Why iPhone photos are HEIC
Since iOS 11 the camera saves High Efficiency Image Container files, usually .heic. They look like JPEG and take about half the space. Windows, some websites and older tools still refuse to open them.
Converting HEIC to JPG gives you a file that almost everything accepts. The conversion does not invent detail the HEIC did not have. It unpacks it into a widely readable JPEG.
A HEIC to JPG converter that stays on the device
The picture is read on your device. Nothing is uploaded, and there is no account or watermark.
The decoder is libheif, running in the page. Safari can sometimes decode HEIC itself. Where it cannot, the same page does it. You do not install an app and you do not make an account.
- Batch: drop a whole roll. Each file downloads, or the set comes as a zip.
- Quality is high by default, so a screenshot or a document photo stays readable.
- Need PNG or WebP instead? Use the image converter after, still on this device.
HEIC, HEIF and what this page will not claim
HEIC is the usual still-image form of HEIF. Live Photos and some bursts are more than one image. This page converts the primary still.
A HEIC that uses an unusual codec can fail. You will see that immediately, and the file is still only on your device.
