If you’ve ever tried sharing iPhone photos with a Windows computer, website, or older app, you may have run into the mysterious HEIC format. While HEIC helps save storage space and maintain excellent image quality, it isn’t always compatible with every device or platform.
The good news? Changing HEIC to JPG on your iPhone is quick and easy. With just a few settings changes, you can make your photos automatically save as JPG files and convert existing HEIC images whenever needed.
What Is HEIC?
HEIC (High Efficiency Image Container) is Apple’s modern photo format introduced to:
- Save storage space
- Keep image quality high
- Improve photo compression
Compared to JPG:
- HEIC files are usually smaller
- JPG files are more universally compatible
Think of HEIC as a compact suitcase—it holds the same things but takes up less room.
Why Convert HEIC to JPG?
You may want JPG files because:
- Some websites don’t accept HEIC uploads
- Older Windows PCs may struggle to open them
- Certain editing software works better with JPG
- JPG is easier to share across devices
