HEVC Browser Support
H.265 cuts file sizes in half, but browser support is a battleground.
The Licensing Mess
HEVC (H.265) is heavily patented. Unlike the open AV1 or VP9 codecs, organizations must pay massive licensing pools to include HEVC decoders in their software. Because of this, open-source browsers like Firefox and standard Chromium completely disable HEVC support.
Apple / macOS (Safari)
Apple is a core patent holder for HEVC. As a result, Safari has native, hardware-accelerated HEVC support out of the box. If you are on a Mac, simply open uPlayVideo in Safari and drag an HEVC MKV or MP4 into it. It will play flawlessly, using almost zero battery on Apple Silicon (M1/M2/M3).
Windows (Edge & Chrome)
Microsoft supports HEVC in Edge, but only if you have the HEVC Video Extensions installed at the OS level.
- Open the Microsoft Store.
- Search for "HEVC Video Extensions" (often costs $0.99 due to licensing).
- Once installed, Microsoft Edge will utilize your GPU to natively play HEVC files via uPlayVideo.
Note: Google Chrome historically blocks HEVC even if the OS extension is installed, preferring Google's own VP9/AV1 codecs. Edge is recommended for Windows users watching HEVC.
