About MP4 to MP3 Converter

MP4 to MP3 Converter lifts just the audio track out of an .mp4 file and saves it as an MP3 you can listen to, share or drop into a playlist — no video editing software needed. Handy for saving a song from a recorded performance, pulling a podcast-style talk out of a screen recording, or just keeping the audio from a clip without the bulky video attached. Add your MP4, click extract, and download an .mp3 — everything happens right here in your browser, so your file is never sent to a server.

How to extract audio from an MP4

  2. 2

    Extract

    Click Extract audio and a progress bar shows you how it's going — everything happens on your device, so it can take a moment for a longer clip.

  3. 3

FAQ

Will the extracted audio sound as good as the original?
Very close — the audio is saved at a high-quality MP3 setting, so the difference is generally not noticeable for speech or music.
Does this work with other video formats too?
Yes — this page is set up for MP4 specifically, but the general Video to MP3 tool accepts MOV, WebM, AVI and MKV as well.
Are my videos uploaded anywhere?
No. Extraction happens entirely on your device, inside your browser — your files never get sent anywhere.
Is there a file size limit?
Each file can be up to 300MB, and up to 5 files per batch, to keep things reliable in the browser.
