    Why Windows can't open HEIC files

    Windows 10 and 11 have no built-in HEIC support. Here's why, and the easiest ways to fix it.

    The Windows HEIC problem

    When you transfer iPhone photos to a Windows PC via USB, email, or OneDrive, you end up with .heic files that Windows Photo Viewer and Explorer can't display. You'll see a generic file icon instead of a preview.

    Microsoft offers a fix — the "HEIF Image Extensions" in the Windows Store — but it requires admin rights to install, costs money on some Windows versions, and doesn't help if you're on a work or school computer.

    The browser solution (no install)

    ConvertStack runs entirely in your browser using WebAssembly — a technology built into Chrome, Edge, and Firefox. There's nothing to install, no admin rights needed, and it works on any Windows PC including locked-down corporate machines.

    How to transfer HEIC from iPhone to Windows

    Connect your iPhone via USB

    Use your Lightning or USB-C cable. Trust the computer when prompted on your iPhone.

    Open File Explorer

    Your iPhone appears as a portable device. Navigate to Internal Storage → DCIM → and find your photos.

    Copy HEIC files to your Downloads folder

    Select the photos you want, copy, and paste into a folder on your Windows PC.

    Drag the files into ConvertStack above

    Drop the HEIC files from your folder into the converter. Download the JPGs when done.

    Alternative: Use iCloud for Windows

    If you use iCloud Photos, the iCloud for Windows app can automatically convert HEIC to JPG when you download from iCloud. Go to iCloud settings → Photos → enable "Keep Originals" or choose JPG in the download format option.
