Speed Up or Slow Down Video Online — Free Tool

Change video playback speed instantly with this free online tool. Speed up videos to create time-lapse effects, or slow them down for dramatic slow-motion sequences — no software installation required.

How to Use the Speed Multiplier

Upload your video file and set a speed multiplier. A value less than 1 slows the video down; greater than 1 speeds it up. For example:

  • 0.25× — Quarter speed (4× slower). Great for analyzing fast action or creating dramatic slow-motion.
  • 0.5× — Half speed (2× slower). Smooth slow-motion effect, ideal for sports highlights.
  • 0.75× — Slightly slower. Subtle slow-down for emphasis without looking unnatural.
  • 1× — Original speed (no change).
  • 1.5× — 50% faster. Good for speeding up tutorials or lectures.
  • 2× — Double speed. Common for time-lapse and fast-forwarding through footage.
  • 4× — Quadruple speed. Creates quick time-lapse effects from longer recordings.
  • 8× to 16× — Extreme speed-up for condensing hours of footage into seconds.

You can also set a target video length in seconds, and the multiplier will be calculated automatically. This is useful when you need a specific duration for social media posts or presentations.

You can specify the start and end times to change speed only for a selected part of the video. Leave both fields empty to change speed for the entire video.

For sound, you can choose to keep the audio track at the original pace, change the speed together with video, or mute the audio altogether.

Frequently Asked Questions

How do I speed up a video online?

Upload your video, set the speed multiplier to a value greater than 1 (e.g., 2 for double speed), and click "Change video speed!". Your sped-up video will be ready to download in seconds.

How do I make a slow-motion video?

Set the speed multiplier to a value less than 1. For half-speed slow motion, use 0.5. For quarter-speed dramatic slow-mo, use 0.25. Note that slowing down a video too much may result in choppy playback if the original frame rate is low.

Can I speed up only part of a video?

Yes. Enter the start and end times (in seconds) to apply the speed change only to that segment. The rest of the video will play at its original speed.

What happens to the audio when I change video speed?

You have three options: mute the audio entirely, keep the original audio unchanged (it will go out of sync with the video), or change the audio speed together with the video (pitch will change).

Is this tool free?

Yes, 100% free with no watermarks, no signup, and no conversion limits. Files are automatically deleted one hour after upload for privacy.
