HEIC is the high-efficiency image format Apple uses by default on iPhones and iPads since iOS 11.
Based on the HEIF container and HEVC compression, it stores photos at high quality in about half the size of a JPG.
HEIC is great on Apple devices, but to share with Windows, the web or older apps you should convert it to JPG or PNG.
Advantages
- ✓Excellent compression keeps file sizes small.
- ✓Preserves high image quality, ideal for editing and print.
Drawbacks
- ✕Limited support outside specific apps or platforms.
