Frequently asked questions
Is quality lost?
MP3 is a compressed format: the conversion uses a high bitrate so the loss is inaudible in practice.
Is my file uploaded to a server?
No: the conversion happens entirely in your browser with ffmpeg in WebAssembly.
Is there a size limit?
Up to 250 MB per file works fine on normal machines.
