Transferred photos from your iPhone to a Windows PC only to find you can't open the ".heic" files? This is a common issue for Windows users, and there are several ways to solve it. This guide covers everything from diagnosing the cause to Windows 11/10 fixes and JPG conversion.
What Is HEIC? Why Windows Can't Open It
HEIC (High Efficiency Image Container) is the default photo format Apple has used on iPhones since 2017. It preserves the same quality as JPEG while cutting file size by roughly 50%, helping save iPhone storage.
The main reason Windows can't open HEIC files is that Windows doesn't natively support the format. However, support varies significantly by Windows version.
| Windows Version | HEIC Support | Action Required |
|---|---|---|
| Windows 11 (22H2+) | Native support | Usually opens out of the box |
| Windows 11 (early versions) | Partial | Install extensions |
| Windows 10 | Not supported | Install extensions |
| Windows 8.1 or earlier | Not supported | Convert to JPG |
Method 1: Install HEIF Extensions (Windows 10/11)
On Windows 10/11, installing two free extensions from the Microsoft Store enables native HEIC support.
Required Extensions
You need both extensions — installing only one may not work.
| Extension | Cost | Purpose |
|---|---|---|
| HEIF Image Extensions | Free | Read/write HEIF/HEIC images |
| HEVC Video Extensions from Device Manufacturer | Free | HEVC codec (also used for image decoding) |
Installation Steps
- Open Microsoft Store from the Start menu
- Search for "HEIF Image Extensions"
- Click "Get" to install
- Then search for "HEVC Video Extensions from Device Manufacturer" and install
- Restart your PC
What You Get After Installation
- HEIC file thumbnails appear in File Explorer
- The Photos app opens HEIC files directly
- Paint and other built-in apps can edit HEIC files
Reset If It Doesn't Work
If HEIC files still won't open after installing the extensions:
- Go to "Settings" → "Apps" → "Installed apps"
- Find "HEIF Image Extensions" and click "Advanced options"
- Click "Reset"
- Restart your PC
Method 2: Convert to JPG (Most Reliable)
If you can't install extensions or need to share photos with others, converting HEIC to JPG is the most reliable solution.

Method 3: Change iPhone Transfer Settings
Changing a setting on your iPhone makes it automatically convert photos to JPG when transferring to Windows. This is a root-cause fix for future transfers.
Auto-Convert on Transfer (Recommended)
- Open iPhone Settings → Photos
- Scroll to the Transfer to Mac or PC section
- Select "Automatic"
With this setting, photos are auto-converted to JPG when transferred via USB or AirDrop. Photos on your iPhone stay in HEIC, so there's no impact on storage.
Save as JPG from the Start
To stop creating HEIC files altogether:
- Go to "Settings" → "Camera" → "Formats"
- Select "Most Compatible"
Method 4: Use Cloud Services
If you already use a cloud service, you may be able to get JPGs without any extra tools.
| Service | Download Format | Auto-Convert |
|---|---|---|
| Google Photos | Auto-converts to JPG | Yes |
| iCloud for Windows | JPG option available | Configurable |
| OneDrive | Downloads as HEIC | No |
| Dropbox | Downloads as HEIC | No |
If you use Google Photos, simply downloading from the browser gives you JPG files — no extra steps needed.
Method 5: Use Third-Party Viewers
On corporate PCs where Microsoft Store access is blocked, installing a third-party HEIC-compatible viewer is another option.
- CopyTrans HEIC for Windows: Adds HEIC thumbnail support to File Explorer and right-click JPG conversion (free)
- FastStone Image Viewer: Feature-rich viewer with HEIC support and batch conversion (free for personal use)
- IrfanView: Lightweight viewer with HEIC support via plugin (free for personal use)
Common Troubleshooting
| Issue | Cause | Fix |
|---|---|---|
| Thumbnails don't appear after installing extensions | Cache issue | Restart PC or reset HEIF extension |
| Some apps still can't open HEIC | App doesn't support HEIC | Convert to JPG first |
| Can't install HEIC extensions | Microsoft Store restrictions (corporate PC) | Use a browser-based converter |
| Converted image looks low quality | JPEG quality set too low | Set quality to 85% or higher |
| HEIC file is corrupted and won't open | Data corruption during transfer | Re-transfer from iPhone |
Frequently Asked Questions (FAQ)
Can I open HEIC files directly on Windows 11?
Windows 11 22H2 and later typically opens HEIC without extra steps. On earlier Windows 11 versions or with certain apps, you may need to install "HEIF Image Extensions" and the free "HEVC Video Extensions from Device Manufacturer" from the Microsoft Store.
Do I need both HEIF Image Extensions and HEVC Video Extensions?
Yes. HEIF Image Extensions handles the HEIF/HEIC format, and HEVC Video Extensions provides the HEVC codec used for decoding. Installing only one may not work correctly.
How can I batch convert many HEIC files?
sakutto's HEIC converter supports multi-file batch conversion. Drag and drop all files at once and download the converted results as a ZIP.
Is Exif data (date taken, etc.) preserved after conversion?
Yes. Exif data including the date taken, camera settings, and GPS coordinates is carried over to the converted JPG file.
My company PC can't install software. How do I open HEIC files?
Use a browser-based converter like sakutto's HEIC tool. It runs in any browser with no installation, and files never leave your device — making it secure for corporate environments.
What is the difference between HEIC and HEIF?
HEIF (High Efficiency Image File Format) is the format specification, while HEIC is the file extension for images using HEVC compression. iPhone photos are saved as .heic files, which are technically a type of HEIF.
Summary
To open HEIC on Windows: Windows 11 22H2+ works out of the box; Windows 10 needs extension installation; and when that isn't possible, converting to JPG is the most reliable option.
For corporate PCs where you can't install software, a browser-based converter that never uploads your files is the safest and easiest choice.
