Frequently asked questions

Is my audio uploaded?

No. Conversion runs in your browser with a WebAssembly build of FFmpeg, so your recordings never leave your device.

Can I convert other audio formats too?

Yes. Any of our audio converters accepts M4A, WAV, OGG, AAC, FLAC and more, not only the format in the title.

Will it sound worse?

Converting between compressed formats loses a tiny amount of quality. At 192 kbps or higher it’s inaudible for almost all listeners.
