You take a photo on your iPhone, send it to a friend, and they reply: "it won't open." The culprit is a file format called HEIC — and it trips up millions of people. Here's what it is and how to get a normal JPG everyone can open.
What is HEIC?
HEIC (High Efficiency Image Container) is the format iPhones have used by default since iOS 11. It's based on the modern HEIF standard and it's genuinely clever: it stores photos at roughly half the file size of JPG at the same quality. That saves space on your phone and in iCloud.
The catch: HEIC isn't universally supported. Windows, many Android phones, older software and lots of websites either can't open it or need an add-on. So a format that's great on your iPhone becomes a headache the moment you share it.
Three ways to get a JPG
1. Change your iPhone's camera setting (best long-term fix)
Open Settings → Camera → Formats and choose "Most Compatible." From then on your iPhone shoots JPG instead of HEIC. You lose the space savings, but everything you share just works.
2. Let AirDrop/sharing convert it
When you share HEIC photos to some apps or email, iOS sometimes converts them to JPG automatically — but not always, which is why you can't rely on it.
3. Convert the files you already have
For photos already saved as HEIC, convert them directly. Our free HEIC to JPG converter turns them into standard JPGs in your browser — no app to install, and your photos aren't kept on a server.
Should you keep shooting HEIC?
If your world is mostly Apple devices, HEIC is great — smaller files, same quality. If you frequently share with Windows or Android users, switching to "Most Compatible" saves you the repeated hassle. Either way, converting the odd file when needed takes seconds.
