# Change video speed for free

> Speed up or slow down a video from 0.25× to 4× with Tella's free browser-based video speed changer.

You can use Tella's free video speed changer without an account. It runs in your browser, so your video is not uploaded to Tella.

  Change a video's speed without a watermark or sign-up.

## Change your video's speed

1. Open the [free video speed changer](https://www.tella.com/tools/video-speed-changer).
2. Drop an MP4, MOV, or WebM file into the tool, or click **Choose a video**.
3. Choose a speed from 0.25× to 4×.
4. Preview the video at the selected speed.
5. Turn on **Remove audio** if you want a silent export.
6. Click **Export**, then download the finished video.

If you change the speed or audio setting after exporting, you can export the same file again without selecting it another time.

## What to expect

* The exported video has no watermark.
* Speech keeps its natural pitch when you change the speed.
* There is no fixed file-size or duration limit, but long or high-resolution videos take more time and memory to process.
* Your browser exports an MP4 when it supports the required codecs. Otherwise, it exports a WebM file.

<Note>
  The selected speed applies to the entire video. To change the speed of only one section, edit that section separately before using the tool.
</Note>

<Warning>
  Some browsers cannot decode HEVC videos, including some iPhone recordings. If your file does not open, try the latest version of Chrome or convert it to H.264 first.
</Warning>
