Converting MP4 to MP3

MP4 is typically used for sharing and uploading video, because it plays almost everywhere, while MP3 is used for music, podcasts and any sound you want to play on any device.

What changes when I convert MP4 to MP3?

The converter keeps only the sound from the MP4 file and drops the picture. The new MP3 file holds just the audio.

MP3 is a lossy format, so the sound is re-encoded with a small loss of detail. Most people cannot hear the difference.

What are the limits when converting MP4 to MP3?

You can convert up to 10 videos a day for free, each up to 1 GB and 10 minutes long, at up to 1080p. Pro removes the daily limit and accepts videos up to 2 GB and 60 minutes long, with no resolution cap. See the plans.
