Online video converters can be useful when you only need to save one short audio file and do not want to install software. However, online tools change often. Some pages may show misleading download buttons, pop-up ads, bundled extensions, or scripts. For safety, avoid sites that ask you to install extra software, disable browser protection, or grant unnecessary permissions. Here's some sample sites for your reference.
1. ytmp3.cc (now convertytmp3.org)
YTMP3 is a clean and uncluttered website on which you will not be bothered by any ads. And the operation interface is self-explanatory. Enter a YouTube video URL, choose MP3 or MP4 according to your needs, click “Converter”, and download the converted file. YTMP3 stands out for its simple and clean steps, yet there still are some shortcomings. It doesn’t support converting a video longer than one hour in consideration of conversion speed.
