FAQ
Does Video Downloader Pro Work on All Websites?
Quick Answer
Mostly — yes. Video Downloader Pro detects video on virtually any site that uses standard HTML5 video, MP4, WebM, HLS, or DASH delivery. It does not need site-specific support. What it cannot reach: DRM-protected services (Netflix, Disney+, HBO Max, Hulu, Apple TV+), YouTube (Chrome Web Store policy prohibits extensions from capturing YouTube video), and some live-stream protocols that never produce a file. If you can play it in a standard HTML5 player, you can usually save it.
- Works on most websites that serve unencrypted video via standard delivery: HTML5 video, MP4, WebM, HLS (.m3u8), and DASH.
- Does NOT work on DRM-protected streaming services (Netflix, Disney+, HBO Max, Hulu, Apple TV+) — encryption prevents stream capture by any extension.
- YouTube is excluded by Chrome Web Store program policies, which prohibit extensions from facilitating YouTube video downloads.
- If the badge on the extension icon shows 0 videos on a page, the video is likely DRM-protected, on YouTube, or using a non-standard delivery method.

How Video Detection Works
Video Downloader Pro monitors network requests in your browser tab. When it detects a video file being loaded (MP4, WebM, M3U8 streams, or other standard formats), it captures the URL and makes it available for download. The extension works with standard HTML5 video players, direct file links, and many streaming protocols. It does not need to know about the specific website in advance — if the video data is accessible as a standard file or stream, the extension can detect it.
Websites Where It Works Well
Video Downloader Pro has broad compatibility with websites that use standard video delivery methods.
- Social media platforms — Most social platforms serve videos in standard formats that can be detected
- News and media sites — CNN, BBC, Reuters, and most news outlets use standard HTML5 video players
- Educational platforms — Khan Academy, Coursera (non-DRM lectures), and many educational video hosts
- Blogs and personal sites — WordPress, Squarespace, Wix, and other website builders use standard video embeds
- Video hosting platforms — Vimeo (where download is permitted by the uploader), Dailymotion, and similar platforms
- Corporate and marketing sites — Product demos, webinars, and marketing videos hosted on company websites
- Forums and communities — Reddit video embeds, Discord shared videos, and community platform content
Websites Where It Does Not Work
Some websites use technologies that prevent browser-based download tools from accessing the video content. See our DRM FAQ for details on encrypted content.
- DRM-protected streaming services — Netflix, Disney+, Amazon Prime Video, HBO Max, Hulu, Apple TV+ (encrypted content)
- YouTube — YouTube uses specialized streaming that Chrome Web Store policies prohibit extensions from capturing. See why YouTube downloads are restricted.
- Some live streaming platforms — Certain live stream implementations use real-time protocols that are not captured as downloadable files
- Platforms with token-expiring URLs — Some sites generate video URLs that expire within seconds, making the captured URL invalid by the time you click download
Troubleshooting When Videos Are Not Detected
If Video Downloader Pro does not detect a video on a specific website, there are a few things to check before concluding the site is incompatible.
- Wait for the video to start playing — The extension detects videos as they load. If you have not started playback, there may be nothing to detect yet.
- Check the extension icon — A badge number on the icon indicates how many videos have been detected on the current page. If it shows 0, the video may be DRM-protected or using an unsupported delivery method.
- Try refreshing the page — Sometimes the extension needs to be present when the page initially loads to capture the video request
- Check for multiple quality options — Some sites serve videos in multiple qualities. The extension may detect several versions — choose the one with the resolution you prefer. For 4K downloads, see our 4K download guide.
