How it works
- 1
Upload your AUDIO
Drop it above, or click to pick from your device. We validate the format immediately — no spinning on a file we can't process.
- 2
Run the conversion
The recipe runs in an isolated cloud sandbox — same as every other ReFile job. No AI guessing involved; it's a hand-written command that does one thing.
- 3
Download the AUDIO
Result lands in seconds. Files auto-delete from our servers after 24 hours; signed download URLs expire in the same window.
Frequently asked
- Does it work on music?
- Yes — but music tolerates compression less than speech. Use at least 128 kbps if you care about quality.
