How to Download HLS Streaming Videos (M3U8) from Any Website

You find a video online, right-click it, and there's no "Save Video As" option. Or you try saving the page source and can only find a .m3u8 file rather than an MP4. This is HLS — HTTP Live Streaming — and it's the reason most streaming video on the web can't be downloaded with a simple right-click.

HLS is used by Canvas LMS (via Kaltura), Panopto, university lecture systems, corporate training platforms, and thousands of other websites. This guide explains what HLS is, how to find the M3U8 URL, and three methods to download the video as a proper MP4 file.

What Is HLS Streaming and Why Can't You Just "Save As"?

HLS (HTTP Live Streaming) is a streaming protocol developed by Apple and now used across virtually all major video platforms. Instead of serving one large video file, HLS works by:

1. Breaking the video into small segments — typically 2–10 seconds each — stored as .ts files
2. Creating a .m3u8 playlist file that lists the order and URLs of all segments
3. Your browser downloads segments continuously as you watch, rather than downloading the whole file upfront

This design is great for streaming — it adapts quality based on your connection, buffers smoothly, and loads faster than downloading a single large file. But it means there is no single video file to save. Right-clicking and "Save As" just downloads the playlist file, not the video content.

To download an HLS stream, you need a tool that reads the playlist, downloads all the segments, and reassembles them into a single MP4 file. Here are three ways to do that.

How to Find the M3U8 URL

Methods 1 and 2 require you to find the M3U8 URL first. Here's how:

1. Open Chrome and navigate to the page with the video
2. Press F12 (or Ctrl+Shift+I) to open DevTools
3. Click the Network tab
4. Press Ctrl+R to reload the page
5. Start playing the video
6. In the Network filter box, type m3u8
7. Look for a request with a .m3u8 filename — usually labeled something like master.m3u8, playlist.m3u8, or index.m3u8
8. Right-click that request → Copy → Copy URL

Method 1 — Using FFmpeg (Technical Users)

FFmpeg is a free, open-source command-line tool that handles virtually every video format and streaming protocol. It's the most reliable method for downloading HLS streams.

Install FFmpeg:

• Mac: brew install ffmpeg (requires Homebrew)
• Windows: Download from ffmpeg.org and add to your PATH
• Linux: sudo apt install ffmpeg (Ubuntu/Debian)

Download the stream:

Replace the URL with the M3U8 URL you copied from DevTools. The -c copy flag copies the video without re-encoding — faster and preserves the original quality.

If the URL contains an authentication token (you'll see ?token=or similar in the URL), the token may expire. Run the FFmpeg command immediately after copying the URL while the page is still open.

Pros: Reliable, handles all quality levels, widely supported.
Cons: Requires command-line comfort, FFmpeg installation, and finding the URL manually.

Method 2 — Using VLC Media Player

VLC can open network streams, including M3U8 URLs, and record them to a local file. No command line needed.

1. Open VLC and go to Media → Open Network Stream (Ctrl+N)
2. Paste the M3U8 URL into the URL field
3. Click the dropdown arrow next to Play and select Convert
4. In the Convert dialog, choose Video – H.264 + MP3 (MP4) as the profile
5. Set the destination file path (e.g., lecture.mp4)
6. Click Start — VLC downloads and converts the stream to MP4

VLC is slower than FFmpeg because it re-encodes the video. For a 1-hour lecture, expect 10–20 minutes of processing time depending on your CPU. The output quality depends on the profile you select — use a high-bitrate MP4 profile for best results.

Method 3 — Using Canvas Assistant (Simplest)

Canvas Assistant detects HLS streams automatically when a video is playing in your browser. You don't need to find the M3U8 URL or install any additional software.

1. Install Canvas Assistant from the Chrome Web Store
2. Navigate to the webpage with the HLS video and start playing it
3. Click the Canvas Assistant icon in your Chrome toolbar
4. Click Download next to the detected stream
5. The extension downloads all segments and assembles them into a single MP4 file

This method works on Canvas LMS (Kaltura), Panopto, Blackboard, university lecture systems, and most streaming websites that use HLS. For educational platforms specifically, see our guides on downloading Canvas LMS videos and downloading Panopto videos.

Conclusion

HLS streaming is why right-click-save doesn't work on most online videos. To download an HLS stream, you need a tool that reassembles the segments: FFmpeg for full technical control, VLC for a GUI-based approach, or Canvas Assistant for a no-setup browser-based method. All three work for standard HLS streams — DRM-protected content is the one scenario none of them can handle.
