HEIC vs JPG — What's the difference?

1 min read ·

HEIC and JPG are both photo formats, but they have important differences.

HEIC (High Efficiency Image Container)

  • Developed by: MPEG group, adopted by Apple in 2017
  • Compression: HEVC (H.265) — significantly more efficient than JPEG
  • File size: Roughly 50% smaller than JPG at the same visual quality
  • Features: Supports transparency, 16-bit color depth, image sequences, and depth maps
  • Compatibility: Native on iOS/macOS; limited support on Windows and Android

JPG (JPEG)

  • Developed by: Joint Photographic Experts Group, 1992
  • Compression: DCT-based lossy compression
  • File size: Larger than HEIC at equivalent quality
  • Features: No transparency, 8-bit color, single image only
  • Compatibility: Universal — works everywhere

When to use each

Use case Recommended format
Storing photos on iPhone/iPad HEIC (default, saves space)
Sharing photos on the web JPG (universal compatibility)
Sending to Windows users JPG (HEIC may not open)
Archival with best quality HEIC (better compression, higher color depth)
Email attachments JPG (smaller + universally readable)
