Cut watch time in half
Recorded lectures, webinars, standup recordings, and screen shares are usually half as dense as they are long — 2× is the sweet spot where speech stays fully intelligible but the meeting fits your coffee break. Because this tool writes a real 2× file rather than flipping a player setting, the speed survives sharing, embedding, and every app your viewers use.
Drop the file, keep the 2× preset, and hit the button. If 2× feels too brisk for a fast talker, the slider goes anywhere from 0.25× to 4× in 0.05 steps.
Frequently asked questions
No. The audio is time-stretched, not resampled — speech changes tempo but keeps its natural pitch, the same technique podcast apps use for their speed buttons.
Player speed settings vanish the moment you share the file or move to an app without them — messaging apps, presentation embeds, older players. A re-encoded 2x file plays fast everywhere, and it is also half the duration for platforms with length limits.
The video is re-encoded in your browser at roughly real-time speed, so a 10-minute video takes on the order of 5–10 minutes. Audio-only files are far faster. Everything runs locally — there is no upload or queue time.
Yes. The speed changer is completely free, with no signup, watermarks, or limits. We make money from our video translation service, not from this tool.
No. The speed change happens locally in your browser using WebAssembly. Your file never leaves your device — you can even disconnect from the internet once the page has loaded.
