HEVC Video Extensions: How to Play H.265 Videos on Windows & Mac
HEVC Video Extensions: How to Play H.265 Videos on Windows & Mac
You just received an HEVC video, double-clicked it, and… nothing plays. Or you see audio with a black screen. This is one of the most common video headaches, and the fix usually involves HEVC Video Extensions — a codec package that lets your device decode H.265 files.
In this guide, we'll explain what HEVC Video Extensions are, how to install them on Windows, how playback works on Mac, and what to do when installing extensions isn't an option.
What Are HEVC Video Extensions?
HEVC (High Efficiency Video Coding), also known as H.265, is a modern video codec that compresses video to roughly half the size of the older H.264 standard at the same quality. It's used by iPhones (in "High Efficiency" mode), 4K cameras, and streaming services because it saves enormous amounts of storage and bandwidth.
The trade-off: HEVC isn't natively supported everywhere. On Windows, you need the HEVC Video Extensions — a small add-on from the Microsoft Store that installs the H.265 decoder so apps like Movies & TV, Photos, and Media Player can play these files.
To understand why HEVC exists and how it compares to older codecs, read our HEVC vs H.264 comparison and our HEVC codec explained guide.
How to Install HEVC Video Extensions on Windows
There are two versions of the extension in the Microsoft Store, and this trips a lot of people up.
Option 1: HEVC Video Extensions from Device Manufacturer (Free)
Microsoft offers a free version called HEVC Video Extensions from Device Manufacturer. It's the same decoder as the paid version but is meant to be bundled by hardware makers. You can often install it directly:
- Open this link in your browser: search the Microsoft Store for "HEVC Video Extensions from Device Manufacturer"
- Click Get or Install
- Once installed, HEVC videos should play in the Movies & TV app and Photos
If the free version isn't available in your region, you'll see the paid listing instead.
Option 2: HEVC Video Extensions (Paid, ~$0.99)
The standard HEVC Video Extensions listing in the Microsoft Store costs about $0.99. It's identical in function to the manufacturer version.
- Open the Microsoft Store
- Search for HEVC Video Extensions
- Click Buy ($0.99) and complete the purchase
- Restart your video app and try playing the file again
Verify HEVC Playback
After installing, open an HEVC file in Movies & TV or Photos. If it plays with both video and audio, you're set. Still stuck? A codec conflict or an unsupported audio track may be the culprit — converting the file (below) is the reliable fallback.
Playing HEVC Videos on Mac
Good news for Mac users: macOS supports HEVC natively on any Mac from 2017 onward (macOS High Sierra and later). You don't need to install any extensions. HEVC videos play in:
- QuickTime Player — Apple's built-in media player
- Photos — for HEVC clips from your iPhone
- Preview — for quick previews
- Final Cut Pro, iMovie — for editing
If an HEVC file won't play on an older Mac, or you need to share it with someone on Windows without the extensions, the simplest solution is to convert it to H.264.
When to Convert HEVC Instead
Installing codec extensions isn't always practical — maybe you're sending a video to a client, uploading to a platform that rejects H.265, or working on hardware that can't decode it. In those cases, converting HEVC to the universally compatible H.264/MP4 format is the fastest fix.
Convert HEVC on Mac with Compresto
Compresto converts HEVC (H.265) videos to H.264 MP4 with hardware acceleration, so even large 4K files convert quickly. Drag the file in, choose H.264 output, and you get a version that plays on any device — no extensions required.
Steps:
- Open Compresto on your Mac
- Drag in your HEVC video
- Choose MP4 (H.264) as the output format
- Click compress/convert and save the universally compatible file
For a full walkthrough, see our guide on converting HEVC to H.264.
Other Conversion Options
- HandBrake — free, cross-platform; select the H.264 preset and encode
- VLC — use Media > Convert/Save with an H.264 profile
- FFmpeg —
ffmpeg -i input.mp4 -c:v libx264 -crf 23 -c:a aac output.mp4

Frequently Asked Questions
Why won't my HEVC video play on Windows?
Windows doesn't include the H.265 decoder by default. Install HEVC Video Extensions (or the free from Device Manufacturer version) from the Microsoft Store to enable playback.
Are HEVC Video Extensions free?
There's a free version called HEVC Video Extensions from Device Manufacturer and a paid version (~$0.99). Both use the same decoder. macOS includes HEVC support for free.
Do I need HEVC extensions on Mac?
No. Macs from 2017 onward (macOS High Sierra and later) support HEVC natively in QuickTime, Photos, and Preview.
Is HEVC the same as H.265?
Yes. HEVC (High Efficiency Video Coding) and H.265 are two names for the same video compression standard. It succeeds H.264/AVC and compresses video about twice as efficiently.
How do I convert HEVC to a more compatible format?
Convert HEVC to H.264 MP4 using Compresto, HandBrake, VLC, or FFmpeg. H.264 plays on virtually every device without extra codecs. See our HEVC to H.264 guide.
Does HEVC lose quality when converted to H.264?
Converting between codecs is re-encoding, so there's minor quality loss. Using a high quality setting (CRF 18–20) keeps the difference visually imperceptible. Files will be larger than HEVC but more compatible.
Play HEVC Files Anywhere
HEVC Video Extensions solve playback on Windows, and Mac handles H.265 out of the box — but when you need a file that just works everywhere, converting to H.264 is the surest path. Compresto makes that conversion fast and painless on your Mac.
