YouTube Speed Controller

About

YouTube Speed Controller is a Chrome extension that helps you speed up or slow down YouTube videos quickly, without opening YouTube’s playback sub-menus every time.

The controller appears directly on the video player, so you can adjust playback speed as you watch using your mouse or keyboard. You can drag it where you want, switch between +/- buttons and a slider, and customize the speed range to match your workflow.

Features:
- Change YouTube playback speed with one click or key press
- Use either +/- buttons or a horizontal slider
- Set your own speed increment
- Set your own minimum and maximum playback speed
- Works on embedded YouTube players outside youtube.com
- Saves time while watching tutorials, courses, talks, and long videos
- Premium adds customizable keyboard shortcuts and more advanced options
