Converting MP4 to MP3: what to know
MP4 is converted to MP3 to keep only the sound of a video: the music from a clip, a lecture recording, a podcast or a voice message. The video track is dropped, and the file becomes many times smaller.
You don't have to keep the whole video: set the start and end on the timeline to save just the part you need. The bitrate is chosen automatically by default; for music pick 192–320 kbps, for speech 96–128 kbps is enough.
The video is processed right in your browser, so large files up to 2 GB don't need to be uploaded anywhere; the speed depends only on your device.
MP4 or MP3: which to choose?
MP4 (MPEG-4 Part 14)
MP4 is the most compatible video format: it plays on phones, TVs, browsers and social networks.
Best for publishing and sending videos - maximum compatibility at a reasonable size.
MP3 (MPEG-1 Audio Layer III)
MP3 is the most universal audio format: compact files that play anywhere.
Best for music, podcasts and audiobooks on any device.
What happens when converting MP4 to MP3
Only the soundtrack is saved, the video track is dropped. You can trim the fragment and change the bitrate, channels and sample rate.
MP4 files up to 2 GB are supported; the actual limit also depends on the free memory of your device.

Frequently asked questions
How do I convert MP4 to MP3?
Add MP4 files above - MP3 is already selected as the target format. Adjust the settings if needed, start the conversion and download the MP3 files.
Can I change the MP3 quality?
Yes. Set the quality from 1 to 100 in the file settings: the lower the value, the smaller the file.
Can I cut out just part of a song from a video?
Yes. Mark the start and end of the fragment on the timeline, and only that part goes into the MP3.
