    FAQ

    Frequently Asked Questions

    How many files can I throw at this before it starts asking me to pay?

    For AAC to MP3, you can queue up to 20 files in one run; Converter App is free and unlimited, with no usage counter and no strict file-size cap. Huge uploads still take longer because the audio stream is being re-encoded, not just renamed.

    Will my title, artist, album, and cover art survive the conversion?

    Do not replace your library originals until you check the downloaded track. This page converts the audio stream; tags and cover art from an M4A/MP4 wrapper may not carry over exactly.

    If I export at 320 kbps, will the MP3 sound identical to my original?

    Hard truth: AAC to MP3 is lossy-to-lossy, so some extra compression artifacts are possible. Pick a higher kbps setting for music and avoid repeated conversions, but a bigger output cannot rebuild detail the source already discarded.

    Be blunt: what happens to my uploaded audio after the conversion?

    Each job runs in an isolated sandbox, and the uploaded file plus the converted result are deleted automatically right after the job finishes. We do not keep a media library of your tracks.
