A detailed comparison of HEIC and JPG image formats. Learn the key differences, pros and cons, and when to convert between them.
The Format Confusion
If you own an iPhone, you've encountered HEIC files. They're the default photo format on iOS — but when you try to share, upload to a website, or open them on Windows, things break.
Let's settle the debate: when should you use HEIC, and when should you convert to JPG?
What is HEIC?
HEIC (High Efficiency Image Container) uses the HEVC video codec to compress still images. Apple adopted it as the default iPhone format in iOS 11 (2017).
- Uses advanced compression from video encoding
- Supports 16-bit color depth (vs JPG's 8-bit)
- Can store image sequences

What is JPG?
JPG (JPEG) has been the universal image standard since 1992. It uses DCT-based lossy compression and is supported everywhere.
- 30+ years of universal adoption
