HEIC vs JPG: Why iPhones Save Photos as HEIC and How to Convert Them Free
Discover why Apple adopted High Efficiency Image Coding (HEIC) and how to convert HEIC to JPG client-side without quality loss.
Since iOS 11, Apple devices capture photographs in the High Efficiency Image Container (HEIC) format. While HEIC delivers superior compression at roughly half the file size of an equivalent JPEG, most web portals and third-party upload systems cannot open or parse HEIC files.
### Why Pixzen's In-Browser Converter is Superior
Traditional online converters upload your personal camera rolls to remote servers where they may sit indefinitely. Pixzen uses client-side JavaScript decoding to convert HEIC to standard JPEG directly on your device CPU/GPU. Your camera roll photos never leave your device.
