The simplest way depends on what site you're downloading from

Most video downloads work one of three ways: using a browser extension, pasting the video's link into a dedicated downloader tool, or using command-line software if you're comfortable with that. Which method works best depends on whether the site lets you download directly, whether it blocks downloaders, and what format you want the video in.

Before you download anything, check the site's terms of service. Some platforms — like Netflix, Disney+, and YouTube — have their own download features built in for offline viewing. Using those is simpler and legal. For other sites, downloading is usually permitted for personal use, but not for redistribution or commercial purposes.

Key Takeaways

  • YouTube, Netflix, and similar platforms have built-in download features; use those instead of third-party tools when available.
  • Browser extensions like Video DownloadHelper work on most sites but may not work if a site actively blocks them.
  • Paste-and-download tools like y2mate or SaveFrom require only the video's URL and work in your browser without installing anything.
  • Command-line tools like yt-dlp are more powerful and flexible but require you to type commands rather than click buttons.
  • Downloaded videos may be in formats your device doesn't play; you may need to convert them using free software like HandBrake or FFmpeg.

Using built-in download features on major platforms

YouTube, Netflix, Disney+, Amazon Prime Video, and most major streaming services let you download videos directly through their apps or websites. This is always the easiest route when it's available. On YouTube, the download button appears below the video on the mobile app (not the website). On Netflix, you can download most titles through the app by tapping the download icon next to the play button. On Disney+ and Prime Video, look for a similar download icon.

These built-in downloads are designed to work offline on your device and usually expire after a set period — Netflix downloads expire after 30 days, for example. The video stays in the app and doesn't create a file you can move around or edit. If you need the video as a standalone file, you'll need a different method.

Browser extensions for downloading from most websites

Video DownloadHelper is the most widely used browser extension for this task. It works on Firefox and Chrome, and it detects video players on almost any website you visit. When you land on a page with a video, an icon appears in your browser toolbar showing what videos are available. Click it, choose the format and quality you want, and the download starts.

Other extensions like 4K Video Downloader and Downie (Mac only) work similarly. The advantage of extensions is that they're always running — you don't have to navigate to a separate website or paste links. The disadvantage is that some sites actively block them, and you have to install software on your computer.

To install Video DownloadHelper on Firefox: go to addons.mozilla.org, search for "Video DownloadHelper", click Add to Firefox, and confirm. On Chrome, visit the Chrome Web Store, search for the extension, and click Add to Chrome. Once installed, visit any page with a video and look for the extension icon in your toolbar.

Paste-and-download tools that work in your browser

Sites like y2mate.com, SaveFrom.net, and TubeMate let you download videos without installing anything. You copy the video's URL from your browser's address bar, paste it into the downloader's website, choose your format and quality, and click download. The video file appears in your Downloads folder.

These tools work on most sites, including YouTube, TikTok, Instagram, Vimeo, and Facebook. They're useful if you're on a shared computer or don't want to install extensions. The trade-off is that you have to visit a third-party website each time, and some of these sites display ads or may ask you to install browser toolbars (which you should decline).

To use y2mate: go to y2mate.com, paste your video URL into the search box, select the format (MP4 is most compatible), choose quality, and click Download. The file downloads to your computer's default Downloads folder. You can then move it anywhere you want.

Command-line tools for power users

yt-dlp is a command-line tool that downloads videos from hundreds of sites, including YouTube, TikTok, Instagram, Vimeo, and many others. It's free and open-source, and it's more flexible than browser extensions or paste-and-download sites. You can download entire playlists, choose specific video quality, extract just the audio, or convert to different formats — all from one command.

The downside is that it requires you to use your computer's terminal or command prompt, which intimidates many people. If you're comfortable opening a terminal and typing commands, yt-dlp is worth learning. If not, stick with the browser extension or paste-and-download methods above.

To install yt-dlp on Windows: download the .exe file from github.com/yt-dlp/yt-dlp/releases, save it to a folder, open Command Prompt in that folder, and type yt-dlp [video-url]. On Mac or Linux, install it via Homebrew or pip, then use the same command. The video downloads to your current folder.

Converting videos to formats your device can play

Downloaded videos may be in formats like .mkv, .webm, or .flv that your phone or tablet doesn't recognize. HandBrake is free software that converts almost any video format to MP4, which plays on nearly every device. Download it from handbrake.fr, open the video file, choose your output format (MP4 is the safest choice), and click Start.

If you need just the audio — for example, to extract music from a YouTube video — FFmpeg is a command-line tool that does this quickly. On Windows, download ffmpeg from ffmpeg.org, and run a command like ffmpeg -i video.mp4 -q:a 0 -map a audio.mp3. On Mac, install it via Homebrew and use the same command.

For most people, HandBrake is easier because it has a graphical interface. For power users or batch conversions, FFmpeg is faster.

What to do when a site blocks downloaders

Some sites use technology that prevents extensions and paste-and-download tools from working. If you try to download and get an error, the site is likely blocking you. In this case, your options are limited: use the site's built-in download feature if it has one, or record the video as it plays using screen recording software.

OBS Studio (Open Broadcaster Software) is free screen recording software that works on Windows, Mac, and Linux. Open it, set up a recording region around your video player, click Start Recording, play the video, and click Stop when finished. The video saves as an MP4 file. This method is slower and the quality depends on your internet speed, but it works on almost any site.

Frequently Asked Questions

Is it legal to download videos from YouTube?

YouTube's terms of service say you can't download videos unless YouTube provides a download button. However, downloading for personal, non-commercial use is often treated differently in practice than the terms suggest. If you want to be certain, use YouTube's built-in download feature on the mobile app, which is explicitly permitted.

What's the difference between MP4, MKV, and WebM?

MP4 is the most compatible format — it plays on phones, tablets, computers, and most media players. MKV and WebM are less common and may not play on all devices. If you download a video in MKV or WebM and your device won't play it, convert it to MP4 using HandBrake.

Can I download videos from Instagram or TikTok?

Yes, using browser extensions, paste-and-download sites, or yt-dlp. Copy the video's URL from your browser, paste it into y2mate or SaveFrom, and download. Note that Instagram and TikTok's terms of service restrict downloading, so this is a gray area — check their policies if you plan to share the video publicly.

Why is my downloaded video so large?

Video files are large by default. A one-hour video in 1080p quality is typically 1 to 3 gigabytes. If you need a smaller file, download in lower quality (480p or 720p instead of 1080p), or convert it using HandBrake and choose a lower bitrate.

Do I need to worry about viruses from downloader sites?

Reputable sites like y2mate and SaveFrom are generally safe, but avoid clicking ads or downloading toolbars they offer. Stick to well-known tools like Video DownloadHelper, HandBrake, and yt-dlp, which are open-source and widely reviewed. If you're unsure about a site, use a browser extension instead.
