MP4 to MP3 FAQ
Is this MP4 to MP3 converter free?
Yes. Convert as many videos as you like, up to 4 GB each, with no account.
Which MP3 quality should I pick?
192 kbps is a good default. 320 kbps is the most MP3 allows; it can’t add quality the video’s sound doesn’t have, so it only helps with high-quality sources.
What’s the difference between MP3 and M4A?
MP3 plays everywhere. M4A (AAC) is what most MP4 videos already contain, so it is saved without re-encoding: same quality, and faster.
Can I convert only part of the video?
Yes. Trim the video first, choose Keep editing this result, then save the audio.
Is my video uploaded?
No. The audio is extracted in your browser and the video never leaves your device.
