HEIC (High Efficiency Image Container) is the default photo format on iPhones running iOS 11 and later. It uses the HEVC (H.265) codec to achieve roughly 50% better compression than JPEG at equivalent quality. This means iPhone photos take up half the storage space. The downside is compatibility: Windows, many web browsers, and older software cannot open HEIC files natively. Most users encounter HEIC when trying to share iPhone photos with non-Apple devices or upload them to websites that only accept JPEG or PNG. The solution is converting HEIC to JPEG or PNG, which tools like ConvertQuick handle instantly in the browser.
