One of the standout features of NoteBurner is its download speed. Thanks to its advanced core engine, it handled a 30-minute 4K video in just a few minutes during our test. The interface is also well-designed and supports up to 25 languages, making it super accessible if English isn’t your first language.

4K Video Downloader

4K Video Downloader is one of the most recognizable names in all YouTube 4K downloader apps. It lets you download high-quality videos in MP4 from YouTube, TikTok, Vimeo, Facebook, Bilibili, and several other popular platforms. In the free version, you can save single videos, playlists (up to 10 videos), and even full channels (up to 5 videos), but there are daily limits, 30 videos max per day. You’ll also run into ads, and batch downloads are unavailable unless you upgrade.

During testing, the download quality was good, but we did run into some lag and freezing with the free version. The app occasionally became unresponsive, which might frustrate anyone trying to save videos quickly. Still, if you're looking for a basic YouTube video downloader 4K and don’t mind a few limitations, it gets the job done.

Free to Use?

Yes, the free plan allows downloads, but there are daily limits and no batch downloads.

Pros:

• Supports multiple platforms.
• Clean interface, easy to use.
• Downloads in high quality up to 4K.

Cons:

• Limited download function and ad in the free version.
• App sometimes becomes unresponsive.

4 Best Free YouTube 4K Downloader Online Tool

1. DLBunny

If you're hunting for a free YouTube 4K downloader online, DLBunny is one interesting pick. It supports downloads in MP4, MP3, and JPEG from YouTube, TikTok, Douyin, Kuaishou, and a few others. The tool works straight from your browser, so you don’t need to install anything. Just paste a YouTube video link, and DLBunny will process it and let you download the video. It saves up to 30 minutes of download history, which can be helpful if you accidentally close the page.

There’s also some notes: while you can get 1080p or 1440p videos for free, 4K downloads are only available if you donate. Also, by default, the downloaded video has no sound. You’ll need to manually download the audio file and merge it with the video. It’s not the most convenient setup, but if you’re just looking for a lightweight YouTube downloader online tool with decent quality, it can work.

Free to Use?

Yes, it’s free to use, but 4K downloads require a small donation.

Pros:

• No installation needed.
• Supports MP4, MP3, and JPEG.
• Works with multiple sites including YouTube and TikTok.

Cons:

• 4K video requires payment.
• Downloads are silent by default.

2. Zeemo AI

Zeemo AI, as a caption and video editing tool, comes with a simple YouTube 4K downloader online, which works straight from your browser. Simply paste in the YouTube URL, pick the resolution you want (from 240p up to 4K), and download the video in MP4 or WebM format. It’s totally free and doesn’t ask you to install anything.

The downloader is pretty basic, though. Only the 360p version includes audio. If you want to download in higher quality like 1080p or 4K, you’ll need to download the audio separately and merge it with the video. On the bright side, Zeemo lets you add subtitles automatically before downloading, and you can even convert videos to text if you create an account. It’s a bit of a mix between a downloader and a lightweight video toolkit.

Free to Use?

Yes, the downloader is free to use.

Pros:

• Easy to use with a clean web interface.
• Supports MP4 and WebM downloads up to 4K.

Cons:

• Only 360p downloads come with audio.
• Sign-up needed for some features.

3. Y2DOWN

If you're after a quick, no-fuss way to download 4K YouTube videos online, Y2DOWN is a solid pick. It's completely free and runs smoothly on pretty much any device, whether you're on a laptop, tablet, or phone. The process is straightforward: paste in a link, choose your quality (up to 8K) and hit download. Videos under 4K come in MP4, while anything higher switches to WEBM. It's simple, clean, and gets the job done for most casual downloads.

What really makes Y2DOWN stand out is its support for audio. You can grab just the audio in 8 different formats, including MP3, M4A, and OGG, which is more than any other tool we tested. It even includes a dedicated YouTube Playlist Downloader, so you can pull down full sets of videos one by one. The only real catch is that it won’t handle videos longer than an hour.

Free to Use?

Yes, 100% free to use with no sign-up required.

Pros:

• Supports up to 8K video quality.
• Works on most devices.
• Offers 8 audio formats, including MP3 and M4A.

You can download videos in up to 8K resolution, grab audio tracks separately, and even save video thumbnails if you need. It’s not just for YouTube either. SnapAny offers individual downloaders for platforms like TikTok, Facebook, and Pinterest, plus a handy online tool for random videos or images from the web.

It claims to support MP4, WEBM, and 3GP formats, but during testing we could only find MP4 and WEBM available. The site is multilingual, offering four languages including English, Japanese, Chinese, and Spanish. However, it isn't compatible with older Apple devices like iOS 12 or earlier, which might be inconvenient if you're using an older iPhone or iPad.

Free to Use?

Yes, SnapAny is completely free.

Pros:

• Supports video downloads up to 8K.
• Offers multilingual audio downloads.
• Allows audio-only and thumbnail downloads.

Cons:

2 Best Free YouTube 4K Downloader Chrome Extension

1. Addoncrop

If you’re someone who watches a lot of YouTube on your browser and wants a smoother way to download videos, Addoncrop might be your go-to YouTube 4K downloader Chrome extension. It integrates directly into your browser, whether you're on Chrome, Edge, Opera, or a few others, and adds one-line download function bar right under the YouTube video. From there, you can instantly pick the resolution you want, starting at 144P and going all the way up to 8K.

For higher resolutions like 4K and 8K or if you want the video with sound, you’ll need to download a companion app. The app only works on Windows 7, 8, and 10, so Mac and Windows 11 users are left out. On the bright side, it also doubles as a YouTube Shorts downloader and supports MP3 audio and video thumbnails.

Free to Use?

Yes, it’s 100% free to use.

Pros:

• Supports downloads from 144P to 8K.
• Support download MP3 audio or thumbnails.
• Built-in YouTube Shorts downloader.

Cons:

• 4K/8K downloads with sound require a separate app.
• App doesn’t support Windows 11 or macOS.

2. YouTube Multi Downloader

If you're someone who likes to keep things simple yet powerful, YouTube Multi Downloader might be worth a look. It’s a free-to-use Chrome extension (with a little workaround) that lets you download YouTube videos in MP4 format from 360p all the way up to 4K. It also supports audio downloads in MP3 with six bitrate options, from 64 kbps to 320 kbps. Once installed, it adds a small download button right next to the YouTube channel’s subscribe button, so everything stays neatly in place without cluttering your screen.

However, this extension isn’t available directly from the Chrome Web Store, which means it isn’t as plug-and-play as some others. You’ll need to install Tampermonkey first before adding it. Also, the site does show a few ads, though most of them disappear if you’ve got a decent ad blocker running. As a free YouTube 4K downloader Chrome extension, it checks most of the boxes if you’re okay with a couple of setup hoops.

Free to Use?

Yes, you don’t need to pay any fee to use it.

Pros:

• Downloads videos up to 4K and audio up to 320 kbps.
• Simple UI with download button built into YouTube.

Cons:

• Shows ads unless blocked manually.
• Not available in Chrome Web Store directly.
