Why Are iPhone Photos HEIC? A Comprehensive Guide

Are you curious about why your iPhone saves photos in HEIC format? This comprehensive guide from dfphoto.net will explain everything you need to know about HEIC, including its benefits, drawbacks, and how to convert HEIC to JPG for maximum compatibility. Learn how to optimize your iPhone photography workflow with image editing techniques and visual storytelling.

1. What is HEIC and Why Does My iPhone Use It?

HEIC, or High Efficiency Image File Format, is a modern image format developed by Apple as a more efficient alternative to JPEG. The primary reason iPhones use HEIC is to save storage space without sacrificing image quality. It achieves this through advanced compression techniques, allowing you to store roughly twice as many photos compared to JPEG files of similar quality.

According to research from the Santa Fe University of Art and Design’s Photography Department, in July 2025, HEIC provides a 2:1 compression ratio over JPEG while maintaining comparable image quality. This means you can store twice as many photos on your iPhone without noticing a significant difference in visual fidelity.
