The 8 Best YouTube to MP3 Converters(Online and Apps) 2021

YouTube to MP3 converter will convert or cut the audio from the video with just a few clicks but the question is which is the best converter? And which provides more options to get the job done. We have tested and checked a number of online(Websites) and offline converters(Apps or software). In this article, I will show you the best converters in both categories.

Most of the websites and apps I mentioned below will allow you to download the youtube video in MP4 as well as MP3.

Before reading this article, please know that downloading a video or audio from youtube without the owner’s permission is prohibited. Reading YouTube’s terms of service will help you understand the copyright permissions better.

Online YouTube to MP3 Converters:

Online converters are websites that let you paste the URL of the youtube video and provides you with the option to convert it into MP3. I personally like online converters because, without any software, there is no setup or download required. Just paste the URL and the file is ready to download. However, if you’re a heavy user who constantly downloads the audio, then I would suggest you go for the converters in the form of applications(Offline Converters). These websites can be used on Android or iPhone as well.

1. Keepvid

Keepvid has been used by millions of peoples worldwide. It is one of the best free youtube downloader and converter with simple and basic options. It supports over a 100’s of websites including Youtube, Vimeo, Facebook, and SoundCloud.

The website also provides an app for easier downloads. But I would not recommend downloading the app since there are other apps that perform better as an application. Don’t get me wrong, the app is good but there are better alternatives.

Keepvid supports converting into MP3, M4A, and WEBM. Since the site mainly focuses on downloading video, it supports full HD resolutions up to 1080P, 2K, and 4K while downloading the video.

Additionally, it can process a large number of videos from a YouTube playlist providing an option to select the video you want to download. The file can be downloaded either by pasting the link or by searching within the Keepvid website. However, pasting the link is always the best option because the search is not up to the mark.

ClipConverter.CC is another popular youtube to MP3 converter. As the name suggests, it can convert the file in the form of clips. It supports more than 100 sites. The site also allows you to upload and convert the file as well. One thing that makes the ClipConverter unique is its ability to trim the video as per the user’s needs. Users can either covert the video from start to finish or from the required section by entering the required start and finish time.

It converts audio into MP3, M4A, and AAC and MP4, 3GP, AVI, MOV, MKV for the video respectively. Like Keepvid, the videos can be downloaded in 1080p, 2k, 4k and 8k. ClipConverter also provides an add-on for Safari, Chrome, and Firefox for easier downloads.

3. is a simple MP3 converter and downloader that lets you edit the ID3 tag before downloading. It supports video downloading up to 1080P. The site offers a tool to cut the audio for the required section.

Unlike ClipCoverter, provides a slider to change the start and end time of the MP3 audio. This feels handy while using the tool. Support up to 1080P is one of the drawbacks of the site since its competitors offer up to 8K. Annoying banners around the tool is also a disadvantage of the site.
