Sometimes, all you want is to take the long route to a peaceful place and listen to your favorite YouTube podcast or a song cover that hasn’t been released on Spotify or SoundCloud yet. That’s exactly why video-to-MP3 converters became so popular—people discovered amazing content on YouTube but didn’t want to stream the entire video, especially while commuting, running, or just going about their day.
Luckily, there are ways to convert your favorite YouTube videos into high-quality 320kbps MP3s that offer an immersive listening experience. In this guide, I’ve included one of the best methods including a true goldmine you’ll end up using again and again for all kinds of content.
3 Best Tools to Convert YouTube Videos to 320kbps MP3
4K YouTube to MP3
4K YouTube to MP3 Downloader by 4KDownload is a fast and convenient tool that quickly converts YouTube videos into audio. Within seconds of pasting the link, you can download an audio version of the video.
The tool claims to offer 256 kbps audio quality, which is quite impressive—especially considering how clear and immersive the sound remains after conversion. Not only is the audio quality solid, but the process is also very straightforward. You can simply copy the YouTube link from the browser’s address bar or use the “Share” button to copy the link, then paste it into the tool to begin the conversion.
Any Free Converter
Right off the bat, when you land on Free AVC's YouTube Video to MP3 converter, you’ll notice that it features a lot of tools all in one place. At first glance, this might seem like overkill—especially if you’re just here to extract a song from a YouTube video. But don’t worry, it’s actually a good thing.
Free AVC is more than just a basic converter. It offers options to convert videos into popular formats like MP4, MKV, and MOV, extract audio from formats like MKV, MP4, MOV, and WEBM, and convert them into MP3. It can also transcode video to modern codecs like H264 (AVC), H265 (HEVC), AV1, and VP9 with high efficiency. On top of that, it compresses large files—like MKV videos—into smaller sizes without significant quality loss.
For someone who just wanted a simple MP3 file from a YouTube video, all these features might feel a bit overwhelming at first. But once you realize how powerful the converter is, you can feel confident that your file is in good hands.
The only real downside is that free AVC is only available as a downloadable software for Windows and iOS; you can’t use it directly in your browser.
Toolsmart Youtube to MP3
Toolsmart is an AI-powered collective hub available right from your favorite browser, packed with a variety of AI features. But that’s not our focus today, what we’re highlighting is one of its standout tools: the YouTube to MP3 converter.

What makes it even better is:
No signup required
No ads or pop-ups
No limits on usage
