Drop iPhone HEIC photos. Each is turned upright, written as JPEG at matched quality, and saved without its GPS location. HEIC opens here in browsers that read it themselves — Safari on Mac, iPhone and iPad.
Which browsers can open HEIC here
This site converts only with what your browser can do itself, and never sends a photo anywhere to be decoded. Safari on a Mac, iPhone or iPad reads HEIC natively, so HEIC to JPG works there in full. Chrome, Edge and Firefox on Windows, Android and Linux do not read HEIC, and on those browsers the file is listed with that reason instead of a broken result.
If you are on one of those browsers, two things work: on the iPhone, Settings › Camera › Formats › Most Compatible makes the camera save JPG from now on; and opening this page in Safari on the iPhone converts the photos already taken.
What the JPG keeps and drops
The photo is turned upright using the orientation the camera recorded, so it no longer depends on the viewer reading that tag. The GPS position, camera details and other metadata are not written into the JPG. Colour is converted to sRGB, which every portal and app displays the same way.
Government and exam portals accept JPEG only, usually within a KB range. For that, use the form mode, which takes a HEIC on the same browsers and lands the JPEG inside the range.
