What Is HEIC and How to Convert It to JPG (Windows, Mac, Web)
HEIC is the efficient photo format iPhones use. Many Windows apps and websites cannot open it, so convert to JPG by dropping your files into a browser converter that works without uploads.
What is HEIC?
HEIC (High Efficiency Image Container) stores photos at about half the size of JPG with similar quality. Apple made it the default camera format on iPhones.
Why HEIC causes problems
Windows needs an extra codec to open HEIC, many websites and forms reject it, and older apps cannot edit it. JPG works everywhere.
Convert HEIC to JPG in your browser
Open the SleekCut HEIC to JPG converter, drop one photo or a whole folder, and download the JPGs one by one or as a ZIP. Conversion happens on your device, so your photos are never uploaded.
Stop saving new photos as HEIC
On iPhone, open Settings, then Camera, then Formats, and choose Most Compatible. New photos will be saved as JPG.
