FAQ
About this tool
Why extract MP3 from MP4
Sometimes you only need the sound: webinar, interview, podcast or background music. MP3 is easier to send via email, upload to social media and edit. OKDOCS tool quickly extracts the audio track right in the browser.
Step-by-step workflow
- Upload an MP4 video.
- Click "Extract audio" and wait for completion.
- Download the ready MP3 and use it in editing or distribution.
When this is useful
- Publishing audio version of a webinar or lesson.
- Creating a podcast from a video recording.
- Preparing tracks for subtitles or translation.
- Extracting background music or commentary for editing.
Tips
For minimum size, process the MP3 in an editor after downloading or wait for the "Compress MP3" tool to appear. If the sound is too quiet/loud, normalize it in a DAW. Keep the original MP4 — this way you can extract audio again or get another fragment.
