Picture in Picture Helper is a free Chrome extension developed by Pol Muñoz. It falls under the category of Browsers and is classified as an Add-ons & Tools subcategory. This extension is designed to enhance your video viewing experience by providing useful shortcuts for entering and leaving Picture in Picture mode on any webpage that contains a video.

To activate Picture in Picture mode, simply click on the PiPHelper icon or use the keyboard shortcut Ctrl + Shift + P (Cmd + Shift + P on macOS). However, it is important to note that this extension relies on Chrome features that may not be enabled by default. In order to use the extension, you may need to enable certain experimental web platform features and Picture in Picture functionality through the Chrome flags settings.

For users on Chrome OS, an additional feature called "Surfaces for Videos" may need to be enabled. To do so, navigate to chrome://flags/#enable-surfaces-for-videos.

Overall, Picture in Picture Helper is a convenient tool for those who frequently watch videos and want to enjoy a Picture in Picture experience on Chrome. However, it is important to ensure that the necessary Chrome flags are enabled for the extension to work properly.
