The simplest way: YouTube's built-in download feature
YouTube Premium subscribers can download videos directly through the YouTube app or website. Open the video you want, tap or click the download icon (it looks like a downward arrow), choose your quality, and the video saves to your device. This is the only method YouTube officially supports, and it's the safest because you're downloading from YouTube itself with no third-party software involved.
The catch: YouTube Premium costs money — currently around $14 per month, though the price varies by country. Downloaded videos expire after 30 days unless you renew your subscription, and you can only watch them in the YouTube app, not in a separate video player. If you cancel your subscription, your downloads disappear.
If you don't have YouTube Premium and want to download videos anyway, you'll need to use a third-party tool. The rest of this guide covers how those work, what the legal and security risks actually are, and how to use them safely.
Key Takeaways
- YouTube Premium's download feature is the official method and requires no extra software, but videos expire after 30 days and only play in the YouTube app.
- Third-party download tools work by converting the video stream into a file format your computer can play, but they violate YouTube's terms of service.
- The legal risk depends on what you're downloading: personal videos and creative commons content are safer than copyrighted music or movies.
- Free download websites often contain ads, malware, or tracking software — desktop applications are generally safer than browser-based tools.
- Downloaded videos take up significant storage space, especially at high quality, so check your available disk space before downloading.
How third-party download tools actually work
When you use a tool like 4K Video Downloader, yt-dlp, or an online converter, you're asking it to grab the video stream from YouTube's servers and save it as a file on your computer. The tool reads the video URL, finds the actual video data, and converts it into a format like MP4 or MKV that your computer's video player can open.
This process violates YouTube's terms of service. YouTube explicitly forbids downloading videos except through their official download feature. If you use a third-party tool, you're breaking that agreement — though YouTube rarely pursues individual users for this. They're more likely to block the tool itself by changing how their servers work, which is why download tools stop working periodically and need updates.
The legal picture is more complicated than the terms of service. In the United States, downloading a video you created yourself, or one released under a Creative Commons license, is legal. Downloading a copyrighted movie or music video without permission is not — that's copyright infringement. The gray area is everything in between: fan videos, covers, clips from TV shows. Whether downloading those is legal depends on fair use, which courts decide case by case and which is genuinely uncertain.
Desktop applications versus online converters
A desktop application like 4K Video Downloader or MediaHuman YouTube Downloader runs on your computer. You paste the video URL into the app, choose your settings, and it downloads the file. These tools are generally safer because they don't require you to visit a website, and the code is often open-source, meaning security researchers can read it and spot problems.
Online converters work in your browser: you go to a website, paste the URL, and download the file from there. The advantage is you don't install anything. The disadvantage is that many converter websites are funded by ads or data collection, and some contain malware. If you use an online converter, use one with a good reputation — y2mate, savefrom.net, and clipconverter are widely used, but even these have ads and tracking. Never download software that the converter website offers you, and be cautious about clicking ads.
For most people, a desktop application is the safer choice. 4K Video Downloader is popular and straightforward; yt-dlp is free and open-source but requires using the command line, which is more technical. Both are legitimate tools with active communities and regular updates.
Choosing quality and file format
YouTube videos are available in different resolutions: 360p, 480p, 720p, 1080p, and sometimes 4K. Higher resolution means better picture quality but also larger file size. A 10-minute video at 1080p is roughly 150 to 300 megabytes, depending on how much motion and detail it contains. The same video at 4K can be 500 megabytes to over a gigabyte.
Most download tools let you choose both resolution and format. MP4 is the most compatible — it plays on Windows, Mac, phones, and most media players. MKV is higher quality but doesn't play on all devices. WebM is what YouTube uses internally but is less useful for storage. For most purposes, choose MP4 at 720p or 1080p unless you have a specific reason for higher quality or a different format.
Before you download, check how much free space your computer has. On Windows, right-click your C: drive and select Properties. On Mac, click the Apple menu, select About This Mac, then Storage. If you're planning to download many videos, you might need to delete old files or add external storage.
Step-by-step download using a desktop application
This example uses 4K Video Downloader, which is available for Windows and Mac. Go to the 4kdownload.com website and download the installer. Run it and follow the installation steps — it's a standard software install with no hidden add-ons.
Open YouTube and find the video you want. Copy the URL from the address bar. Open 4K Video Downloader, and you'll see a text box that says "Paste Link". Paste the URL there. The app will load the video and show you options: resolution, format, and where to save the file. Choose your settings and click Download. The video will download to your computer — this usually takes a few minutes depending on video length and your internet speed.
Once it's done, you can open the file with any video player: Windows Media Player, VLC, QuickTime, or any other player your computer has. The video is now yours to watch offline, on any device, without needing YouTube or an internet connection.
Security risks and how to avoid them
The main security risk with downloading videos is malware — software designed to harm your computer or steal your information. This risk is highest with online converter websites, especially lesser-known ones. Ads on these sites often disguise themselves as download buttons, and clicking them can install unwanted software.
To stay safe: use a desktop application from a known source rather than an online converter. If you do use a converter website, use one with a solid reputation and never click ads or download anything the site offers you besides the video file itself. Keep your antivirus software up to date — Windows Defender (built into Windows) and Malwarebytes are both free and effective. If you're unsure about a website, search its name plus "malware" or "scam" in Google before using it.
Another risk is that download tools sometimes bundle other software during installation — toolbars, search engines, or tracking software. To avoid this, download from the official website only, read the installation steps carefully, and uncheck any boxes that offer extra software. If you see an option to install something you didn't ask for, uncheck it.
When downloads stop working and what to do
YouTube regularly changes how it serves videos to prevent downloading. When this happens, download tools stop working until their developers update them. If your tool suddenly stops downloading videos, check whether an update is available. Most applications have an "About" or "Check for Updates" option in the menu.
If an update doesn't fix it, the tool itself may be outdated or abandoned. yt-dlp is updated frequently and is usually the most reliable option when other tools break. It requires using the command line, which is intimidating if you've never done it, but there are tutorials available for both Windows and Mac.
Sometimes YouTube blocks a download tool entirely, and the developers can't fix it. In that case, you may need to switch to a different tool. This is why having a backup option is useful — if 4K Video Downloader stops working, you know yt-dlp or an online converter is available as a fallback.
Storage and organization after downloading
Downloaded videos take up space, so think about where you'll keep them. Create a folder on your computer called "Downloaded Videos" or something similar, and keep all your downloads there. This makes them easier to find and easier to delete later if you need to free up space.
If you're downloading a lot of videos, consider using an external hard drive. A 1-terabyte external drive costs $50 to $100 and can hold hundreds of videos. This keeps your computer's main drive from getting full and makes it easier to back up your videos.
Remember that downloaded videos don't update. If the original video on YouTube is edited, deleted, or taken down, your downloaded copy stays the same. If you're downloading something important, keep a note of the original URL in case you need to verify the source later.
Frequently Asked Questions
Is downloading YouTube videos illegal?
It depends on what you're downloading. Videos you created yourself are legal to download. Creative Commons videos are legal to download. Copyrighted movies, TV shows, and music videos are not legal to download without permission. For everything else — covers, clips, fan videos — the legality is unclear and depends on fair use, which courts decide case by case.
Will YouTube ban my account if I download videos?
YouTube's terms of service forbid downloading videos except through YouTube Premium, but YouTube rarely bans individual users for downloading. They focus on blocking the download tools themselves. That said, downloading is technically a violation of their terms, so there's always a small risk.
Can I download videos on my phone?
YouTube Premium allows downloads on phones through the YouTube app. For third-party downloads on Android, tools like NewPipe work similarly to desktop applications. On iPhone, downloading is more difficult because Apple restricts what apps can do, and most download tools don't work well on iOS.
What's the difference between downloading and screen recording?
Downloading grabs the actual video file from YouTube's servers. Screen recording uses your computer's built-in tools to record what's on your screen while the video plays. Screen recording is slower, produces lower quality, and takes up more space, but it's sometimes an alternative if download tools aren't working.
How long does a download take?
Most videos download in a few minutes, depending on length and your internet speed. A 10-minute video at 1080p usually takes 2 to 5 minutes on a standard broadband connection. Longer videos or higher resolutions take longer. The download tool will show you a progress bar and an estimated time remaining.
