each as an MP3 that's a fraction of the size. The AIFF to MP3 converter runs in your browser, so nothing is uploaded.

What to expect
- Supported inputs
- AIFF and AIFF-C files (.aif, .aiff, .aifc), 8 to 32-bit and float, and any other audio or video file.
- What happens
- The uncompressed sound is encoded as MP3. MP3 is selected first; you can choose WAV, FLAC, or another format.
- Limits
- MP3 holds two channels, so surround files are mixed down to stereo. Very long recordings depend on your device's memory.
