HEIC photos from an iPhone won't open? How to make them work everywhere
You copy photos from an iPhone to a Windows laptop or upload them to a web form, and suddenly nothing opens. The files end in .heic, and many programs do not know what to do with them.

What HEIC is and why the iPhone uses it
HEIC is Apple's name for images stored in the HEIF container with HEVC compression. Since iOS 11, iPhones use it by default under the setting called High Efficiency. At similar visible quality, a HEIC photo is often about half the size of a JPEG, which saves a lot of storage.
The drawback is support. HEVC is covered by patents, so not every operating system, browser or upload form includes a decoder.
Where HEIC causes problems
Windows can only display HEIC after the HEIF and HEVC extensions from the Microsoft Store are installed, and the HEVC extension may cost a small fee. Many web forms for applications, insurance claims or online shops accept only JPG or PNG. Older photo editors and some Android devices cannot read the format either.
Convert HEIC to JPG
For photos you already have, conversion is the quickest fix. The HEIC converter creates JPG, PNG or WebP copies and leaves the originals untouched.
UseTool deliberately relies on the image decoder of your device instead of shipping its own. Safari on iPhone, iPad and Mac reads HEIC natively. If your browser cannot open the format, the tool says so clearly instead of quietly uploading your photos to a server that can.
- Open the converter in a browser that can display HEIC, for example Safari on the iPhone itself.
- Select the photos. Several at once are fine.
- Choose JPG for maximum compatibility, or PNG if you need lossless output.
- Download the converted copies and use those for the upload or email.
Stop the problem at the source
On the iPhone, open Settings, then Camera, then Formats, and choose Most Compatible. New photos are then saved as JPG. They take more space, but open everywhere.
If you prefer to keep HEIC on the phone, open Settings, then Photos, and set Transfer to Mac or PC to Automatic. Photos copied to a computer by cable are then converted to a compatible format during the transfer.
Sharing through Mail or many messaging apps often converts automatically as well, but not every route does, so a quick check of the file extension before an important upload saves trouble.
Does converting lose quality?
Converting to JPG compresses the picture again, but at a high quality setting the difference is not visible in normal use. Live Photos lose their short video part, because JPG can only store a single image. Keep the HEIC originals if you want to preserve that.
