You need a YouTube video saved to your phone or computer, maybe to watch it offline during a trip, and you’re looking for the easiest way to do it. Before jumping on the first site promising “free download in one click”, it’s worth knowing that not all these tools are the same: some are perfectly safe, others hide aggressive ads or genuine risks to your device. In this guide I’ll show you both categories, so you can choose with your eyes open.
Before you start: what the law says
A necessary premise: downloading a video you don’t own the rights to, without the uploader’s authorization and outside the official features YouTube offers, almost always violates the platform’s Terms of Service and can amount to a copyright infringement, depending on the content and how you use it. This doesn’t apply to your own videos, public domain content, or material published under a license that explicitly allows downloading (many Creative Commons channels allow this, for example). Keep this in mind whichever method you choose below.
The simplest, official way: YouTube Premium
If your goal is just watching videos offline (you don’t necessarily need the file to keep outside the app), the simplest and risk-free solution is YouTube Premium: Google’s official subscription that, among other things, removes ads and lets you save videos for offline viewing directly in the app.
A cheaper tier called Premium Lite has also become available recently, built for people who mainly want to get rid of ads, and it now also includes offline downloads and background playback, without all the features of the full plan (like YouTube Music Premium). If your only interest is watching videos without a connection, it’s probably the option with the best balance of convenience and price. Full up-to-date details are in the official Premium Lite guide.
The limit of this method is that the file stays tied to the YouTube app: you don’t get an actual video file to move, edit, or open with other software.
If you need the actual file: open-source tools
When you need the file itself saved to your device, the most reliable tools are open source, with public code anyone can audit — a guarantee of transparency that the “free” sites covered further down don’t offer.
yt-dlp
yt-dlp is the go-to tool for anyone who doesn’t mind the command line: it’s free, open source, updated very frequently (new releases roughly every two weeks), and contains no ads, tracking, or unwanted bundled software. The trade-off is the initial learning curve: it runs from a terminal, not a traditional graphical interface, so it takes a bit of technical comfort or the patience to follow a step-by-step guide.
JDownloader
If you’d rather have a more traditional graphical interface, JDownloader is a free, open-source download manager available for Windows, macOS, and Linux. It supports hundreds of sites besides YouTube and lets you manage multiple queued downloads at once.
Browser extensions: Video DownloadHelper
If you’d rather not install a separate program, Video DownloadHelper is a Firefox extension (also available for Chrome and Edge) that’s been active and maintained for nearly twenty years, distributed exclusively through official browser stores — a good sign of trustworthiness compared to extensions from unknown sources. Once installed, it adds a download button whenever it detects a playable video on the page you’re viewing.
Watch out for “free YouTube converter” sites
Here’s the most important warning in this guide. Search “download YouTube video free” and you’ll find dozens of sites promising to turn a YouTube link into a downloadable file in seconds, with nothing to install: names like Y2Mate are among the best known, alongside many nearly identical services.
The problem is that several of these sites have been repeatedly reported for shady, potentially dangerous practices: invasive ads, fake download buttons that actually open an ad, pop-ups asking you to “allow notifications” that then bombard your device with fake virus alerts, and in some cases redirects pushing unwanted software installs. This isn’t an isolated risk tied to one site: it’s a pattern common to many services in this category, precisely because their revenue model relies on aggressive advertising more than the service itself.
The practical takeaway is simple: if a conversion site looks packed with multiple “Download” buttons, pop-ups, or insistent requests to enable notifications, leave immediately without clicking anything. The tools recommended above (YouTube Premium, yt-dlp, JDownloader, Video DownloadHelper) do the same job without these risks.
On mobile
On Android, avoid unofficial download apps that require installing an APK file downloaded outside the Play Store (a distribution pattern that, regardless of the specific app, always carries more risk than an app published on official stores). On iPhone and iPad, Apple’s built-in Shortcuts app can run scripts to download content, but the same caution applies: only download scripts from sources you know and trust.
On both systems, the simplest option remains the official YouTube app with a Premium or Premium Lite subscription, if your goal is offline viewing.
