1. Use the browser (no install): DoItSwift HEIC to JPG
Upload or drop your .heic files into our HEIC to JPG converter. Conversion happens locally in your
browser when supported; you get standard JPG files you can open anywhere. Best when you want a quick fix without
installing software.
2. Install the HEIF extensions from Microsoft
Microsoft offers optional codecs so the Photos app and File Explorer can show HEIC thumbnails and open files.
Search the Microsoft Store for HEIF Image Extensions and HEVC Video Extensions
(HEIC still images often need the HEIF pack). They are free or low-cost depending on region. After installation,
double-clicking a .heic file may open in Photos.
3. Use the Photos app after codecs, or “Open with” another viewer
Once HEIF support is installed, Photos can often display HEIC files. You can also try other free viewers you trust. If you only need to share images online or with apps that expect JPG, converting to JPG (method 1) remains the most compatible route.
For a full HEIC vs JPG comparison (quality, file size, and when to convert), see that guide next. If you need step-by-step export options from an iPhone, read how to convert iPhone photos to JPG. Once you have JPGs, you can shrink JPG file size in your browser before emailing or uploading to picky portals.
Quick comparison
- Fastest with no install: browser conversion (method 1).
- Best for native Windows preview: Microsoft codecs (method 2).
- Best for archiving iPhone originals: keep HEIC and add codecs, or convert copies to JPG for sharing.
Troubleshooting common HEIC issues on Windows 11
"This file isn't supported" error when opening HEIC
Windows 11 doesn't include HEIC support out of the box. Install the HEIF Image Extensions from the Microsoft Store. If you still see errors after installation, you may also need the HEVC Video Extensions — HEIC photos use HEVC video codec internally, which Microsoft licenses separately.
HEIC thumbnails not showing in File Explorer
Even after installing the HEIF extension, thumbnails sometimes don't refresh. Try these steps:
- Restart File Explorer (Ctrl+Shift+Esc → find "Windows Explorer" → Restart)
- Clear the thumbnail cache (Disk Cleanup → Thumbnails)
- Sign out and back into Windows
Photos app crashes when opening HEIC
A known issue with older HEIF extension versions. Update the extension via the Microsoft Store: Library → Get Updates. If crashes persist, try converting HEIC to JPG instead — most apps that fail on HEIC handle JPG fine.
HEVC Video Extensions costs $0.99 — is there a free version?
Microsoft offers a free HEVC extension specifically for device manufacturers — search the Microsoft Store for "HEVC Video Extensions from Device Manufacturer." Note that Microsoft has changed availability over time; if the free version isn't available in your region, converting HEIC to JPG in a browser avoids the codec issue entirely.
Bulk converting many HEIC files at once
The Microsoft codecs let you view HEIC but don't help with bulk conversion. For converting hundreds of iPhone photos to JPG at once, use a browser-based batch converter — drop the entire folder, get a ZIP of JPGs in seconds. No upload limits or watermarks.
Frequently Asked Questions
Does Windows 11 support HEIC natively in 2026?
Not fully. Windows 11 requires the free Microsoft HEIF Image Extension to display HEIC files. For HEIC photos from iPhone (which use HEVC compression), you also need the HEVC Video Extension, which typically costs about $0.99 from the Microsoft Store. Without these extensions, .heic files show errors when opened.
How do I open HEIC files on Windows 11 without installing anything?
Use a browser-based HEIC to JPG converter. Upload your HEIC file via drag and drop, and download a standard JPG that opens in any Windows 11 app — including Photos, File Explorer, Paint, and any image editor. No installation, no Microsoft Store extensions needed.
Why does Windows 11 not support HEIC by default?
HEIC uses HEVC (H.265) video codec compression internally. HEVC is patented technology requiring licensing fees that Microsoft does not pay for all Windows installations. Apple licenses HEVC for iPhone/Mac users; Microsoft offloads the cost to users through optional Microsoft Store extensions.
Is the HEIF Image Extension safe to install?
Yes — it's published by Microsoft Corporation directly through the official Microsoft Store. It's the same extension Microsoft ships to enterprise customers. Avoid third-party HEIC viewers from unofficial download sites — they often bundle adware.
Can I convert HEIC to JPG on Windows 11 for free?
Yes. The fastest free method is a browser-based converter that runs entirely on your device — no upload, no signup. Drag your HEIC files in, download JPGs out. Works offline once the page loads. Alternative: open HEIC in the Photos app (after installing codecs) and use 'Save As JPEG'.
Does converting HEIC to JPG lose photo quality?
Minor quality loss occurs because JPG uses older compression. At high quality settings (90%+), the difference is invisible for most photos. The bigger consideration is metadata — make sure your converter preserves EXIF data (timestamp, camera settings, GPS location) if those matter to you.
Can I tell Windows 11 to always open HEIC in a specific app?
Yes. Right-click any .heic file → 'Open with' → 'Choose another app' → select your preferred viewer → check 'Always use this app to open .heic files'. After installing the HEIF extension, the Photos app is the natural choice for most users.
Why are my iPhone photos saving as HEIC instead of JPG?
iPhone defaults to HEIC since iOS 11 (2017) to save storage space — HEIC files are roughly 50% smaller than JPG at the same quality. To switch your iPhone to JPG: Settings → Camera → Formats → select 'Most Compatible'. New photos will save as JPG; existing HEIC photos stay HEIC.
