HEIC vs JPG — Apple Format vs Universal Standard
Understand why your iPhone uses HEIC, how it compares to JPG, and when you need to convert HEIC to JPG for compatibility.
Published May 1, 2026 · By the TryDocsy Team
Why Does My iPhone Use HEIC?
HEIC is Apple's default format because it offers roughly 50% better compression than JPG at the same visual quality. This means your iPhone photos take up half the storage space while looking just as good.
However, HEIC isn't universally supported. Windows PCs, some Android devices, and older software may not open HEIC files directly, which is when conversion to JPG becomes necessary.
Keep HEIC format when:
- 📱 Sharing between Apple devices
- 📱 Saving storage on your iPhone
- 📱 Sending to other iPhone/Mac users
- 📱 Keeping original quality for editing
- 📱 Storing in iCloud Photos
