MP3 to AIFF Converter

Convert MP3 files to AIFF. Free, without uploading.

This tool converts MP3 files to AIFF. MP3 is the most common audio format. It uses lossy compression and plays on almost every device.

AIFF is Apple’s uncompressed audio format, the Mac counterpart of WAV. AIFF is lossless, so the audio keeps the quality it has in the MP3 file.

Conversion runs on your device; your file is never sent to a server. The components download once on first use, and later conversions start right away.

How to use

1. Choose the MP3 file, drag it in, or paste its link.
2. Choose the audio quality; optionally enter a start and end time.
3. Press "Convert" and download the AIFF file.
