The first time you install the software you’ll be presented with a Windows 8-style menu showing you all the options available. There’s a video to MP3 converter icon on the left, but this only works with files already on your PC. To download and convert a video to MP3 format in one step, select the YouTube downloader and paste its URL into the box labelled ‘URL del video’.

Next, take your pick from the dozens of possible output profiles. There are three MP3 quality options, so you can choose the right balance of file size and fidelity.

You can then indicate that you are interested in downloading the audio as an MP3 before you click the ‘Grab this clip!’ button to do just that. The MP3 you seek will be yours in next to no time.
