Slow motion video
Make a dramatic 4× slow-motion clip.
How to use it
- Add your file. Drop it on the box above or tap it to pick it from your device.
- Let it work. Drop your video. The first time, the video engine loads once (about 31 MB, then cached by your browser).
- Download. Press Download. Nothing was uploaded, so nothing is stored anywhere.
What it does
Every frame is shown 4 times longer, so the clip becomes 4 times longer. The sound is sped up or slowed down to stay in sync without going deep and growly.
When to use it
Sports moves, dance, pets, splashes and anything that happens too fast to see properly.
Private by design
Most online tools upload your file to their servers. This one doesn't: it loads into your browser and does the work on your own phone or computer, so your files never leave it.
Questions
Is this slow motion video free?
Yes, completely free, with no account, no watermark and no daily limit.
Are my files uploaded?
No. Everything happens inside your browser on your own device. Nothing is sent to us or anyone else.
Does it work on iPhone and Android?
Yes, in a modern browser. Phones are slower than computers for video, and very long or 4K clips can run out of memory on older phones.
