I've tried so many YouTube converters over the years and most of them are either covered in sketchy ads, force you to install something, or quietly cap you at terrible quality. A friend put me onto youtubemp3hub last month and I've been using it ever since. You just paste the video link, pick your bitrate (128, 192, 256, or 320 kbps), and the MP3 lands in your downloads. No app, no account, no nonsense. I've used it on my laptop at home and on my phone waiting for the bus, and both work fine. The 320 kbps option actually sounds like the original track, which matters when I'm loading stuff onto my old MP3 player for the gym. If you still hoard music like I do, give youtubemp3hub.com a shot.
