How to save just the audio from a video as MP3

1 min read · Works in Chrome

Quick answer

On the page, open the video in FileSnatch and choose Audio only from the arrow next to Download. For a file you already have, drop it on the panel and choose MP3.

The problem

Often you only want what a video says or plays: a song, a lecture, an interview. Video files are many times bigger than the sound alone, and online converters mean uploading and waiting.

How FileSnatch helps

Audio only saves just the sound of a video on a page, without downloading the picture.
Trim → Audio saves the sound of just one part.
The converter turns video files on your computer into MP3, M4A or WAV, privately.
Saving the sound of a single video is free.

Step by step

From a page
Open FileSnatch, click the video, then Audio only from the arrow next to Download.
Only a part
Click Trim, set From and To, choose Audio (MP3), then Save this part.
From your computer
Drop the video file on the panel, choose MP3, and Convert.

Good to know

M4A sounds the same as MP3 at a smaller size.
Music in a Telegram channel? Its songs save directly, with their covers.

Free and Pro

The sound of one video is free. Trims and conversions are 1 a day free, unlimited with Pro.
