Why HEIC files won't open on Windows (and how to fix it)

iPhones save photos as HEIC (High Efficiency Image Container) by default. HEIC stores the same quality as JPG at a much smaller size, but it is a relatively new format, and Windows often cannot open it without an extra codec installed.

On older Windows 10 machines and managed office PCs in particular, you will see errors like "This file can't be displayed" or "Unsupported format." The file is not corrupted — Windows just doesn't know how to read it yet.

If you just need to open or use the photo now, converting HEIC to JPG is the most reliable fix. JPG opens on virtually every device and app, so once converted, the compatibility problem disappears entirely.

Our HEIC to JPG converter works by simply dropping the file into your browser. Processing happens locally — your photo is never uploaded to a server — so it is safe to use even for personal photos or work documents. Batch conversion of multiple files is supported too.

If you receive HEIC files regularly and converting every time is a hassle, you can install the "HEIF Image Extensions" from the Microsoft Store. This lets the Windows Photos app open HEIC files directly.

Note that some setups also require the paid "HEVC Video Extensions," and corporate PCs often block Store installs. When you need certainty, converting to JPG remains the safer route.

To stop new photos from being saved as HEIC, go to Settings → Camera → Formats on the iPhone and choose "Most Compatible." Future photos will be saved as JPG.

The trade-off is larger files and faster storage consumption on the phone. Keeping HEIC for storage and converting to JPG only when sharing is usually the better balance.

Emailing a photo from the iPhone often converts it to JPG automatically. Likewise, enabling Settings → Photos → "Automatic" under Transfer to Mac or PC converts files to a compatible format during USB transfer.

Cloud drives and chat apps, however, usually pass the original HEIC through untouched. If the recipient can't open it, a quick browser conversion to JPG solves it.

Converting HEIC to JPG keeps the visible quality essentially the same, but the JPG file will usually be larger than the original HEIC — that is normal, since JPG compresses less efficiently. If size matters, run the result through a JPG compressor afterward.

For important photos you may edit later, keep the original HEIC as your master copy. HEIC preserves more quality per megabyte; use JPG as the distribution copy.

The HEIC problem is purely about compatibility, so converting to JPG always resolves it. Use a browser converter for urgent cases, the Windows extension if you receive HEIC often, or change the iPhone setting to fix it at the source.

Filewisp offers both HEIC to JPG and HEIC to PNG conversion for free, with no installation and fully in-browser processing.
