HEIC / HEIF

Apple's space-saving photo format that stores images at half the file size of JPEG with equivalent quality.

What is HEIC / HEIF?

HEIC format is Apple's default photo format since iOS 11 that stores images at approximately half the file size of JPEG while maintaining equivalent visual quality. HEIC uses the HEVC video codec to achieve superior compression efficiency compared to traditional JPEG compression. While excellent for iPhone storage, HEIC has limited compatibility outside Apple's ecosystem and typically requires conversion to JPEG or WebP for web use.

Importance of HEIC / HEIF

HEIC compatibility issues can prevent you from sharing photos with non-Apple users or uploading images to web platforms that don't support the format. Converting HEIC to JPEG ensures universal compatibility across all devices, email systems, and social media platforms while maintaining acceptable image quality for web delivery.

HEIC / HEIF in Practice

When you take a photo on iPhone, it saves as HEIC at roughly 1.5MB for a 12-megapixel image, compared to 3MB for the same photo in JPEG format. However, uploading that HEIC file to most websites, emailing to Android users, or opening on Windows computers will fail without conversion. Converting the HEIC to JPEG creates a universally compatible 2.8MB file suitable for any platform.

HEIC / HEIF Best Practices

  • → Convert HEIC files to JPEG before sharing with non-Apple users or uploading to websites.
  • → Maintain HEIC format for iPhone storage to save device space while keeping conversion copies for sharing.
  • → Choose JPEG output when you know photos will be shared across different platforms or devices.

Example of HEIC / HEIF

A photographer takes 100 photos during an event on iPhone, generating 150MB of HEIC files versus 300MB if shot in JPEG. When delivering photos to clients using various devices, they convert the HEIC files to JPEG format, creating 280MB of universally compatible images that open reliably on any device or platform.

Frequently Asked Questions

What is HEIC format?

HEIC format is Apple's High Efficiency Image Container format that became the default photo format for iPhones starting with iOS 11. It uses advanced HEVC compression to store photos at roughly half the file size of JPEG while maintaining the same visual quality. HEIC files save significant storage space on Apple devices but have limited compatibility with non-Apple platforms.

HEIC vs JPEG which is better?

HEIC is better for storage efficiency, offering equivalent image quality at half the file size of JPEG. However, JPEG is better for compatibility, working universally across all devices, platforms, and applications. HEIC is ideal for iPhone storage, while JPEG remains the standard for sharing, web use, and cross-platform compatibility.

Why can't I open HEIC files on my computer?

HEIC files require specific codec support that isn't included in most Windows versions or older software applications. Most web browsers, image editors, and non-Apple devices don't natively support HEIC format. Converting HEIC files to JPEG or installing HEVC codec extensions resolves compatibility issues across different platforms.
