What is HEIC Format?

HEIC (High Efficiency Image Container) is a modern image format developed by the Moving Picture Experts Group (MPEG) and adopted by Apple as the default photo format for iPhone and iPad starting with iOS 11 in 2017.

HEIC vs HEIF: What's the Difference?

HEIF (High Efficiency Image Format) is the technical standard, while HEIC is the file extension used for images stored in the HEIF format. In practice, the terms are often used interchangeably.

Why Did Apple Choose HEIC?

Key Benefits:

  • Better Compression: HEIC files are about 50% smaller than JPG at the same quality
  • Higher Quality: Maintains better image quality at smaller file sizes
  • Advanced Features: Supports transparency, 16-bit color, and multiple images in one file
  • Storage Savings: Users can store twice as many photos in the same space

Technical Advantages of HEIC

Compression

Uses HEVC (H.265) video compression technology, which is significantly more efficient than the JPEG standard from 1992.

Color Depth

Supports 16-bit color compared to JPG's 8-bit, allowing for more accurate color representation and better editing flexibility.

Transparency

Unlike JPG, HEIC supports transparency (alpha channel), similar to PNG, making it versatile for various use cases.

Multiple Images

Can store multiple images in a single file, useful for burst photos, Live Photos, and image sequences.

The Compatibility Problem

Despite its technical advantages, HEIC has one major drawback: limited compatibility.

Compatibility Issues:

  • Windows doesn't support HEIC natively (requires codec installation)
  • Many older Android devices can't open HEIC files
  • Most web browsers don't display HEIC images
  • Many photo editing and sharing platforms don't accept HEIC
  • Older versions of macOS and iOS can't open HEIC files

When to Use HEIC vs JPG

Use HEIC When:

  • Storing photos on your iPhone or iPad
  • Sharing between Apple devices
  • You need to save storage space
  • Working within the Apple ecosystem

Use JPG When:

  • Sharing photos with non-Apple users
  • Uploading to websites or social media
  • Sending photos via email
  • Maximum compatibility is needed

How to Convert HEIC Files

The easiest way to use HEIC files across all platforms is to convert them to more compatible formats like JPG or PNG.

Conversion Options:

HEIC to JPG

Best for photos and general use. Smaller file sizes, universal compatibility.

How to Change iPhone Settings

If you prefer to capture photos in JPG format instead of HEIC:

  1. Open Settings on your iPhone
  2. Scroll down and tap "Camera"
  3. Tap "Formats"
  4. Select "Most Compatible" instead of "High Efficiency"

Note: This will increase the storage space used by photos, as JPG files are larger than HEIC.

The Future of HEIC

While HEIC offers clear technical advantages, widespread adoption has been slow due to licensing costs and compatibility concerns. However, as more devices and platforms add support, HEIC may eventually become as common as JPG. Until then, conversion tools remain essential for ensuring your photos work everywhere.
