What to Do When HEIC Images Won't Open on Windows

Published: Oct 19, 2026 | Updated: Oct 19, 2026 | About (Japanese)

Key points
  • Windows may not open HEIC by default
  • Converting to JPG lets any PC open it
  • You can also make iPhone shoot JPG

After moving iPhone photos to a PC they won't open or show previews. The HEIC format is the cause.

Solution 1: convert to JPG (recommended)

  1. In your phone's browser, open "Convert HEIC to JPG".
  2. Choose photos, convert to JPG and save.
  3. Send them to your PC.

Solution 2: make iPhone shoot JPG

Under Settings → Camera → Formats, choose "Most Compatible" so future shots are JPG. (Photos already taken need converting.)

Solution 3: iPhone transfer setting

Under Settings → Photos → "Transfer to Mac or PC", choose "Automatic" so photos may be converted to a compatible format when transferred to a PC.

Extra note

You can also add Windows' HEIF extension to open them, but that may involve effort or cost depending on your setup.
