File Size & Compression

HEIC Compression

HEIC uses HEVC (H.265) video compression technology adapted for still images, achieving approximately 50% smaller file sizes than JPG while maintaining or improving image quality. This makes HEIC ideal for storing large photo libraries on iPhones and iPads.

  • Up to 50% smaller than equivalent JPG files
  • Based on HEVC (H.265) compression
  • Better quality at same file size as JPG
  • Supports 16-bit color depth
  • Saves significant iPhone storage space
Storage Saver: HEIC's 50% size reduction means you can store twice as many photos in the same space on your iPhone.

JPG Compression

JPG uses traditional DCT-based compression that's been the standard for digital photos for over 30 years. While less efficient than HEIC, JPG's compression is proven, predictable, and universally compatible with all devices and platforms.

  • Standard baseline for comparison
  • Mature, well-understood compression
  • Larger file sizes than HEIC
  • 8-bit color depth standard
  • Reliable across all platforms
Compatibility: JPG's universal support makes it the safest choice for sharing photos across different devices and platforms.

Quality & Visual Fidelity

HEIC Quality Characteristics

HEIC delivers superior image quality with better detail preservation, reduced compression artifacts, and support for wider color gamuts. It's optimized for modern smartphone cameras and displays, capturing more detail in both highlights and shadows.

  • Color Depth: Up to 16-bit per channel
  • Color Space: Wide color gamut support (P3)
  • Quality: Better than JPG at smaller file sizes
  • Artifacts: Fewer compression artifacts
  • Detail: Excellent fine detail preservation
  • HDR Support: Can store HDR image data

JPG Quality Characteristics

JPG provides reliable, proven image quality that's been the standard for digital photography for decades. While not as advanced as HEIC, JPG quality is sufficient for most viewing scenarios and is optimized for the sRGB color space.

  • Color Depth: 8-bit per channel (24-bit RGB)
  • Color Space: sRGB standard
  • Quality: Good, industry standard
  • Artifacts: Visible at high compression
  • Detail: Good for most applications
  • HDR Support: Limited (no native support)

Compatibility & Support

HEIC Compatibility

HEIC has growing support but remains primarily focused on Apple's ecosystem. While newer versions of Windows and Android offer some support, compatibility is not yet universal, often requiring conversion to JPG for sharing.

  • Native support on iOS 11+ and macOS High Sierra+
  • Windows 10 (version 1803+) with codec extension
  • Limited Android support (varies by device)
  • Many web services don't accept HEIC uploads
  • Social media platforms often require JPG
  • Photo printing services may not support HEIC

Frequently Asked Questions

Since iOS 11, iPhones default to HEIC format because it saves approximately 50% storage space compared to JPG while maintaining better image quality. This allows you to store more photos on your device and in iCloud. Your iPhone automatically converts HEIC to JPG when sharing with non-Apple devices.

Yes, but Windows 10 (version 1803+) and Windows 11 require the free HEIF Image Extensions from the Microsoft Store to view HEIC files. Alternatively, you can convert HEIC files to JPG for guaranteed compatibility with all Windows applications and versions.

Go to Settings > Camera > Formats, and select "Most Compatible" instead of "High Efficiency." This will save photos as JPG instead of HEIC. However, you'll lose the storage-saving benefits of HEIC. Note that photos will take approximately twice as much storage space.

Converting HEIC to JPG may result in slight quality loss since both are lossy formats, but when done properly with high-quality settings, the difference is usually imperceptible. The more significant change is the file size increase - JPG files will be approximately twice as large as the original HEIC files.

Android support for HEIC is limited and varies by device and Android version. Some newer Android phones can view HEIC files natively, but many cannot. For reliable sharing between iPhone and Android, it's best to convert HEIC photos to JPG format first.

Keep photos in HEIC if you work exclusively within the Apple ecosystem and value storage savings. Convert to JPG when you need to share photos, upload to websites, print professionally, or work with non-Apple devices. Many users keep HEIC on their iPhone for storage efficiency and convert to JPG as needed for sharing.
