Change video speed online
Speed up or slow down a video in your browser — the audio keeps its natural pitch. No upload, no signup, free.
Speed up or slow down a video without uploading it. Choose a speed factor — 2x for a timelapse, 0.5x for a slow motion effect, or any value in between. The audio is pitch-corrected so it sounds natural at the new speed, not chipmunk-fast or slurred-slow. Useful for creating a timelapse from a long recording, slowing down a sports clip to study a motion, or fitting a video to a specific duration. Everything runs in your browser, so the file stays private. Free, no account, no watermark.
How it works
