iPhones save photos as HEIC — a format many websites, forms, and Windows PCs still refuse. This turns them into JPGs that work everywhere. First time? Add the photo and press Convert. Free, no signup — and the photo never leaves your device.
Why do iPhones use HEIC? It stores the same photo in about half the space of JPG. The trade-off is compatibility: Apple devices handle it natively; much of the rest of the world still asks for JPG.
Can iPhone stop saving HEIC? Yes — Settings → Camera → Formats → “Most Compatible” makes new photos JPG. Existing HEIC photos still need converting, which is what this page is for.
Is any quality lost? A small amount, as with any JPG conversion — invisible in normal use. The original HEIC stays untouched on the device.
