Common questions
How does Change Video Speed work?
Drop in a video, choose a speed from 0.25× to 4× with the slider or a preset, decide whether to keep or remove the audio, then run it. Frames and audio are retimed locally with WebCodecs — no upload involved.
Can I trust the output for production?
Your video is processed entirely in your browser's memory. It is never sent to a server, so it stays private on your device.
Will this tool stay free?
This tool is completely free to use, with no account, watermark or file-count limit.
