How to Speed Up or Slow Down Video Online
Our free online tool changes the playback speed of your video right in the browser. Speed it up for a dynamic fast-forward effect, or slow it down for dramatic slow motion. No software needed — just upload, pick a speed, and download. Works with MP4, MOV, AVI, WebM, and MKV.
How It Works
- Upload your video file — drag and drop or click to select. Supports MP4, MOV, AVI, WebM, MKV up to 100 MB.
- Choose a speed: x0.5 or x0.75 to slow down, x1.5 or x2 to speed up. The new duration is shown on each option.
- Click Change Speed — the video and audio are re-timed together on the server.
- Download the result — a universally compatible MP4 file.
Speed Options
Slow Motion (x0.5, x0.75)
Stretch time for a cinematic slow-motion effect. Great for sports replays, dance, and dramatic moments.
Fast Forward (x1.5, x2)
Speed up long recordings, timelapses, or tutorials. Make a snappy, dynamic clip from slow footage.
Audio stays in sync
Both the video and its audio track are re-timed together, so sound stays perfectly aligned.
