How to Open HEIC Files - Complete Guide for Windows, Mac, and iPhone
Last updated: January 10, 2026
Have you ever tried to open a HEIC file taken with your iPhone on a Windows PC, only to find that the file won't open or display? This guide explains why HEIC files can't be opened and provides detailed methods for opening HEIC files on Windows, Mac, iPhone, and other platforms.
Why Can't HEIC Files Be Opened?
HEIC (High Efficiency Image Container) is an image file format adopted by Apple starting with iOS 11. While this format offers excellent compression efficiency and superior image quality, its biggest issue is 'compatibility'.
Windows computers cannot open or display HEIC files by default. This is because Windows does not natively support the HEIC format. Similarly, HEIC files may not be able to be opened on Android devices and some older devices.
Since HEIC format was introduced by Apple in 2017 as a relatively new format, not all devices and software support it yet. Particularly on Windows 10 and earlier versions, HEIC files cannot be opened without installing special extensions or software.
How to Open HEIC Files on Windows
There are several methods to open HEIC files on Windows. Each method has its advantages and disadvantages, so choose the one that best fits your situation.
Method 1: Install HEIF Image Extensions (Recommended)
On Windows 10/11, you can display HEIC files in the standard Photos app by installing 'HEIF Image Extensions' from the Microsoft Store. This is the easiest and most standard method to open HEIC files on Windows.
- 1Open Microsoft Store
Open 'Microsoft Store' from the Start menu in Windows 10/11. Alternatively, search for 'Microsoft Store' in the taskbar search box and open it.
- 2Search for HEIF Extensions
Search for 'HEIF Image Extensions' or 'HEIF Image Extensions' in the Microsoft Store search bar. We also recommend searching for and installing 'HEVC Video Extensions' (HEVC is the video version of HEIF).
- 3Install the Extensions
Select 'HEIF Image Extensions' from the search results and click 'Get' or 'Install'. This extension is provided for free. Installation may take a few minutes.
- 4Restart Your PC (if needed)
After installing the extension, we recommend restarting your PC. After restarting, you should be able to open HEIC files by double-clicking them in the standard Photos app.
- 5Open HEIC Files
Double-click HEIC files in File Explorer, or right-click and select 'Open' to view them in the Photos app. However, this method only allows viewing; separate tools are needed for editing or conversion.
NoteEven after installing this extension, you cannot convert HEIC files to other formats. If conversion is needed, you will need to use dedicated conversion tools. Also, this extension is not available on older versions such as Windows 7 or Windows 8.
Method 2: Use Online HEIC Viewers
If you don't want to install software or just want to temporarily check HEIC files, you can use online viewers.
Using HEIC.Best's free online HEIC viewer, you can display HEIC files directly from your browser. No software installation is required, and files can be viewed instantly by simply uploading them. It also supports displaying EXIF metadata.
Method 3: Convert to JPG or PNG

Using HEIC.Best's free online conversion tool, you can easily convert HEIC files to JPG, PNG, or PDF. After conversion, you can open them on any device without any issues. Batch conversion for multiple files is also available.
How to Open HEIC Files on Mac
On Macs running macOS High Sierra (10.13) or later, HEIC format is natively supported. Therefore, opening HEIC files on Mac is very easy.
The easiest way to open HEIC files on Mac is to double-click the file. It will automatically open in the standard 'Preview' app. In Preview, you can not only view HEIC files but also edit and convert formats.
You can also open and view HEIC files in the Photos app. Photos synchronized to your iCloud Photo Library are also automatically displayed.
On Mac, converting HEIC format to other formats is also easy. Open HEIC files in Preview, select 'File' → 'Export', and simply change the save format to JPEG or PNG to convert.
How to Open HEIC Files on iPhone/iPad
On iPhone and iPad, HEIC format is natively supported, so you usually don't need to do anything. Photos taken with the Camera app are automatically saved in HEIC format and can be viewed as-is.
To open HEIC files in the Photos app, simply launch the app and tap the photo you want to view. You can also open and view HEIC files from the Files app.
If you want to convert HEIC files on iPhone, you can convert them to JPEG format by selecting a photo in the Photos app, tapping the 'Share' button, and selecting 'Format' → 'JPEG' (iOS 13 and later).
When transferring photos from iPhone to PC, HEIC files may be automatically converted to JPEG. This depends on your PC settings and transfer method.

Common Issues and Solutions
Files won't open even after installing HEIF extensions
Try restarting your PC. If that doesn't work, check if the extension is properly installed and reinstall if necessary. We also recommend installing HEVC Video Extensions together.
Microsoft Store won't open
Try repairing or resetting Microsoft Store from Windows Settings. Alternatively, run Windows Update to update your system to the latest state. If it still doesn't work, we recommend using online viewers or conversion tools.
HEIC file appears to be corrupted
If the file is corrupted, it cannot be opened. If the original file is available, try transferring it again. Alternatively, try with another HEIC file to determine if the issue is with the file itself or your system.
Cannot upload to online tools
Check your internet connection. Also, issues may occur if the file size is too large or due to browser cache. Clear your browser cache or try with another browser.
