What is HEIC and Why Does Your iPhone Use It?
HEIC (High Efficiency Image Container) is Apple's default photo format since iOS 11 (2017). It uses the HEIF standard with HEVC compression to produce files that are 50% smaller than JPG at the same quality. This means your iPhone can store twice as many photos. The downside: HEIC files don't work everywhere. Windows PCs, many Android devices, older software, and most websites can't open them natively.
Method 1: Free Online Converter (Fastest)
The easiest way on any device — no software to install:
1. Open QuickImageHub HEIC to JPG in any browser
2. Drag and drop your HEIC files (up to 50 at once)
3. Set quality (95% default — visually identical to original)
4. Click Convert → download JPG files (ZIP for multiple)
Privacy: your photos never leave your device
Unlike other converters that upload your photos to a server, QuickImageHub converts everything in your browser using WebAssembly. No upload, no server access.
Method 2: Windows — HEIF Image Extensions
Windows 10/11 can open HEIC files natively after installing a free extension:
1. Open Microsoft Store
2. Search "HEIF Image Extensions"
3. Install (free)
4. HEIC files now open in Photos, File Explorer shows thumbnails
Limitation: This lets you view HEIC files, but doesn't convert them. To get JPG files for sharing, you still need a converter.
Method 3: Mac — Built-in Preview
Mac supports HEIC natively. To convert to JPG:
1. Open the HEIC file in Preview
2. File → Export
3. Change format to JPEG
4. Save
Limitation: One file at a time. For batch conversion, use the online converter (50 files at once).
Method 4: iPhone — Change Default Format
To stop your iPhone from saving as HEIC in the first place:
Settings → Camera → Formats → Most Compatible
This switches to JPG. Trade-off: photos will use ~2× more storage. If storage is tight, keep HEIC and convert only when you need to share.
Alternatively: iPhone automatically converts HEIC to JPG when sharing via email or AirDrop to non-Apple devices. But this doesn't always work (especially when transferring via USB cable to Windows).
