Free, runs entirely in your browser — no sign-up, no file upload to a server.
What does the Audio Converter do?
It converts an audio file between formats such as MP3, WAV, and OGG.
How is the conversion done?
Using FFmpeg compiled to WebAssembly, running entirely in your browser tab — no server-side conversion is involved.
Where is my audio file processed?
Locally on your device; the file is never uploaded.
What should I do if a conversion is slow or fails?
Large or very long audio files can take a while since encoding runs in-browser — give it time, and if it still fails, try a shorter clip or a different source format.
