YouTube downloaders

Here are the best YouTube video downloaders in 2021

The year is 2021, and the world is going full digital. Digital entertainment is skyrocketing, with services like YouTube, Netflix, Hulu, and Disney Plus turning into more than just a luxury. Only one of these services remains free, though, and it's YouTube, although there are YouTube Premium and Music subscriptions available. So what if you want to enjoy YouTube for free and still have access to YouTube videos online? Then this guide of the best YouTube video downloading tools in 2021 is for you.

The best free YouTube downloader in 2021 is 4K Video Downloader. This free program puts many paid-for tools to shame for having no ads, allowing you to save videos in the format of your choice, and not placing watermarks on your downloaded clips. It’ll even let you extract the audio from a video or download an entire playlist. It's my YouTube video downloader of choice since it allows 4K and 8K resolutions.

However, if you don't need that much power, there are lots of more streamlined free YouTube downloaders around, which will let you enter the URL of the video you want to grab and do the rest of the work for you.

Not really. Using third-party apps to download YouTube videos is against YouTube’s terms of service, which state “You are not allowed to…access, reproduce, download, distribute, transmit, broadcast, display, sell, license, alter, modify or otherwise use any part of the Service or any Content except: (a) as expressly authorized by the Service; or (b) with prior written permission from YouTube and, if applicable, the respective rights holders.”

Downloading YouTube videos also opens you up to potential copyright infringement unless you have permission from the copyright holder, it’s in the public domain, or you own the video yourself.

Consequently, you are treading into questionable territory by downloading YouTube videos unless you use Google's apps. Make sure to use YouTube video downloaders wisely and only for personal purposes to avoid unpleasant surprises. It's one of these cases where you break the law but most likely nobody will pursue you as long as you stick to personal use.

Key features in YouTube video downloading tools

  1. Quality of The Video – You should be able to manipulate the quality of the video. It may range between low, medium, or high. Ideally, you should be able to manually choose specific a specific resolution like 360p, 720p, 1080p, and more. 4K resolution support is vital in 2021.
  2. Subtitles – We all like videos that are in different languages. In such cases, the use of subtitles is essential while playing it on YouTube or YouTube Premium. Logically, you’ll prefer to download those particular videos along with the subtitles.
  3. Batch Downloading – You can download the files individually or in bulk based on playlists from YouTube channels. 
  4. Multiple File Format Compatibility – You may want to download and save videos in multiple formats within your file manager. Having various options to choose from, like MP3, MP4, FLAC, or AAC, provides flexibility and device compatibility.
  5. Speed – The tool should be able to download and convert videos fast. The download connection shouldn’t be severely affected by fluctuations in internet and wi-fi connectivity.

WinX YouTube Downloader

2. WinX YouTube Downloader

Clear, powerful, and well designed – a very close runner-up.


  • Vast format selection
  • Playlist downloads
  • Multiple-video download support
  • No bloatware.


  • No 3d and 360-degree video support
  • No Linux support.

Running a very close second, WinX YouTube Downloader can download videos from all the most popular sites, including Facebook, Vimeo, and DailyMotion. Unfortunately, it's only available for Windows and macOS.

WinX is effortless to use. Just paste in a URL, select an output format and quality setting, and it will be added to the current batch.

Once you've added all the videos you want to download, click the ‘Download' button, and they'll all be processed at once and saved to the destination folder of your preference.

WinX YouTube Downloader can download 4K video when available. WinX YouTube downloader's only disadvantages compared to 4K Video Downloader is the lack of 3D and 360-degree video support and the lack of Linux support. If this isn't a problem for you, this free YouTube downloader is a great choice.

3. Any Video Converter Free

Download and convert videos, bundled with a video editor.


  • Vast format support
  • Built-in video editor


  • No multiple-video downloads and bundled extra software
  • Lack of Linux support.

Any Video Converter Free is one of the best free YouTube downloaders for Windows and macOS. The only drawback is that this free version limits you to download a single video at a time, but if you're looking for a free solution, this is something you may decide you're happy to put up with.

There are many video formats to choose from, and there's even a basic video editor built into this YouTube downloader. This can be used to crop a video you download, add simple effects such as color adjustment, and add overlay text.

Free YouTube Video Downloader is easy to use, but it doesn't have the best user experience. Regardless, it's a very decent choice for free YouTube video downloads. Avoid the bundled ByteFence and Yahoo software during installation, and you're ready to start using it.

4. Free YouTube Download

The biggest what-if of YouTube video downloaders.


  • Multiple-video downloads
  • Auto-download option
  • Shutdown-pc-when-done option.


  • Three-minute time limit.

Free YouTube Download is a straightforward, tightly focused free YouTube downloader, totally on point with what it does. It's available on Windows and macOS.

Just paste in a URL from YouTube, and you can download the video in just a couple of clicks – or no clicks at all if you enable the Auto-Download option.

The formats available to you will depend on the original video's quality, but AVI, MP4, iPhone/iPod, and MKV should be available in most cases. It's also possible to convert to audio-only MP3 if you don’t need the footage as well. You can also download multiple videos at once.

There's only one real drawback, but it's a huge one – you can only use Free YouTube Download to grab clips that are less than three minutes long. That rules out most music videos for a start and is a real shame. The lack of Linux support is also a disadvantage, albeit a much less important one

Download, convert and merge videos as they're playing with aTube Catcher.


  • Multiple-video downloads
  • Supports most popular formats
  • Automatic file conversion


  • The installation process is full of adware, only available on Windows.

aTube Catcher can save videos from most big video hosting sites, thus the aTube in the name instead of YouTube.

Downloaded videos can be converted automatically to several popular formats, so you can tailor them for their intended use or whatever device you intend to watch them on. If you're looking to download a large number of videos, you can download them all at once, maxing out your bandwidth – something not available in all of the best free YouTube downloaders on this list.

This free YouTube downloader offers plenty of added extras, too, such as the ability to record any on-screen video, video merging, and disc burning. Unfortunately, it's only available for Windows.
