What does HEIC stand for?

HEIC stands for High Efficiency Image Container. It is the file extension Apple uses for images stored in the HEIF (High Efficiency Image File Format) container using HEVC compression.

Why does my iPhone save photos as HEIC?

Apple adopted HEIC in iOS 11 (2017) to save storage space on devices. A HEIC photo takes about half the storage of an equivalent-quality JPEG, allowing iPhones to store twice as many photos in the same space.

Is HEIC better quality than JPG?

HEIC achieves the same visual quality as JPEG at roughly 50% smaller file sizes. At the same file size, HEIC is noticeably sharper. The tradeoff is compatibility — JPG is supported universally.

What is the difference between HEIC and HEIF?

HEIF (High Efficiency Image File Format) is the container format specification. HEIC is Apple's specific file extension for HEIF images using HEVC compression. They are functionally the same for conversion purposes.

What devices produce HEIC files?

iPhones running iOS 11+ (iPhone 7 and later), iPads running iPadOS 11+, and some Android devices (Samsung Galaxy S8+ on Android 9+) produce HEIC/HEIF files.

How do I open a HEIC file on Windows without paying?

Use FixTools to convert HEIC to JPG in your browser — free, no payment. Alternatively, look for the free OEM version of the HEVC codec in the Microsoft Store (available for some PCs).

Can I permanently change my iPhone to save photos as JPG instead of HEIC?

Yes. Go to Settings > Camera > Formats and select "Most Compatible". Your iPhone will save new photos as JPEG. Existing HEIC photos remain as HEIC and need to be converted individually.

What Is HEIC Format and How to Open It

HEIC (High Efficiency Image Container) is the file format used by iPhones and iPads to store photos since iOS 11 (2017). It is based on the HEIF (High Efficiency Image File Format) standard and uses HEVC compression — the same technology behind modern video streaming — to produce photos that are up to 50% smaller than JPEG while maintaining the same or better visual quality. Despite its efficiency advantages, HEIC has limited compatibility outside Apple's ecosystem, which is why many users need to convert HEIC to JPG.
