Introduction
You plug your iPhone into your Windows 11 PC, copy over a folder of photos, and double-click one only to see a message telling you to buy a codec from the Microsoft Store. HEIC files from iPhones do not always open cleanly on Windows, even on the latest version. Microsoft has improved native support over the years, but the experience still depends on which updates you have installed and which app you use. In this guide we walk through the simplest ways to view HEIC photos on Windows 11, from built-in options to a quick conversion trick that sidesteps the whole problem.
Why This Happens
Windows 11 includes the modern Photos app, which can decode HEIC, but only if the HEVC Video Extensions codec is installed. That codec used to cost 99 cents in the Microsoft Store, and even though it is now free on many new Windows 11 installs, older upgraded machines often miss it. Without the codec, the Photos app and most third-party viewers show an error or a blank thumbnail. The underlying issue is licensing. HEVC, the codec inside HEIC, is patented, and Microsoft cannot ship it for free in every market without paying royalties. That is why the codec is a separate download rather than a built-in feature.
3 Solutions
Solution 1: Install the HEVC codec from Microsoft. Search the Microsoft Store for "HEVC Video Extensions." There is a free version from the device manufacturer and a paid version. The free one works for most PCs.
Solution 2: Use a free third-party viewer. Apps like IrfanView, nomacs, or the open-source ImageGlass open HEIC files without the Microsoft codec. Great if you cannot install store apps.
Solution 3: Convert HEIC to JPG before viewing. Run your files through the piczen HEIC to JPG converter in your browser. Then Windows opens them natively with zero setup.
Step-by-Step Guide
If you want to view HEIC files without converting anything, install the codec first. Open the Microsoft Store from your Start menu. Search for "HEVC Video Extensions" and look for the free version labeled as being from the device manufacturer. Click Get and let it install. Once it finishes, open File Explorer, navigate to your HEIC files, and double-click one. The Photos app should now render it. If the Store version does not work or you cannot install Store apps, download ImageGlass from its official site, install it, and set it as your default photo viewer for .heic files. The fastest path if you just need to view a few photos right now is to drop them into the heic to jpg converter, download the JPGs, and open those in any viewer you already have.
Pros and Cons
Installing the codec is the cleanest long-term fix because it lets Windows handle HEIC natively forever after. The downside is the install process and the occasional licensing hiccup on certain Windows editions. Third-party viewers avoid the codec entirely but add another app to your system. Converting to JPG is the most reliable option because it works on any Windows PC, old or new, with no setup at all. For most people who only occasionally receive HEIC files, conversion is the path of least resistance. For heavy iPhone users who copy photos to Windows daily, the codec install pays for itself in saved time.
