Common questions
Before you export the MP3.
Can I batch convert AIFF to MP3?
Yes. The tool accepts up to 100 AIFF files in one queue and converts them one by one locally, without sending the audio to 44Stems servers.
Are my AIFF files uploaded?
No. Conversion runs locally in your browser. Your AIFF files are decoded and encoded on your device, then downloaded as MP3 files or a ZIP.
Why convert AIFF to MP3 for music work?
AIFF is useful for production and mastering, but MP3 is easier to send, preview, pitch, and share. Producers often keep AIFF masters and export MP3 copies for review.
Can I split the converted track into stems?
Yes. After creating a smaller MP3 preview, open 44Stems to separate vocals, drums, bass, and instruments from the track.
