Quick summary
You can increase YouTube video volume using the keyboard arrow keys or the on-screen volume slider — and if the video is still too quiet, raising your device's system output volume gives an extra boost.
Steps
- Go to youtube.com and open any video you want to watch.
- Click anywhere on the video player to make sure it is focused.
- Press the Up arrow key on your keyboard to increase volume in 5% increments; press the Down arrow key to decrease it.
- Alternatively, click the Volume icon and drag the slider right to increase or left to decrease the volume.
- If the video is still too quiet, right-click the volume icon in your system tray and raise your device's output volume.
