Your iPhone shoots HEIC. The rest of the world wants JPG.
Since iOS 11, iPhones save photos in HEIC by default — great for storage, frustrating for sharing.
The problem
- Windows PCs, older Android phones, and many websites can't open HEIC files.
- Email providers and upload forms reject photos that are too large.
- Web converters make you upload private photos to someone else's server — and make you wait.
- Converting photos one at a time is tedious when you have a whole batch to share.
