MP4 to MP3 Converter FAQ

How do I extract MP3 from MP4?

Choose an MP4, convert it in your browser, preview the audio, and download the MP3. The video track is not included.

What is the file limit?

Convert one MP4 at a time. The file can be up to 100 MB and 30 minutes long. For a larger file, trim or compress the video first.

How long does conversion take?

Processing time depends on the audio length and your device. Keep this tab open until the MP3 is ready.

Can I choose the MP3 bitrate?

No. This converter makes MP3 audio at 192 kbps.

Does it work on my phone?

The converter runs in browsers on desktop and mobile, but large files can be harder for phones to process. If it fails, try a shorter file or a desktop browser.

Which browser works best?

For the broadest compatibility, use the latest Chrome on a computer or Android device. Safari 26 or later also has the audio decoder this tool needs. On iPhone and iPad, Chrome uses the same browser engine as Safari, so updating your device matters more than switching browser apps. Some audio codecs may still be unsupported.

Which video formats can I extract audio from?

This page handles MP4 files. For MOV, use the MOV to MP3 converter; for other formats, use the audio converter.

What happens if conversion fails?

The MP4 needs an audio track in a codec your browser can decode. Some files, including protected videos, cannot be converted here. Try another MP4 with AAC audio.
