What is a HEIC file?
HEIC is the file extension Apple uses for photos stored in the HEIF container with HEVC (H.265) compression. iPhones and iPads have shot in HEIC by default since iOS 11 in 2017. Compared with JPG at the same visual quality, a HEIC photo takes roughly half the space and can hold 16-bit colour, transparency, depth maps, edits and several images, such as a Live Photo or a burst, in one file.
The catch is licensing: HEVC decoders are patent-encumbered, so Windows needs a paid extension, many web upload forms and older programs refuse the format, and Android support varies by phone. That gap is why HEIC to JPG is one of the most common conversions people run.
When HEIC is the right choice
Strengths
- About half the size of JPG for the same quality
- Wider colour depth, transparency and multiple images per file
- Default on iPhone, so photos need no extra step on Apple devices
Limitations
- Windows, many websites and older software need conversion or plug-ins
- Patent-encumbered codec limits support in open-source tools
- Sharing outside the Apple ecosystem usually means converting anyway
How to open a HEIC file
macOS and iOS open HEIC natively; Windows 10 and 11 need the HEVC Video Extensions from the Microsoft Store. For everything else, convert once: HEIC to JPG for photos to share or upload, HEIC to PNG when a lossless copy matters.
How to convert a HEIC file
HEIC to JPG is the everyday choice for e-mail, forms and Windows; HEIC to PNG keeps every pixel for editing or print. Both keep the photo's orientation and colour profile; check the remaining metadata afterwards with the EXIF viewer.
