If you’ve ever moved photos from your iPhone to a Windows computer, you’ve probably run into this issue:the image won’t open, shows an error, or doesn’t preview at all.
That’s because iPhones save photos as HEIC files, a format that Windows doesn’t always handle well.
HEIC is Apple’s image format designed to keep high quality while saving space.It works perfectly on iPhones and Macs, but Windows support is limited and often unreliable.
There are a few common reasons:
Windows doesn’t support HEIC out of the box
required HEIF/HEVC codecs are missing or outdated
many apps and websites don’t accept HEIC files
So even though the image itself is fine, Windows and many programs simply can’t open it.
Instead of installing codecs or dealing with Windows settings, the easiest fix is to convert the image to PNG.
PNG works everywhere:
all Windows versions
all browsers
all image editors and websites
Once converted, the image opens and uploads without any issues.
You should convert HEIC files if you:
use a Windows PC
upload images to websites
send photos to people without Apple devices
edit images in Windows software
PNG avoids compatibility problems completely.
