# Speed up video 2×

> Double the speed of any video permanently — watch hour-long recordings in thirty minutes, on any player.

Speed up or slow down any video or audio from 0.25× to 4×, keeping audio pitch natural so voices do not sound chipmunked or slurred. Runs locally in the browser; no upload.

## 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

### Will voices sound like chipmunks?

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.

### Why make a permanent 2x copy instead of using player speed?

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.

### How long does 2x conversion take?

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.

### Is it really free?

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.

### Do you upload my files?

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.
