YouTube Video Downloader: Best Free Online Tools, Apps & Safe Download Options
Compare YouTube video downloader options: official Premium downloads, free online tools, apps for iPhone and Mac, MP4 and 4K, plus safety tips.
A YouTube video downloader is any app, website, browser extension or command-line program that saves a YouTube video as a file on your device. People search for one to watch on a flight, keep a lecture for study, back up their own uploads, or pull a clip into an editor. The options range from YouTube's own offline feature to free online downloader sites, desktop software and open-source tools, and they differ a lot in safety, quality and legality.
Quick Answer (as of November 2026)
- The only route YouTube officially endorses for other people's videos is its own Download button, which needs YouTube Premium and keeps the video inside YouTube.
- Your own uploads can be downloaded as an MP4 directly from YouTube Studio, at zero cost.
- Authorized media inspection & direct downloads: You can inspect video formats and resolutions safely with our free YTSnap YouTube Video Tool.
- Third-party tools such as 4K Video Downloader+ and yt-dlp can save files, but using them on content you don't own or have permission for conflicts with YouTube's Terms of Service.
- Free online downloader sites carry the highest risk of fake buttons, aggressive ads and unwanted installers.
A Note on Legality: YouTube's Terms of Service bar downloading any content unless the service expressly allows it or you have prior written permission from YouTube and, where relevant, the rights holder. Copyright law may also apply, and it varies by country. This guide is not legal advice. It does not cover bypassing DRM, paywalls or access restrictions, and it points you to permitted options first: YouTube Premium, your own videos, Creative Commons content and videos you have explicit permission to save.
What Is a YouTube Video Downloader?
A YouTube video downloader reads a video's link, fetches the stream YouTube serves for it, and saves it as a file such as MP4 (video) or MP3 (audio). It comes in four forms:
- Online downloader sites that you use in a browser by pasting a link, with nothing to install.
- Desktop software for Windows, Mac or Linux, such as 4K Video Downloader+.
- Command-line tools such as the open-source yt-dlp.
- Mobile apps and browser extensions, which are the hardest category to trust because they often ask for broad permissions.
The Official Way: YouTube Premium Offline Downloads
If your goal is simply to watch offline, YouTube's own feature is the one option that is clearly permitted. According to YouTube Help, Premium members can download videos on mobile, and on a computer through Chrome, Edge, Firefox and Opera. Downloads are played back inside YouTube and can be watched offline for up to 29 days before the app needs to reconnect.
The trade-offs are real. Downloads are stored encrypted and can only be watched in the YouTube app, so you do not get an MP4 you can move or edit.

Frequently Asked Questions
What is the best YouTube video downloader?
For other people's videos, the best option is YouTube Premium's built-in Download feature, because it is the one method YouTube allows. For your own uploads, use YouTube Studio. If you have permission to save a video and want software, 4K Video Downloader+ is a well-known desktop choice, and yt-dlp suits technical users.
Is there a free YouTube video downloader?
Yes. YouTube Studio is free for your own videos. 4K Video Downloader+ has a free tier with daily limits, and yt-dlp is free open-source software. Free online downloader sites also exist, but they carry the most risk from ads, redirects and unwanted installers.
Can I download YouTube videos online without installing software?
Technically, yes, through online downloader sites or online web inspectors like YTSnap. We don't recommend shady third-party sites since many carry warning signs. If you use one, only for content you may save, and leave any page that offers an installer or shows several identical Download buttons.
Which YouTube video downloader works on iPhone?
The YouTube app with Premium is the reliable choice, and downloads stay inside the app. Third-party downloaders for iPhone often route you through extra installs or settings changes, which is a reason to avoid them.
Can I download YouTube videos on a Mac?
Yes. Premium downloads work in Chrome, Edge, Firefox and Opera on a computer. 4K Video Downloader+ lists macOS support, and yt-dlp provides a macOS executable. Get either from the official source.
Is a 4K YouTube video downloader available?
Some desktop tools advertise 4K, and 4K Video Downloader+ is reported to offer up to 8K where the video has it. Results vary, the video must exist in 4K, and some tools may save video without audio. Always check the result.
Can YouTube videos be downloaded in MP4 format?
For videos you uploaded, YouTube Studio gives you an MP4. Premium downloads are not MP4 files you can move around. Third-party tools can produce MP4s, but only use them for content you own or have permission to save.
Is a YouTube video downloader safe?
It depends on the tool and on how you get it. Official routes are safest. Online downloader sites and unfamiliar extensions are the most likely to expose you to fake buttons, malicious ads or bundled software. No tool is guaranteed safe, so check reputation and download only from official sources.
What is SaveTube?
SaveTube is a name used by online downloader sites, including save.tube, which advertises free downloads from YouTube and other platforms. A July 2026 MalwareTips scan rated save.tube suspicious and found no ownership details. We don't recommend it.
What is the safest way to watch YouTube videos offline?
Use YouTube Premium and download videos in the YouTube app or a supported browser. It keeps everything within YouTube's rules and avoids third-party software entirely.
Is it legal to download YouTube videos?
It depends. YouTube's terms prohibit downloads unless the service allows them or you have written permission, and copyright law may apply on top. Your own videos, Premium downloads, and content with a license or permission that allows it are the clear cases. This is general information, not legal advice.
Can I download just the audio or an MP3?
YouTube says it is not possible to download audio, music or MP3 files from the YouTube app, though Premium members can use YouTube Music for offline songs. Converters that extract audio raise the same permission and safety questions.
