DownVerter allows you to copy and paste a URL from YouTube and convert any video to one of dozens of formats on your desktop. It's fast, offers numerous options for conversions, including MP3 audio only, and it can process multiple videos at a time, providing a powerful tool for getting videos off the Internet on the fly.
After installation, which takes only a couple of minutes, you can start downloading videos right away. Choose a video from YouTube, paste the URL into the box, and it will load the data quickly. This allows you to verify you are downloading the right video before converting. You can then choose resolution, the type of file you want (and there are dozens of options to choose from), and then save the file to your hard drive in any location. Conversions load up in a queue and you can then click on the filename to open it from the app. The interface is great because everything runs from one screen; and while the graphics look a bit dated, it all runs very fast and without any crashes.
If you want to download videos from YouTube to your hard drive for local access, grab DownVerter. It's 100 percent free with no upgrade fee and it runs smoothly on the newest versions of OS X. With so many options, fast performance, and a clean interface for quick conversions, it's a tool anyone who frequently uses YouTube will appreciate.
