The basic method that works on most sites
The simplest way to download a video from most websites is to use a browser extension or a dedicated download tool. These tools work by detecting the video file on the page and giving you a button to save it to your computer. The video downloads as an MP4 file (or sometimes WebM or other formats) that you can watch offline in any media player.
Before you download anything, check the website's terms of service. Some sites allow downloads for personal use, while others forbid it entirely. Copyright holders own the video, not the website hosting it — downloading doesn't change that. If you're downloading your own content, a friend's video, or something explicitly marked as free to download, you're on solid ground. If you're downloading a movie, TV show, or music video from a streaming service, you're violating their terms and potentially breaking copyright law.
The method you use depends on what device you're on and what website the video is hosted on. Different sites use different video players, so a tool that works on one site might not work on another.
Key Takeaways
- Browser extensions like Video DownloadHelper and 4K Video Downloader detect videos on web pages and let you save them as MP4 files to your computer.
- Streaming services like Netflix, YouTube, and Disney+ have their own built-in download features that are legal to use within their terms of service.
- Websites that host user-uploaded videos like Vimeo and TikTok often block downloads, but some allow it if you own the account or have permission from the creator.
- Always check the website's terms of service and respect copyright before downloading — downloading doesn't change who owns the video.
- If a download tool stops working, the website likely changed how it serves videos, and you'll need a different tool or method.
Using a browser extension to download videos
Browser extensions are the fastest way to download from most websites. The most reliable option is Video DownloadHelper, which works in Firefox and Chrome. Install it from your browser's extension store, then visit any webpage with a video. A small icon appears in your toolbar — click it, and the extension shows you every video on the page. Select the one you want and choose your format (usually MP4 is the best choice for compatibility). The video downloads to your Downloads folder.
Another popular choice is 4K Video Downloader, which you install as a standalone program rather than a browser extension. Open the program, paste the video's web address into the box at the top, and click Download. It works on Windows, Mac, and Linux. The free version has limits on how many videos you can download per day, but it's enough for occasional use.
These tools work on most websites, but not all. YouTube, Vimeo, TikTok, and streaming services often block them because they don't want videos downloaded. If you click the extension button and nothing happens, the website is blocking the download tool.
Downloading from YouTube and similar platforms
YouTube has a built-in download feature, but only for videos you uploaded yourself or videos in YouTube's offline library (available with YouTube Premium). To use it, open the video, tap the three dots below the title, and select "Save video." The video appears in your Offline section and stays there for 30 days.
If you want to download someone else's YouTube video, you need a third-party tool. yt-dlp is a free command-line program that downloads from YouTube and hundreds of other sites. It requires typing commands in a terminal, which is more technical than using an extension, but it's more reliable because YouTube actively works to block extensions. You can find instructions on GitHub.
For TikTok, the app itself has a download button — open the video, tap the share icon, and select "Save video." This saves it to your phone's camera roll. On desktop, TikTok blocks downloads, so you'd need a third-party tool, though TikTok actively blocks those as well.
Downloading from streaming services
Netflix, Disney+, Amazon Prime Video, and HBO Max all have built-in download features. Open the show or movie, look for a download icon (usually a downward arrow), and tap it. The video downloads to your device and stays there until you delete it or your subscription ends. These downloads only work on the app — you can't watch them in a web browser.
The download feature is legal because you're using the service the way the company designed it. You're not breaking any rules or circumventing any protections. The tradeoff is that you can only watch the download on devices where you're signed into that account, and the video disappears if your subscription lapses.
Some streaming services limit how many downloads you can have at once or how long you can keep them. Check your account settings to see the limits for your service.
When download tools stop working
If a browser extension or download tool suddenly stops working on a site where it used to work, the website changed how it delivers video. Websites update their video players and security regularly, which breaks older download tools. This is especially common on YouTube, which updates its defenses multiple times per year.
When this happens, you have a few options. First, check if the extension has a newer version — update it and try again. Second, try a different tool. If Video DownloadHelper doesn't work, try 4K Video Downloader or yt-dlp. Third, check the tool's website or GitHub page to see if other users are reporting the same problem. If many people are affected, the tool's developer is probably already working on a fix.
If nothing works, the website may have made downloading impossible on purpose. Streaming services and major platforms actively prevent downloads because they want you to watch through their app or website, where they can show you ads and track your viewing.
Downloading videos on your phone
Phone browsers don't support extensions the way desktop browsers do, so the process is different. On iPhone, most download tools don't work because Apple restricts what apps can do. Your best option is to use an app like Documents or Puffin Browser, which have built-in download features. Open the video in the app, tap the download button, and the video saves to the app's storage.
On Android, you have more options. Apps like VidMate and Snaptube let you paste a video link and download it. You can also use Firefox on Android with the Video DownloadHelper extension, which works the same way as on desktop.
Phone storage fills up quickly with videos, so download only what you actually need. A one-hour video takes up about 500 MB to 2 GB depending on quality.
Understanding video formats and quality
When you download a video, you usually choose a format and quality. MP4 is the most common format and works on almost every device and media player. WebM and MKV are other formats you might see, but they don't work on all devices. If you're not sure, choose MP4.
Quality is measured in resolution: 1080p (full HD) is sharp and clear, 720p is good for most purposes, and 480p is smaller but grainier. Higher quality means larger file size. A 10-minute video at 1080p might be 100 MB, while the same video at 480p might be 20 MB. Choose based on how you plan to watch it — if you're watching on a phone, 720p is usually enough.
Some download tools let you choose between video-only and video-plus-audio. Video-only files are much smaller but won't have sound. Always choose the option that includes audio unless you specifically want just the video.
Frequently Asked Questions
Is it legal to download videos from YouTube?
It depends on the video. Downloading your own videos or videos marked as free to use is legal. Downloading copyrighted movies, TV shows, or music videos is not legal, even though the tools exist to do it. YouTube's terms of service forbid downloading except through their official features.
Why do some websites block downloads?
Websites block downloads to control how their content is used. Streaming services want you to watch through their app so they can show ads and track what you watch. Content creators and copyright holders want to prevent unauthorized copying. Blocking downloads is one way they enforce this.
Can I download a video if the creator doesn't want me to?
You can use a download tool to do it, but that doesn't make it legal or ethical. The creator owns the video, and downloading it against their wishes violates copyright law. The only exception is if the video is in the public domain or explicitly licensed for reuse.
What's the difference between downloading and screen recording?
Downloading saves the actual video file from the website. Screen recording captures whatever is on your screen while the video plays. Screen recording is usually lower quality and takes longer, but it works on sites that block downloads. Both methods are subject to the same copyright rules.
Will downloading a video get me in trouble?
Downloading for personal use from sites that allow it is safe. Downloading copyrighted content from streaming services or uploading downloaded videos to the internet can result in copyright strikes, account bans, or legal action from the copyright holder. The risk is higher if you share the video than if you keep it private.
