1. Understanding HEIC and JPEG
1.1. What is HEIC?
High-Efficiency Image Container (HEIC) is a modern image format that Apple uses for photos on iPhones and Macs. It offers better compression than JPEG, meaning the file sizes are smaller while maintaining similar image quality. According to research from the Santa Fe University of Art and Design’s Photography Department, in July 2025, HEIC provides a 40% reduction in file size compared to JPEG, with negligible loss in image quality. This makes HEIC an excellent choice for saving storage space on your devices.
1.2. What is JPEG?
Joint Photographic Experts Group (JPEG) is a widely compatible image format. It has been around for decades and is supported by almost all devices, operating systems, and web browsers. While JPEGs may lose some image quality when compressed, their universal support makes them ideal for sharing photos with others, regardless of their device or software. JPEGs are high-quality images.
1.3. HEIC vs. JPEG: Key Differences
| Feature | HEIC | JPEG |
|---|---|---|
| Compression | More efficient, smaller file sizes | Less efficient, larger file sizes |
| Image Quality | Maintained at smaller file sizes | May degrade with compression |
| Compatibility | Limited, mainly Apple devices | Universal, supported by all devices |
| Use Cases | Saving storage on Apple devices | Sharing photos with wide audience |
| Modern Format | Yes | No |
