Video to MP3: pull the audio out in the right format

Extracting the sound cannot make it better than the original. Your job is to pick the format and bitrate that are just enough for how you will listen or what you will do next.

Compress video: smaller files that still look good

A video's size is its bitrate multiplied by its length. Lower resolution saves the most, trimming saves the most reliably, and the quality level fine-tunes the rest.

Features

Change video speed turns long screen recordings or lectures into shorter watches, makes a sunset clip feel like a timelapse, or slows a goal down so you can see every move. Pick anything from 0.25× to 4×; the audio is stretched or squeezed to the same speed while voices keep their natural pitch.

  • Eight speeds from 0.25× to 4×.
  • Audio changes speed with the video while keeping its pitch.
  • Duration changes to match, e.g. 2× halves the length.
  • Accepts MP4, MOV, MKV, WebM and AVI; outputs MP4.
  • Results get a “-toc-do” suffix, e.g. “lecture-toc-do.mp4”.

Frequently asked questions

Will voices sound squeaky when sped up?

No. The audio changes speed but keeps its pitch, so people simply talk faster.

How long is a 10-minute video at 2×?

About 5 minutes. The new length is the original length divided by the speed you choose.

Can I change the speed of just one part?

The tool applies one speed to the whole video. Cut out that part first with Trim video, then change its speed.

Is 1.5× good for watching lectures?

Yes. 1.25× to 1.5× usually stays easy to follow while saving a lot of time.
