Why convert MIDI to AMR?

- Keep quality where supported.
- Private, no upload - runs in your browser.

When not to convert MIDI to AMR
- Skip AMR for archival masters: lossy compression discards detail, so keep the MIDI original.
- Keep a master copy: repeated exports stack small losses, so archive MIDI before batch AMR shares.
