HEIC Image

HEIC is an image format primarily used by Apple devices, offering superior compression and advanced features compared to JPEG. It stores high-quality photos in smaller file sizes.

What is HEIC Image?

HEIC (High Efficiency Image File) is a modern image container format based on the HEIF (High Efficiency Image File Format) standard. Developed by the Moving Picture Experts Group (MPEG), it was widely adopted by Apple in 2017 with iOS 11 for storing photos on iPhones and iPads. HEIC files use HEVC (High Efficiency Video Coding) compression, allowing them to store images with significantly higher quality and transparency support at about half the file size of a comparable JPEG. It can also contain image sequences, depth maps, and live photos.

Advantages

  • Significantly smaller file sizes than JPEG.
  • Retains higher image quality after compression.
  • Supports advanced features like Live Photos and image sequences.
  • Includes transparency (alpha channel) and depth map support.

Limitations

  • Limited native compatibility outside Apple ecosystems (Windows, older Android).
  • Requires conversion for broader sharing and editing.
  • Some older software might not support it.

How to open HEIC Image files

Apple Photos (macOS, iOS, iPadOS) Windows Photos (with HEIF Image Extensions) GIMP (with plugin) Adobe Lightroom Google Photos (online) ConvertX (for conversion)

Common use cases

  • Storing high-quality photos on Apple iPhones and iPads.
  • Capturing Live Photos with motion and sound.
  • Saving burst mode sequences efficiently.
  • Reducing storage space for large photo libraries.

Frequently asked questions

HEIC is a specific image container format that uses the HEIF standard. HEIF is the broader standard, while HEIC specifically refers to still images and image sequences encoded with HEVC.
Yes, with the HEIF Image Extensions from the Microsoft Store, Windows Photos can open HEIC files. Without it, you'll need a third-party viewer or to convert them.
Apple adopted HEIC as its default format in iOS 11 to save storage space on devices while maintaining high image quality due to its superior compression efficiency.
You can use online converters like ConvertX's heic-to-jpg tool, or convert them directly on your Apple device or within certain photo editing software.
Yes, HEIC supports alpha channels, allowing for transparent backgrounds in images, similar to PNG.
