HEVC Video Extension 2.5.10

Or a 4K screen recording from a friend's phone shows up as a black frame with audio.

In almost every case the file is fine - what's missing is the H.265/HEVC decoder that Windows leaves out of the box.

The HEVC Video Extension is the official Microsoft package that fills that gap on Windows 10 and Windows 11, and version 2.5.10 is the current release at just 10 MB.

What HEVC Video Extension Does on Windows 10 and 11

Once it is installed, the change is system-wide.

Windows Media Player, the Microsoft Photos app, Movies & TV, File Explorer thumbnails, and any application that talks to Windows Media Foundation can suddenly read .hevc and .h265 video files, render thumbnails for them, and play them back with hardware acceleration on supported GPUs.

There is nothing to configure - the extension registers itself silently and the next file you open just works.

Opening iPhone HEIC Photos on Windows

The same install also unlocks Apple's photo format. .HEIC files - the format the iPhone has saved photos in by default since iOS 11 - use HEVC compression for the actual image data inside a HEIF container. Windows can read the container on its own, but it cannot decode the compressed image until HEVC is present.

Pair the extension with the HEIF Image Extensions package (or the standalone HEIC Image Extension) and your iPhone photos open in the Photos app instantly, complete with thumbnails in File Explorer.

If you only have a one-off batch to deal with rather than a permanent setup, browser-based tools to convert HEIF to JPEG and convert JPEG to HEIF get the job done without installing anything, and CopyTrans HEIC adds right-click HEIC conversion directly inside Windows.

Hardware Acceleration for 4K and HDR Playback

Hardware support matters most for 4K and HDR content. The extension is designed to take advantage of dedicated HEVC decoding silicon on Intel 7th-generation Core processors and newer, recent NVIDIA GeForce cards, and AMD GPUs with modern UVD or VCN blocks.

On those machines, 4K Ultra HD HEVC playback runs entirely on the GPU with minimal CPU load. Older hardware falls back to software decoding, which is fine for 1080p clips on most modern systems but can stutter on 4K.

The guide Is my PC able to play H.265/HEVC media files? walks through exactly what to check on your machine before you commit to building an HEVC library.

How to Download HEVC Video Extension for Free

The package requires Windows 10 build 17763 (October 2018 Update) or later, which covers every supported Windows 10 and Windows 11 release.

Microsoft does not list this version on the Store for direct download from a browser - the working free path is documented step by step in How to Download HEVC Video Extension for Free, which uses an official Microsoft Store link generator and produces the same signed package you would get if Microsoft offered it directly.

The alternative free channel is the OEM build, HEVC Video Extensions from Device Manufacturer, which is identical in functionality and is the same file Microsoft ships pre-installed on hardware from Dell, HP, and Lenovo.

Alternative: Media Players With Built-in HEVC Support

For users who would rather skip Microsoft Store extensions entirely, a media player with its own internal decoder solves the same problem at the application level.

VLC Media Player handles HEVC out of the box on Windows 10 and 11 with no extras needed, and the dedicated guide on Playing HEVC Files on VLC Media Player covers hardware acceleration setup for high-bitrate 4K files.

PotPlayer and MPC-HC ship with the same FFmpeg-based decoders and play H.265 files immediately on a clean Windows install - the walkthrough on How to Play HEVC/H.265 Files with PotPlayer covers the renderer and decoder choices that actually matter.

If you want decoder support system-wide so editing apps, older Windows Media Player builds, and any other DirectShow-aware program can read HEVC, the K-Lite Codec Pack bundles LAV Filters and the rest of the decoder stack in a single installer.

The lighter libde265 Filters package is a focused alternative for H.265/HEVC inside Matroska and WebM containers when you want a minimal install.

Quick HEVC Playback Directly in a Browser

If you just need to check a single HEVC file quickly without installing anything at all, the browser-based HEVC Player plays H.265 video directly in Chrome, Edge, or Safari and includes a built-in MP4 rewrapper for browsers that cannot decode HEVC natively.

Encoding HEVC Videos on Windows

For encoding rather than playback, the extension exposes a software encoder on devices without dedicated HEVC hardware, but its output is best treated as a convenience for casual conversions rather than a serious archiving tool. For that work the x265 Encoder remains the open-source standard and produces noticeably better quality at the same bitrate than any system-level encoder.

The DivX HEVC Encoder is another option for users already inside the DivX workflow, although its active development stopped years ago. For a full project-based encoding workflow with frame-accurate trimming and audio handling, the walkthrough on Encoding HEVC Videos Using StaxRip covers the modern toolchain end to end.

Related Windows Extensions and Further Reading

Adjacent formats are worth setting up at the same time as HEVC.

The AV1 Video Extension does for AV1 what this package does for H.265 - YouTube, Netflix, and Meta are all moving significant parts of their libraries to AV1, and Windows does not ship with an AV1 decoder either.
