HEIC to JPG — Everything iPhone Users Need to Know

What is HEIC?

HEIC (High Efficiency Image Container) is Apple's implementation of the HEIF standard, developed by the Moving Picture Experts Group (MPEG). Apple introduced HEIC as the default iPhone photo format in iOS 11 (2017). The main advantage of HEIC over JPEG is file size: a HEIC photo is typically 40-50% smaller than an equivalent JPEG while appearing identical to the human eye.

Why Can't Everyone Open HEIC Files?

HEIC is a relatively new format requiring specific codecs to decode. Windows 10 and 11 support HEIC natively only if you install the HEVC Video Extensions from the Microsoft Store. Older Windows versions require third-party software. Android phones, most websites, and non-Apple applications commonly lack HEIC support.

How to Convert HEIC to JPG

Method 1: Online Tool — Easiest, Fastest

Use imgavio's free HEIC to JPG converter. Upload your HEIC files, conversion happens locally in your browser with no server upload, and you download the JPG results. Supports unlimited batch conversion simultaneously.

Method 2: iPhone Settings — Prevent HEIC for Future Photos

Go to Settings > Camera > Formats > select "Most Compatible." This switches to JPEG for all new photos. Note: existing HEIC photos remain as HEIC. When you AirDrop or email photos to non-Apple devices, iOS automatically converts to JPEG if you select "Most Compatible."

Method 3: Mac Preview

Open the HEIC file in Preview, then go to File > Export, and choose JPEG from the format dropdown. Works for individual files. For batch conversion on Mac, use Automator with the Change Type of Images action.

Does Converting HEIC to JPG Lose Quality?

Minimal quality change. Both HEIC and JPEG use perceptual compression with different algorithms. Converting between lossy formats inherently involves some re-encoding. At JPEG quality 90-95, the output is visually identical to the HEIC original for virtually all photos.

Should I Keep HEIC or Switch to JPEG?

Keep HEIC if: Storage space is a priority, you primarily view photos on Apple devices, and you rarely share with Windows users. Switch to JPEG if: You frequently share with non-Apple users, upload to websites or services that don't support HEIC, or use Windows-based photo editing software.

Frequently Asked Questions

Why does Apple use HEIC instead of JPG?

Apple switched to HEIC in iOS 11 (2017) because HEIC achieves roughly 50% better compression than JPEG at the same visual quality — meaning iPhone users can store about twice as many photos in the same storage space. HEIC also supports features JPEG doesn't, including live photos, depth maps, and HDR content.

Does converting HEIC to JPG reduce quality?

Slightly. HEIC is more efficient than JPEG, so converting to JPEG at equivalent visual quality produces a somewhat larger file. However, at JPEG quality 85, the visual difference is imperceptible in almost all cases. The compatibility gain is worth the negligible quality trade-off.

Why can't Windows open HEIC files?

Windows doesn't include HEIC support by default because HEIC is based on HEVC (H.265) video codec technology, which involves patent licensing. You can add HEIC support by installing the free 'HEIF Image Extensions' codec from the Microsoft Store.

How do I stop my iPhone from taking HEIC photos?

Go to Settings → Camera → Formats → select 'Most Compatible' instead of 'High Efficiency.' Your iPhone will shoot JPEG going forward. Alternatively, go to Settings → Camera → Transfer to Mac or PC → Automatic to convert automatically when connecting to a non-Apple computer.

Can I convert HEIC files without uploading them to a server?

Yes. imgavio converts HEIC to JPG entirely in your browser using WebAssembly — your photos never leave your device. This is particularly important for personal photos that contain GPS location data.
