MP4 to MP3 Converter

Często zadawane pytania

Which MP3 bitrate should I use?

192 kb/s is transparent for most listeners and keeps files small; choose 320 kb/s for music archives and 128 kb/s for speech and podcasts.

Is there a faster option without quality loss?

Yes — use “Extract audio” with M4A. It copies the AAC soundtrack of an MP4 unchanged, which takes seconds and keeps the exact original quality.

Is my video uploaded to a server?

No. The file is read and written inside your browser tab using WebCodecs — nothing is uploaded, there is no account and no watermark. Once loaded, the page also works offline.
