HEVC Video Extensions Free: Windows Options Compared

Compare Microsoft HEVC extensions, Media Feature Pack, VLC, LAV Filters, FFmpeg, and browser-based HEVC playback for Windows.

Last updated: 2026-07-25

Is there a free HEVC Video Extension for Windows?

The honest answer is: there is no Microsoft source we can verify as a universal, free HEVC extension download for every Windows PC.

Microsoft currently exposes two separate Store product records:

HEVC Video Extensions (9NMZLZ57R3T7) is the normal consumer listing. It is available for purchase, and the US Store showed a price of $0.99 when we checked on July 25, 2026. The exact price is set by Microsoft Store and varies by market.
HEVC Video Extensions from Device Manufacturer (9N4WGH0Z6VHQ) is an official Microsoft catalog item with a zero price in its metadata. However, the same catalog currently disables ordinary browsing, purchase, and web download for this item in the US, UK, Germany, Japan, and China storefronts we checked.

That makes the second item a possible device or account entitlement, not a dependable free download for everyone. If Microsoft Store offers an Install button on your Windows device, you can use it. If it does not, there is no safe reason to bypass the Store with an unofficial APPX mirror.

Research status: We checked the live Microsoft Store listings and current Microsoft support documentation on July 25, 2026. Store price, availability, and entitlement can change by country, device, account, and time.

HEVC solution and capability comparison

The word “extension” is used loosely online. The options below are not interchangeable: some add a codec to Windows, some play files only inside their own application, and some are developer libraries that require a complete player around them.

In the tables, Windows apps means integration with Media Player, Photos, and other compatible Windows media-stack applications. Browser-native means the browser can use its normal <video> pipeline; displaying video inside a custom website or extension player is a separate capability.

Ready-to-use options for Windows users

Capability comparison of ready-to-use HEVC playback solutions for Windows
Solution	What it is	Cost	Windows apps	Chrome / Edge native video	Hardware acceleration	Best use
Microsoft HEVC Video Extensions	Official Windows codec package	Paid; market-specific	Yes, for supported files	Edge: expected Windows path; Chrome: not guaranteed	Yes, on supported hardware	Native Windows and Edge integration
HEVC Video Extensions from Device Manufacturer	Restricted Microsoft codec entitlement	Free when eligible	Yes, after an entitled installation	Edge: conditional; Chrome: not guaranteed	Yes, on supported hardware	Eligible OEM devices or accounts
Media Feature Pack	Optional Windows feature for N editions	Free	Restores missing media components; HEVC may still need the Store extension	Indirect only	Depends on the installed codec and device	Windows 10 N and Windows 11 N only
OpenHEVCVideo	Local web player with native-first and WASM fallback paths	Free	No system-wide codec	Plays inside this site; does not add HEVC to every website	Native path may use hardware; WASM fallback uses CPU	Private, no-install local playback
VLC media player	Open-source desktop player	Free	No system-wide codec	No	Available on compatible hardware	Broad offline desktop playback
LAV Filters	GPL-2.0 DirectShow splitter and decoders	Free	DirectShow applications only	No	Available through supported DXVA / D3D11 paths	MPC-style and other DirectShow players

Open-source components for developers

These projects can be used to build a player or compatibility layer. None is a ready-made Microsoft Store HEVC extension, and none should be presented as a drop-in replacement for the licensed Windows package.

Capability comparison of open-source HEVC decoder components
Project	License	Primary role	Browser / WASM path	Windows system extension	Important boundary
hevc.js	MIT	Browser HEVC decoder and client-side compatibility pipeline	Ready browser-focused WASM packages	No	Software HEVC work is CPU-intensive; validate each profile and device
FFmpeg / libavcodec	LGPL 2.1+ by default; GPL when GPL components are enabled	Broad demuxing and software decoding framework	Possible through a custom trimmed WASM build	No	You own the player UI, build, bundle size, and license compliance
libde265	LGPL	Standalone C HEVC decoder	Possible with a custom build	No	The upstream README explicitly guarantees the HEVC Main profile
Ittiam libhevc	Apache-2.0	Native HEVC encoder and decoder library	Requires custom porting and integration	No	Official build targets list Linux, Android, and macOS rather than Windows

Windows provides APIs for registering a custom Media Foundation Transform, so a team could wrap an open-source decoder in a Windows codec product. That remains a substantial engineering, testing, signing, distribution, and licensing project. We found no maintained open-source package that can be installed as a verified drop-in replacement for Microsoft HEVC Video Extensions in Edge and Windows media apps.

Open-source software terms also do not automatically settle HEVC patent obligations. Review the project license and distribution model separately; FFmpeg’s legal guidance explains this distinction without offering legal advice.

Verified official Microsoft Store options

1. HEVC Video Extensions — the normal paid listing

This is the primary Microsoft extension for adding HEVC/H.265 support to the Windows media stack. Microsoft describes it as enabling HEVC playback in Windows video apps and says it can use supported hardware for 4K and Ultra HD playback, with software support available on other devices at potentially different performance levels.

Publisher: Microsoft Corporation
Product ID: 9NMZLZ57R3T7
Availability: publicly browsable and purchasable in the markets we checked
Price: market-specific; the US listing showed $0.99 on July 25, 2026

Open HEVC Video Extensions directly in the Windows Store app

Use this option when you want the best chance of integrating HEVC with Windows apps such as Media Player and Photos, or with browser paths that depend on the Windows media stack. It is still not a guarantee that every HEVC file will play.

2. HEVC Video Extensions from Device Manufacturer — free only when eligible

The device-manufacturer listing is real and is published by Microsoft Windows. Its official product record currently reports a zero price, but it is not operating as an ordinary public download page. Microsoft does not publish a clear, current consumer eligibility matrix on that page.

Publisher: Microsoft Windows
Product ID: 9N4WGH0Z6VHQ
Catalog price: zero
Public availability: normal browsing, purchase, and web download are currently disabled in the markets we checked

Check the device-manufacturer listing on Microsoft Store

Ask the Windows Store app to open the OEM product page

The Store app may show Install if your device or Microsoft account already has the required entitlement. It may instead show that the product is unavailable. Both outcomes are consistent with a restricted catalog item. We do not describe this as a guaranteed free download.

3. Media Feature Pack — only for Windows N editions

The free Media Feature Pack is frequently confused with the HEVC extension. It applies only to Windows 10 N and Windows 11 N, which omit parts of the normal Windows media platform.

Microsoft says the pack restores media technologies and standards-based codec components, including H.265-related functionality. The same support page also lists HEVC Video Extensions as an additional Microsoft Store app that may be installed after the pack. Therefore:

install Media Feature Pack if your edition name ends in N;
do not install it as a codec workaround on a normal Windows edition;
do not assume it is identical to the Store HEVC extension.

Free ways to open an HEVC video without the Windows extension

Use OpenHEVCVideo in your browser

If your goal is simply to inspect or play a local file, you do not have to install a system extension first. Return to the OpenHEVCVideo player, select one or more local HEVC files, and let the site test the actual file.

The player first attempts browser-native playback. If that path is unavailable, it can try a browser-based compatibility path that software-decodes supported HEVC video locally with WebAssembly. Your selected video remains in the local browser session rather than being uploaded for server-side conversion.

Native playback is preferred when it works because it usually uses less CPU, consumes less battery, and handles high-resolution video more smoothly. Compatibility mode is the no-install fallback, not a promise of desktop-player performance for every 4K, HDR, high-bitrate, or unusual file.

Use VLC as a free desktop player

VLC from VideoLAN is a legitimate, free, open-source Windows player with HEVC support. It is a strong alternative when you need broad desktop playback or want to work offline.

VLC is not a replacement Windows codec extension. Installing VLC lets VLC use its own playback components; it does not prove that Photos, Media Player, Edge, or another Windows app can decode the same file.

Can a website detect that the HEVC extension is installed?

Not directly. Standard browser APIs do not reveal the list of Microsoft Store packages installed on a PC. A site can query or test media capability, but that is different from identifying a specific Windows package.

For example, MediaCapabilities.decodingInfo() can report whether a particular codec configuration appears supported, smooth, and power-efficient. A video element can also report likely format support. These results describe the browser-device combination, not the identity of the installed decoder.

OpenHEVCVideo therefore follows a more defensible process:

inspect the selected file and its media tracks;
ask the current browser about the relevant HEVC configuration;
attempt playback of the real local file;
use native playback when it succeeds;
prepare compatibility mode when native playback fails.

A successful native test does not prove the Microsoft extension is installed, because another hardware or platform decoder may be responsible. An installed extension also does not prove that a particular file will work.

What Chrome and Edge actually depend on

Microsoft currently documents HEVC in Edge as conditionally supported. Edge uses the Windows MediaFoundationVideoDecoder path and requires a valid HEVC decoder path. Microsoft also warns that an extension installed from a third-party platform can have an invalid license and fail in Edge.

Chromium’s current media documentation lists HEVC support in Google Chrome on Windows 11 22H2 or later as requiring hardware support. Chrome and Edge can therefore produce different results on the same PC. Installing the Microsoft extension may improve the native path for some Windows and Edge configurations, but it should never be marketed as a universal Chrome fix.

For a broader explanation, read HEVC Player for Windows and the HEVC compatibility guide.

Safe installation and verification steps

Open Settings > System > About and confirm whether your Windows edition includes the letter N.
Open Settings > Apps > Installed apps and search for “HEVC Video Extensions.” You may already have the paid or device-manufacturer package.
If it is missing, use one of the official Microsoft Store links above. Verify the exact product ID and the Microsoft publisher before installing.
If the OEM page offers Install, use the Store-managed installation. If it does not, choose the standard paid listing or a no-extension alternative.
Finish pending Windows, Store, browser, and graphics-driver updates.
Restart Chrome or Edge, then test the same local file again. The browser needs a fresh capability and playback probe after the system decoder changes.

Advanced users can perform a read-only package check in PowerShell:

Get-AppxPackage -AllUsers *HEVC* | Select-Object Name, PackageFullName

This command can confirm that Windows knows about an HEVC package. It still cannot guarantee that the package license, browser decoder path, file profile, audio track, and GPU driver all work together.

Why an installed extension may still not play a file

HEVC identifies the video compression method, not the entire file. Playback can still fail because of:

an unsupported MP4, MOV, MKV, or raw-stream layout;
a HEVC profile, bit depth, level, chroma format, or resolution outside the available decoder;
an audio track such as AC-3 or E-AC-3 that the browser cannot decode;
HDR or DRM requirements;
damaged metadata or an incomplete file;
an outdated GPU driver or disabled hardware acceleration;
a valid extension installed for one Windows account but not correctly licensed for the current path.

Test the exact file instead of treating its .mp4, .mov, .mkv, .hevc, or .h265 suffix as proof of support.

Why we do not link to APPX mirrors or codec packs

Microsoft’s codec guidance warns that broad codec packs found online can cause serious playback problems, conflicts, and even system corruption. Microsoft’s Edge documentation also says that a third-party HEVC extension installation may carry an invalid license.

For that reason, this page links only to:

Microsoft Store and Microsoft Support;
the official VideoLAN website;
this site’s local browser player.

We do not host, mirror, or recommend copied APPX, MSIX, APPXBUNDLE, registry patches, or scripts that attempt to bypass Microsoft Store entitlement.

Frequently asked questions

Is HEVC Video Extensions from Device Manufacturer really free?

Its official Microsoft catalog record has a zero price, so it is free when Microsoft makes it available to an entitled device or account. The current public listing does not offer ordinary browsing, purchase, or web download in the markets we checked, so it is not a universal free offer.

Why does the OEM link say unavailable?

The product record can exist while acquisition is restricted. Your device, account, region, Windows edition, or prior entitlement may determine what the Store app displays. An unavailable result is not a reason to download the package from an unofficial mirror.

Can I download the free OEM APPX directly?

We found no current Microsoft page offering a universal direct APPX or MSIX download for consumers. The supported public route is the Microsoft Store product page or Store app URI. Enterprise offline Store packaging has separate licensing and administration requirements and is not a consumer workaround.

Is the paid Microsoft extension a one-time purchase?

The Store presents the standard item as an app purchase tied to the acquiring Microsoft account. Confirm the current terms, local price, and device availability in your Store before buying.

Will installing the extension make HEVC work in Chrome?

Not necessarily. Google Chrome’s HEVC path on Windows depends on the Chrome build, Windows version, hardware, driver, and exact video configuration. The extension may help some platform paths, but the real file must still be tested.

Will installing it make HEVC work in Edge?

It can provide the valid Windows decoder path Edge expects, but container, profile, audio, HDR, DRM, driver, and package-license issues can still cause failure. Use edge://media-internals and edge://gpu for advanced diagnosis.

Do I need HEIF Image Extensions too?

HEIF Image Extensions are for HEIF/HEIC images. HEVC Video Extensions provide HEVC video decoding used by video workflows and by some HEIF content. They are related but not interchangeable.

What is the best completely free choice?

Use OpenHEVCVideo when you want a private, no-install browser workflow for a supported local file. Use official VLC when you want a mature desktop player. Neither option installs Microsoft’s system-wide HEVC extension.
