HEIC photos from an iPhone won’t open on Windows by default, but there are several straightforward ways to view them. You can install a small extension from Microsoft, change a setting on your phone, or use a free online tool to convert the files. Here is exactly what to do.

Why Windows Cannot Open HEIC Without Help

Since 2017 and the release of iOS 11, iPhones have saved photos as HEIC by default. HEIC uses HEVC compression, which stores a photo in roughly half the space of a comparable JPEG. That is great for saving storage on your phone, but it uses a file format that Windows 10 and 11 do not support out of the box. Older software and many websites still cannot read HEIC at all, which is why you need to add support or convert the files.

Method 1: Install Microsoft’s HEIF Image Extensions

The simplest way to open HEIC photos directly in Windows is to install Microsoft’s HEIF Image Extensions from the Microsoft Store. This add-on lets Windows File Explorer, the Photos app, and other compatible software read the files natively.

Some systems also need the HEVC Video Extensions, which Microsoft sells for a small fee. If your photos open but show a black or blank image, you likely need that second extension installed too. After both are in place, double-clicking a HEIC file should work just like opening a JPEG.

Method 2: Change IPhone Settings Before Transferring

You can avoid dealing with HEIC files altogether by changing how your iPhone saves or transfers photos. Two settings on the phone give you control.

Automatically Convert When Copying Over a Cable

On your iPhone, go to Settings > Photos > Transfer to Mac or PC and choose Automatic. When you connect your phone to a Windows computer with a USB cable and copy photos, the iPhone will convert them to JPEG on the fly. The files you end up with on your PC will be standard JPEGs that any software can open.

Take All New Photos as JPEG

If you would rather not think about it at all, set your iPhone to capture new photos as JPEG instead of HEIC. Go to Settings > Camera > Formats and select Most Compatible. From that point on, every photo you take will be saved as a JPEG. This does not convert your existing HEIC photos, only new ones.

Method 3: Convert HEIC Files to JPEG or Other Formats

For photos you already have, converting them to a more common format is the most universal solution. You can convert a single file or a whole batch. One practical option is a free HEIC converter that works entirely in your browser and requires no sign-up or installation. It converts iPhone HEIC photos to JPG, PNG, PDF, WebP, AVIF, GIF and TIFF, and can also convert JPG, PNG and WebP back to HEIC if you need that format. The same tool includes an image info and EXIF viewer so you can check metadata without extra software.

Which Method Should You Use?

Each approach has its own trade-offs. Here is a quick comparison to help you decide:

  • Microsoft Extensions are best if you want to keep HEIC files as your primary format and view them directly on Windows. The cost is minimal, and you do not need to change anything on your phone.
  • iPhone Automatic Transfer works well if you regularly copy photos over a cable. It converts only the files you move, leaving the originals as HEIC on your phone.
  • Most Compatible setting is ideal if you prefer JPEG from the start and do not need the storage savings of HEIC. It affects only new photos.
  • Online conversion is useful for occasional use, especially if you need to share a file with someone who cannot open HEIC or if you want a different format like PNG or PDF.

What About Older Windows Versions and Other Software

Microsoft’s HEIF Image Extensions are available for Windows 10 and 11 only. If you are using an older version of Windows, your best bet is to convert the files on your iPhone before transferring them, or use an online converter on a device that can run a modern browser. Many email services, social media sites, and web apps still do not accept HEIC uploads, so converting to JPEG remains a reliable fallback regardless of your operating system.
