Frequently asked questions

Which formats can I convert between?

MP3, WAV, M4A and OGG, in your browser via ffmpeg.wasm.

Why is conversion slow?

Encoding runs locally through ffmpeg compiled to WebAssembly, which is slower than native software; larger files take longer.

Are my audio files uploaded?

No — conversion happens entirely on your device.
