What Is a HEIC File? (And How to Open It on Windows)
HEIC is the default photo format on iPhones. It's efficient but not universally supported. Here's how to convert it to JPG.
If you have ever transferred photos from an iPhone to a Windows PC and found files ending in .heic, you are not alone. Many people encounter HEIC files for the first time and wonder why they can not open them. In this guide, we explain what HEIC is, why Apple uses it, and how to convert HEIC files to JPG so they work everywhere.
What Is HEIC?
HEIC stands for High Efficiency Image Container. It is a file format developed by the Moving Picture Experts Group (MPEG) and adopted by Apple in 2017, starting with iOS 11. HEIC uses the HEVC (H.265) video codec to compress images, resulting in files that are roughly 50% smaller than equivalent JPEG files — with the same or better visual quality.
This is why Apple chose HEIC as the default photo format for iPhones: it lets you store twice as many photos in the same amount of storage space.
Why Can't Windows Open HEIC Files?
The problem is that HEIC is not a universal standard — it is proprietary technology that requires a license. Windows does not include HEIC support by default, which is why you see errors when trying to open these files. You can install a codec extension from the Microsoft Store to add HEIC support, but the easier solution is to simply convert your HEIC files to JPG.
HEIC vs JPG: What Is the Difference?
- File size: HEIC files are about 50% smaller than equivalent JPG files.
- Quality: HEIC offers better quality at smaller file sizes due to more advanced compression.
- Compatibility: JPG is supported by virtually every device, software, and website on the planet. HEIC is not.
- Editing: JPG is widely supported in photo editors, websites, and social media. HEIC has limited support.
