App overview
VP9 Video Extensions is a free Windows add-on from Microsoft that provides native support for playing videos encoded with the VP9 codec. Designed to simplify video playback, it supplies the necessary codec so VP9-encoded files can be handled directly by the operating system.
Key functions
- Enables playback of VP9-encoded video files without installing third-party players.
- Offers efficient compression support commonly used for high-quality streaming.
- Keeps resource usage light while preserving visual detail during playback.
How it works with Windows
Once installed, the extension registers the VP9 codec with Windows so users can open VP9-encoded files by double-clicking them in File Explorer. This removes the need to hunt for separate codec packs or alternate media players, ensuring smoother, system-level handling of compatible videos.
Who benefits
This extension is useful for Windows users who frequently encounter VP9-formatted media and want a straightforward, reliable playback experience. Because it’s distributed by Microsoft, it integrates cleanly with the OS and is maintained to work with standard Windows media frameworks.
Suggested alternative
- HEVC Video Extensions (paid) — a recommended paid option if you need support for HEVC/H.265 content in addition to or instead of VP9.
