What is HEIC? How to Open & Convert Apple HEIC Photos
Published March 6, 2026 · 6 min read
If you've ever tried to share an iPhone photo on a Windows computer or upload one to a website that doesn't accept it, you've encountered the HEIC problem. Here's everything you need to know.
What is HEIC?
HEIC stands for High Efficiency Image Coding. It's a file format based on the HEVC (H.265) video codec, adopted by Apple as the default camera format starting with iOS 11 in 2017. HEIF (High Efficiency Image Format) is the broader standard — HEIC is Apple's specific implementation.
Why Does Apple Use HEIC?
One word: space. HEIC files are approximately 50% smaller than equivalent JPEGs while maintaining the same or better image quality. For a phone that takes thousands of photos, that adds up to gigabytes of saved storage. HEIC also supports:
- 16-bit color depth (vs. JPEG's 8-bit)
- HDR imagery with wide color gamut
- Depth maps from Portrait mode
- Burst photos stored in a single file
- Non-destructive edits baked into the file
The Compatibility Problem
Despite its technical advantages, HEIC struggles with universal adoption:
- Windows: Requires installing the free "HEIF Image Extensions" from the Microsoft Store (plus a paid HEVC codec for video)
- Android: Most modern Android phones can open HEIC, but many apps still can't
- Web: Chrome 85+ and Safari support HEIC, but Firefox still doesn't
- Social media: Some platforms silently convert HEIC to JPEG, others reject it entirely
How to Convert HEIC to JPG
The simplest and fastest approach: use Xonvert's HEIC to JPG converter. It runs entirely in your browser — no upload to any server, no software to install, no file size limits.
Other options include:
- iPhone settings: Go to Settings → Camera → Formats → Most Compatible. This makes your camera shoot JPEG instead of HEIC going forward (but doesn't convert existing photos).
- iPhone sharing: When you AirDrop or email photos from an iPhone to a non-Apple device, iOS automatically converts to JPEG. This only works for sharing, not for files already on your computer.
- macOS Preview: Open the HEIC file, then File → Export and choose JPEG.
Should You Keep Shooting HEIC?
If you primarily use Apple devices and value storage space, yes — HEIC is technically superior to JPEG in every measurable way. If you frequently share photos with non-Apple users or upload to platforms with limited format support, switching your iPhone to "Most Compatible" mode avoids daily friction.
The best middle ground: shoot in HEIC for storage efficiency, and convert to JPG only when you need to share outside the Apple ecosystem.
