Why can't my computer open this HEIC file?
HEIC (High Efficiency Image Container) is the default photo format on iPhones since iOS 11 — it stores photos at roughly half the size of JPG. The trade-off is compatibility. It still fails, or needs an extra download/plugin, in:
- Windows photo viewers and many older apps (without paid HEVC extensions)
- Email clients — recipients see a grey box or a file they can't preview
- Website upload forms, printers, older photo kiosks, some CMS platforms
- Anything that expects "a normal JPG"
JPG opens everywhere. That's the whole reason to convert.
How to convert HEIC to JPG here (free)
- Open the free HEIC → JPG converter.
- Drop in your .HEIC files — straight from the iPhone, no rename needed.
- Download the .jpg files. Orientation comes out right automatically, with no extra rotation step.
The HEIC decoder (libheif, compiled to WebAssembly) is embedded in the page itself, so conversion happens on your machine. Works with Wi-Fi off, nothing uploaded.
What changes during conversion — and what doesn't
- Format: HEIC → JPG. Your photos become files that open everywhere.
- Metadata: the output JPG carries no EXIF — camera, GPS and timestamp don't carry over. That's usually what you want for anything you share. (See the guide to removing EXIF metadata for why.)
- Size: JPGs are bigger than HEICs — that's the compatibility trade-off, not a bug.
The alternatives, honestly
- iPhone setting "Most Compatible": makes future photos JPG — but bigger, and it does nothing about the HEICs already in your camera roll.
- macOS Preview / Quick Actions: works, one file at a time, on a Mac.
- Windows HEVC extensions: paid add-on, and you're still opening HEICs in apps that barely support them.
- Online converters: your private photos get uploaded to someone else's server. This page does the same job without that.
