About MP4 to MP3 conversion
The MP4 is opened locally and only its audio track is decoded, so even a large phone video is ready in seconds. Select the part you want, add fades if it is a clip from the middle, and export.
MP4 files with AAC audio open in all major browsers. MOV files from iPhones work in Safari and Chrome. Videos with Dolby Digital (AC-3) audio, common in TV recordings, can’t be decoded by browsers.
FAQ
Is there an MP4 size limit?
Files up to 500 MB. The video picture is never decoded, only the audio track.
Can I convert MOV to MP3?
Yes in Safari and Chrome, which decode the AAC audio in iPhone MOV files.
Are my files uploaded?
No. Audio is decoded, edited and encoded in your browser with the Web Audio API, WebCodecs and a JavaScript MP3 encoder. Nothing is sent to a server, so it also works on slow connections once the page has loaded.
Which formats can I open?
Anything your browser can decode: MP3, WAV, M4A/AAC, OGG Vorbis, Opus and FLAC, plus the audio track of MP4, MOV and WebM videos. Chrome and Edge support the widest range.
