You can download YouTube videos to MP4 files at 144p, 240p, 360p, 480p, 720p, 1080p and even 4K if the resolution is available. You can also save a video as a low quality FLV file at 240p, or MP3 file that you can add to your iTunes playlist.

What is more, Airy seamlessly integrates with your web browser and helps you send the video link directly to Airy with just a click of a mouse button. Apple’s Safari, Mozilla Firefox, Google Chrome and Opera are between the browsers supported by the app.
To integrate Airy into one of the above mentioned browser and other browsers that support this feature, you need to drag the link from Airy’s web browser integration page into your browser’s bookmarks bar. Every time you find a video you like and want to download, you can click on the bookmark to send the link to Airy for download.
