Video Speed Changer

Make a video faster or slower, from quarter speed to 4x, with the sound kept in step. Free, no sign-up, and your file never leaves your device.

How to use it

  1. Choose a video.
  2. Pick a speed: under 1x slows it down, over 1x speeds it up.
  3. Press Change speed.
  4. Download the new video.

It runs on your device, so big files take longer on slower computers and phones. Nothing is uploaded or stored.

Got a long video? Let Renafy find the clips.

Upload a stream or podcast and get captioned clips ready to post, in the shape you pick. Plans from $13 a month, cancel anytime.
