HEIC to JPG: Why Your iPhone Photos Won't Open and How to Fix It
You plug your iPhone into your Windows PC, copy your photos over, and then find that Windows Photo Viewer cannot open them. Or you try to upload a photo to a website and it fails. This is the HEIC problem — and it affects millions of iPhone users every day.
What Is HEIC?
HEIC (High Efficiency Image Container) is Apple's default photo format, introduced with iOS 11 in 2017. It uses the HEVC codec to compress photos roughly twice as efficiently as JPG — meaning photos are about half the size with the same or better visual quality. That is why Apple made it the default: it saves storage on your iPhone.
The problem is that HEIC is an Apple-proprietary format not natively supported by Windows, most Android devices, web browsers (until very recently), or the majority of apps and websites.

How to Stop iPhone From Shooting HEIC
Go to Settings ? Camera ? Formats and select Most Compatible instead of High Efficiency. Your camera will now shoot JPG directly. The trade-off is larger photo file sizes, but you will never have compatibility issues again.
Alternatively, keep shooting HEIC (better quality, smaller size) and only convert to JPG when you need to share photos on Windows or with services that do not support HEIC.

- Quality: HEIC is equal or better quality at smaller sizes
- Compatibility: JPG works everywhere; HEIC works only on Apple and modern systems
- Transparency: HEIC supports transparency; JPG does not
