Common questions
Is my video uploaded anywhere?
No. The speed is changed inside your browser. Your video is never sent to a server.
Does the voice sound like a chipmunk when sped up?
No. The sound is stretched in a way that keeps the pitch, so voices sound natural, just faster or slower.
How do I make a timelapse?
Choose 4× (or run it twice for 16×) and pick No sound. Frames above 60 per second are dropped so the file stays small.
Is Change Video Speed free?
Yes, completely free, with no sign-up and no watermark. Keeping the sound works for videos up to 15 minutes.
