To open a HEIC file on Windows, you must first install Microsoft's HEIF image extension, secondly, you can use a third-party viewer or conversion tool, and finally you can set the automatic conversion format through your iPhone. The specific steps are: 1. Go to the Microsoft store to search and install "HEIF Image Extensions", and after installation, you can use the photo application to view the HEIC file; 2. Use third-party tools such as XnConvert, FastStone Image Viewer, or IrfanView with the HEIC plug-in to perform more flexible viewing and conversion; 3. Select the "Auto" transfer format in the "Photo" settings of the iPhone, so that the pictures are converted to JPEG format before being transferred to Windows, ensuring compatibility.

Opening HEIC files on Windows can be a bit tricky if you're used to more common image formats like JPEG or PNG. HEIC is Apple's default format for photos taken on iPhones running iOS 11 and later, and while it's efficient and high-quality, Windows doesn't support it natively by default — at least not in the most straightforward way.

Here's how you can actually open and view HEIC files on a Windows PC without too much hassle.

Install the HEIF Image Extension from Microsoft

Windows 10 and 11 do have support for HEIC files — but only if you install an optional codec pack. Microsoft provides a free HEIF (High Efficiency Image File) extension that enables basic viewing of HEIC files in the Photos app.

• Go to the Microsoft Store .
• Search for "HEIF Image Extensions" .
• Click Get to install it.

Once installed, you should be able to double-click HEIC files and view them in the Photos app. This works well for casual browsing, but don't expect advanced features like editing or conversion unless you use additional tools.

Use a Third-Party Viewer or Converter

If installing the Microsoft extension isn't enough or you want more flexibility, there are several third-party apps that handle HEIC files better.

Some popular options:

• XnConvert – Free and supports batch conversion.
• FastStone Image Viewer – Lightweight and supports many formats including HEIC after installing additional codecs.
• IrfanView with HEIC plugin – One of the most flexible freeware views, but requires a separate plugin installation for HEIC support.

These tools often let you convert HEIC files to more compatible formats like JPG or PNG, which might be useful if you need to share the images with others who don't have HEIC support.

Convert HEIC Files Automatically from iPhone

If you're regularly transferring HEIC photos from your iPhone to a Windows PC, consider changing the format before they even reach your computer.

When you send photos via email, AirDrop (to a Mac), or upload them to iCloud.com, you can set your iPhone to automatically convert HEIC files to JPEG:

• Open the Settings app.
• Go to Photos .
• Under "Transfer to Mac or PC", select "Automatic" or "Keep Originals" depending on your needs.

Choosing "Automatic" will convert HEIC files to JPEG when you transfer them, making them instantly compatible with Windows.

All in all, opening HEIC files on Windows isn't hard once you know what tools to use. The Microsoft Store extension covers basic needs, while third-party tools offer more control. And if you're sending a lot of photos from your iPhone, converting them before transfer makes things smoother.

That's basically it — not complicated, just something Windows users might overlook until they run into their first HEIC file.
