About MP4 to MP3

Frequently asked questions
Are my files uploaded?
No. Everything happens in your browser on your own device. Your files are never sent to a server, so they stay private.
How long can the file be?
Up to about an hour of audio works on most computers. Very long files need a lot of memory because the whole track is decoded at once.
Which formats can I convert?
MP3, WAV, M4A/AAC, OGG/Opus, FLAC, and the sound from MP4, MOV and WebM videos.
