Are you watching a YouTube video that's playing too slowly or too fast? It's easy to speed up (or slow down) the playback of any video on the YouTube website or the YouTube mobile app. Here's what to do.

How to change YouTube playback speed on the web
You can change the playback speed in both the web browser and the YouTube mobile app for iPhone, Android , and iPad. First, we'll show you how it works on the web.
To slow down or speed up a YouTube video in a browser, visit YouTube.com and navigate to a YouTube video. Find the playback toolbar and click the “gear” icon located in the lower-right corner of the video area.

In the menu that appears, click “Playback speed”.

In the “Playback speed” menu, you can select a speed anywhere between 0.25 times and 2 times the speed, including a custom value within that range. With “1” being the normal speed, any value less than 1 will slow down the video, while any value greater than 1 will speed up the video.

After that, click outside the menu to close and the next time you press the play button, the video will play at the speed you selected. If you need to change it back to normal, click the gear icon again, select “Playback speed” and select “1” from the list.
How to change YouTube playback speed on the YouTube mobile app
If you want to slow down or speed up a YouTube video on your iPhone, iPad, or Android device, first open the YouTube app. While a video is playing, tap the screen once to bring up the toolbar , then tap the three-dot button in the upper-right corner of the video frame.

In the menu that appears, select “Playback speed”.

In the “Playback speed” list that appears, select the speed you want. Remember that any value less than 1 slows down the video, while any number greater than 1 speeds up the video.

After that, close the menu and the video will resume at the selected speed. If you need to change back to normal speed, press the “ellipses” button again and change the speed to “1.”
