Speed up or slow down your videos online — for free, right in your browser. Use Speed Mode
for precise
control from 0.5x to 4x, or switch to Duration Mode to set an exact target length. No
signup, no
watermark, no software to install.
How to Change Video Speed
Speed Mode — Choose a Multiplier
- Upload your video — Click "Select Video" or drag and drop. We support MP4, MOV, AVI,
and other common formats.
- Set the speed — Use the + and − buttons to adjust from 0.5x (slow motion) to 4x (fast
forward) in fine 0.05x steps. A few common settings:
- 0.5x — Half speed. Creates a slow-motion effect.
- 1.5x — Slightly faster. Good for speeding up presentations without making them
feel rushed.
- 2x — Double speed. Good baseline for time-lapses and shortening long videos.
- 4x — Quadruple speed. Best for dramatic time-lapses.
- Mute audio (optional) — Check "Mute video" if you don't want audio in the output.
Useful when audio sounds unnatural at high speeds.
- Click "Change Video Speed" — Wait for processing, then download your file.
Duration Mode — Set an Exact Length
Instead of picking a speed multiplier, you can tell the tool exactly how long you want the final video to
be:
- Upload your video and switch to Duration Mode
-
Pick a target duration:
- 0:15 — 15 seconds (great for TikTok, Reels, YouTube Shorts)
- 0:30 — 30 seconds
- 1:00 — 1 minute
- 3:00 — 3 minutes
- Custom — Enter any duration you need
- The tool automatically calculates the right speed multiplier to fit your video into the chosen
length.
- Click "Change Video Speed and download.
Tip: Duration Mode is particularly useful when you need to fit a longer video into a
specific time limit — like squeezing a 2-minute clip into a 30-second Reel. No math required.
When to Speed Up or Slow Down a Video
Create Time-Lapse Videos
Speed up long recordings to show hours of activity in seconds. Time-lapses work well for construction
progress, cooking processes, art creation, sunsets, or any slow event that becomes interesting when
compressed. Try 2x–4x depending on the original length.
Create Slow-Motion Effects
Slow your video to 0.5x to highlight fast action — sports moments, product demos, dance moves, or anything
that happens too quickly to appreciate at normal speed. The output keeps smooth playback at the lower
speed.
Fit Videos to Social Media Time Limits
Need a 45-second video to fit into a 15-second TikTok? Use Duration Mode to set exactly 15 seconds, and the
tool will speed it up by 3x automatically. This works for Instagram Reels, YouTube Shorts, or any platform
with strict time constraints.
Speed Up Tutorials and Presentations
Long screen recordings, lectures, and presentations are often too slow. A 1.25x–1.5x speed increase keeps the
content understandable while saving your viewers' time. This is the same idea as podcast speed controls, but
for video — and with proper re-encoding so the output file plays at the new speed natively.
Speed Up for GIF Creation
Want to turn a video into a fast, punchy GIF? Speed up the footage first, then use our Video to GIF tool to convert it.
Speed Mode vs Duration Mode
Both modes produce the same quality output. The difference is just how you tell the tool what you want.
What Happens to Audio?
By default, audio speed changes together with the video. This means:
- Speed up → Audio gets faster and higher-pitched
- Slow down → Audio gets slower and lower-pitched
If the audio sounds unnatural at your chosen speed (common above 2x or below 0.75x), use the "Mute
video"
checkbox to remove it. You can always add new audio later using a separate tool.
For most time-lapse and fast-forward use cases, muting is the better choice. For small speed adjustments
(1.25x–1.5x), the audio usually still sounds fine.
What Makes This Tool Different?
- Two modes — Speed Mode (pick a multiplier) and Duration Mode (pick a target length). Most free tools only offer one.
- Fine 0.05x increments — Not just 0.5x, 1x, 2x. You can set 1.25x, 1.75x, or any value in between.
- Duration presets — One-click options for 15s, 30s, 1min, 3min — designed for social media time limits.
- Mute option — Remove audio with one checkbox.
- Free, no watermark — No branding on your output.
- No signup — Upload and process immediately.
- No software — Works in any browser.
- Privacy-first — Videos encrypted, never shared, deleted after 24 hours.
Related Tools
- Video Trimmer — Cut your video to the right section before changing speed. Trim first, then speed up — better results than speeding up a long video with unwanted parts.
- Video Compressor — Reduce file size after processing. Speeding up a video often increases bitrate; compress it afterward for easier sharing.
- Video to GIF — Speed up footage and convert it to an animated GIF.
- Resize for Instagram — After speeding up for a Reel, resize to 9:16.
- Video Converter — Convert to MP4 or another format after speed changes.
- Video to MP3 — Extract audio before or after speed changes.
