MP3 is the format that plays on any phone, car player, and in the Music app. It is lossy: its files are small because part of the sound is left out when they are encoded. AIFF, the Audio Interchange File Format, is Apple's own audio format, developed for the Mac in 1988, and usually holds plain, uncompressed PCM audio, just like WAV.
Uncompressed audio needs no decoding, which is why sound engineers choose it for editing, applying effects, and mixing. To WAV Converter turns whole folders of MP3 files into AIFF in one drag and drop. Its automatic settings keep the sound as good as in the MP3, with no resampling or remixing, and all tags are transferred.

AIFF settings
AIFF is lossless and MP3 is not, so converting does not make an MP3 sound better. The automatic settings keep it from getting worse: AIFF Codec 'Automatic Selection', Sample Rate and Channels 'As Source', so nothing is resampled or remixed.
To convert to a particular AIFF Codec, Sample Rate, or Channels, set it up in Preferences / Format:
- Codec: PCM 8 to 32 Bit, PCM 32 Bit Floating Point, G.711, or ADPCM IMA QuickTime.
- Sample Rate: 8 to 192 kHz.
- Channels: Mono or Stereo.

Tags and artworks
To WAV Converter transfers all tags from MP3 files into the ID3v2.4 tags of AIFF files.
Enable 'Load missing tags and artworks from network' in Preferences / Tags to find song details and album covers in online databases, such as MusicBrainz, AcoustID, and CoverArt.
