Speed footage up or slow it down — free, browser-based video speed changer.

Speed up video that runs long, or slow it down for smooth slow motion — one slider, instant preview, no software to install.
A 20-minute tutorial can drag in places — playing it back faster gets through it without cutting any content out.

A fast action shot can be hard to follow at normal speed — slowing it down makes the detail much clearer.

Change the pace, then trim, crop, or adjust volume — all before one export, without reopening the file.

Making footage play faster or slower solves very different problems depending on who's doing it, from saving time to catching detail.
Speed up video lectures to trim the total runtime without re-recording anything.
Slow down a play to review footwork or technique frame by frame instead of relying on memory.
Speed through a long recorded meeting so a team can catch up in a fraction of the time.
Fast-forward a slow grind sequence or slow down a clutch moment for a highlight reel.
Speed up video b-roll of a long process into a quick, watchable montage.

0.25x–4x
Slow footage down or speed it up, all in one continuous range.
Pitch-corrected audio
Speeding up doesn't turn voices into chipmunks or make speech sound strange.
Instant preview
See the new pace before you export anything at all.

“My course modules run long because I over-explain things on the first take. Speeding up the slower stretches gets episodes down to a length students finish.”
Malik F.
Online course creator
“I review match footage with my players every week, and slowing down a specific play frame by frame makes it obvious what needs to change.”
Coach Denise V.
Youth sports coach
“Our team records every planning meeting, and nobody has time to watch a full hour back. Playing it at 2x gets people caught up during a coffee break.”
Tomas B.
Project manager
“I speed up video footage of long builds and repairs into a 30-second montage for my channel. It's the single most-used tool in my whole workflow.”

What people usually ask before changing playback speed.
Load the recording, open the speed tab, and move the slider above 1x — a 20-minute recording at 2x plays back in 10 minutes, with nothing cut out.
Yes — move the slider below 1x. It works well for review purposes even on footage that wasn't shot specifically for slow motion.
No — the audio pitch is corrected automatically, so a sped-up voice still sounds natural.
Trim to the section you want first using the trim tab, then adjust its speed before exporting.
1.5x to 2x is usually the sweet spot for spoken content like lectures and meetings — fast enough to save real time, slow enough that speech still sounds natural.
Yes — changing speed and exporting a clip doesn't require an account or a subscription.
Yes — this speed changer works in mobile browsers on both phones and tablets, no app download required.
MP4, MOV, WebM, MKV, and most common formats a phone, camera, or screen recorder produces.
Move the slider, preview the result, and export — free, no account required, no software to install.
