The most common ways to download videos
You can download videos from most websites using one of three methods: a web browser extension, a standalone desktop program, or an online converter tool. Each has different strengths depending on what site you're downloading from, what device you use, and whether you want to keep the video in its original quality.
Browser extensions like Video DownloadHelper (Firefox) and Downie (Mac) sit in your toolbar and let you grab videos directly while you're watching them. Desktop programs like 4K Video Downloader and MediaHuman YouTube Downloader handle bulk downloads and give you more control over file format and quality. Online converters like y2mate and SaveFrom.net work in any browser without installing anything, but they're slower and sometimes show ads.
The method you choose depends mainly on which website you're downloading from. YouTube, Vimeo, and TikTok each have different technical barriers, and what works on one may not work on another.
Key Takeaways
- Browser extensions are fastest for downloading one or two videos, while desktop programs work better if you download regularly or in bulk.
- Online converter tools require no installation but are slower and may display advertisements during the process.
- YouTube, TikTok, Vimeo, and other platforms have different technical protections, so you may need to try multiple tools before one works.
- Downloaded videos take up significant storage space—a one-hour video in high quality can use 1 to 3 gigabytes of disk space.
- Check the website's terms of service before downloading, as some sites prohibit it or restrict what you can do with the video afterward.
Using a browser extension
Browser extensions are the quickest option if you download videos occasionally. They add a button to your toolbar that detects video on the page you're viewing. When you click it, you choose the quality and format, then the download starts immediately.
Video DownloadHelper works on Firefox and Chrome. When you visit a page with video, a small icon appears in your toolbar. Click it, select the quality you want (usually 720p, 1080p, or 4K if available), and choose MP4 or WebM format. The video saves to your Downloads folder. It handles YouTube, Vimeo, Facebook, Twitter, and hundreds of smaller sites.
Downie is Mac-only and works similarly. It detects videos on the page and lets you choose quality before downloading. Downie also converts videos to different formats after download if you need them in a specific format for another device.
The main drawback is that extensions sometimes stop working when websites update their code. If a tool suddenly fails on a site it used to work on, you may need to switch to a different method temporarily.
Using a desktop program
Desktop programs give you more control and work more reliably than extensions because they don't depend on your browser. They're worth installing if you download videos regularly, need to download in bulk, or want to convert videos to different formats automatically.
4K Video Downloader (Windows and Mac) is straightforward: paste the video URL, choose quality and format, and click Download. It handles YouTube, TikTok, Instagram, Vimeo, and others. You can paste multiple URLs at once and download them all in sequence. It also lets you download entire playlists or channels from YouTube.
MediaHuman YouTube Downloader (Windows and Mac) focuses on YouTube but does it well. It downloads videos, converts them to MP3 if you only want audio, and can grab entire playlists. The interface is simple: paste the link and choose quality.
yt-dlp is free and open-source but requires typing commands in a terminal window. It's more powerful than graphical programs—it handles more sites and gives you finer control over quality and format—but it has a steeper learning curve. If you're comfortable with a command line, it's the most reliable option.
Desktop programs typically cost between $15 and $30 for a one-time purchase, though many have free versions with limited features.
Using an online converter
Online converters require no installation and work on any device with a web browser. You paste a video URL into a website, choose quality and format, and the site converts and hosts the download for you.
SaveFrom.net and y2mate.com are the most widely used. Go to the site, paste your video URL in the text box, select the quality you want (usually 360p through 1080p), and click Download. The video downloads directly to your device. These sites work on YouTube, TikTok, Instagram, Facebook, and many others.
The trade-off is speed and ads. Online converters are slower because they process the video on their servers rather than your computer. Many also display advertisements or ask you to complete surveys before the download starts. Some require you to install browser extensions or software, which defeats the purpose.
Online converters are best for one-off downloads when you don't want to install anything. If you download regularly, a desktop program is faster and cleaner.
Understanding video quality and file size
When you download a video, you choose between quality levels: 360p, 480p, 720p, 1080p, or higher. Higher quality means larger file size and longer download time.
A one-minute video at 720p is roughly 50 to 100 megabytes. At 1080p, it's 100 to 200 megabytes. A full hour at 1080p can be 3 to 5 gigabytes. If you're downloading to a phone or tablet, check how much storage space you have available before choosing the highest quality.
The quality available depends on what the original website offers. YouTube typically offers up to 1080p for most videos, though some have 4K. TikTok videos are usually capped at 720p. Vimeo quality varies by uploader.
Most tools let you choose between MP4 (works on almost everything) and WebM (smaller file size but less compatible). If you're unsure, MP4 is the safer choice.
What to know about terms of service
Before you download, check whether the website allows it. Most video sites prohibit downloading in their terms of service, though enforcement varies widely. YouTube's terms say you can't download videos unless YouTube provides a download button. Netflix, Disney+, and other streaming services explicitly prohibit it.
Some sites allow downloading for personal use but not for sharing or commercial purposes. Others allow it freely. If the video is someone else's creative work, downloading it doesn't give you the right to republish, edit, or sell it—that's a copyright question separate from whether you can download.
In practice, downloading for personal offline viewing is rarely enforced against individual users, but it's worth understanding the rules before you start.
Troubleshooting when downloads fail
If a tool stops working on a site it used to handle, the website has usually updated its code to block downloaders. This happens frequently on YouTube and TikTok. When it does, try a different tool—what fails in one program often works in another because they use different methods to extract the video.
If a download starts but stalls halfway through, check your internet connection. A weak or unstable connection can interrupt large file transfers. Pause and resume if your tool supports it, or start over on a stronger connection.
Some websites block downloads from certain countries or require you to be logged in. If you see an error message, try logging into the website first, then attempt the download again.
If none of your tools work on a particular site, that site may have stronger protections than others. In that case, you may need to look for the video elsewhere, contact the creator to ask for a download link, or accept that it's not available for offline viewing.
Frequently Asked Questions
Is it legal to download videos from YouTube?
YouTube's terms of service prohibit downloading without permission, but the legal question depends on copyright. If you download a video you created or have permission to use, it's legal. If you download someone else's copyrighted work, downloading itself is usually legal—copyright applies to sharing and republishing, not personal use. However, YouTube's terms are a contract separate from copyright law, so violating them could result in your account being suspended.
Why do some downloads fail even though the video plays fine in my browser?
Websites use different technical methods to stream video versus allow downloads. A video that plays in your browser may be protected against downloading, or the download tool may not support that particular site's streaming method. Try a different tool, or check whether the website offers an official download option.
How much storage space do I need for downloaded videos?
A one-hour video at 720p takes roughly 1 to 2 gigabytes. At 1080p, expect 2 to 4 gigabytes per hour. Check your device's available storage before downloading. If you're downloading to a phone, consider downloading to lower quality or deleting videos after you've watched them to free up space.
Can I download videos from TikTok?
Yes, but TikTok actively blocks downloaders. Tools like 4K Video Downloader and SaveFrom.net work intermittently—they may work one week and fail the next as TikTok updates its protections. If one tool fails, try another. TikTok videos are small (usually under 100 megabytes), so the download is fast if it succeeds.
What's the difference between MP4 and WebM format?
MP4 is the standard format that works on nearly every device and player. WebM is smaller but only works on some devices and players. Unless you have a specific reason to use WebM, choose MP4 to ensure the video plays everywhere.
