Airy is a useful app that allows you to download and keep all your best YouTube videos at your fingertips. It is a very good tool to download YouTube videos to Windows platform. You can save videos in different resolutions and file types. You can easily download Full HD and 4K Ultra HD videos to your hard drive and enjoy them anytime.

Key features include:

• You can save the video and watch it even if the original uploader removed it from YouTube.
• You can watch HD video regardless of your connection speed.
• You can transfer video for viewing on mobile devices.
• You can extract MP3 audio from video without saving the video.
• Enjoy the freedom of video sharing anytime, anywhere.

Airy downloads MP4, WebM, FLV and 3GP file types, and can also extract MP3 audio from YouTube videos; just paste the YouTube link into Airy, select MP3 from the list of file types and click “Upload”.

Airy’s browser integration allows you to simply click a bookmark to add a video URL to Airy for download.

Overall, the app is fairly basic, which makes it easy to use, but it lacks many of the features and options that are specific to YouTube downloaders, such as drag and drop and batch processing. The trial version has some limitations and will only allow you to download 2 free YouTube videos to test the app.
