Whenever you're watching a YouTube video, just click on the toolbar icon. A small popup will appear, allowing you to click on the "Convert to MP3 / MP4" button, which will then take you to our site, FreeMP3Music.org. There, you can select the desired format and quality before starting the conversion process with a click on the 'convert' button. Once converted, simply press the 'download' button to save your file.
