What Is HEIC? And Why Won't My iPhone Photos Open on My PC?
You take a beautiful photo with your iPhone. Later, you email it to yourself, copy it to your Windows computer, or send it to a friend.
Then...nothing.
The photo won't open. Or your computer asks what program you want to use. Maybe the website you're uploading it to says the file type isn't supported.
If this has happened to you, you're not alone.
The problem/issue is usually something called HEIC.
So, what is HEIC?
HEIC stands for High Efficiency Image Container. Apple started saving photos in this format beginning in 2017 because it uses much less storage space than a traditional JPEG while maintaining excellent image quality.
That's great news for your iPhone. You can store thousands more photos without filling up your device as quickly.
The problem starts when those photos leave the Apple (ecosystem) world.
While support for HEIC has improved over the years, many Windows computers, older photo programs, printing services, and websites still prefer—or even require—JPEG files. That's when people suddenly discover that their photos don't behave the way they expect.
Why does this matter?
When you're trying to organize and preserve your family photos, file formats matter more than most people realize.
I've worked with many clients who have thousands of iPhone photos and didn't even know they were using HEIC until something stopped working.
You might run into problems like:
Photos that won't open on an older Windows computer
Difficulty sharing pictures with family members who don't use Apple devices
Printing services that only accept JPEG files
Spending hours converting thousands of photos later because no one knew they were in a different format
None of these problems are difficult to solve—but they're much easier to prevent than fix.
Should you switch to JPEG?
For most people, my answer is yes.
If your primary goal is preserving, organizing, sharing, and enjoying your family photos, JPEG is still the most compatible format available. It has been around for decades, works almost everywhere, and is unlikely to disappear anytime soon.
To change your iPhone camera to save future photos as JPEG:
Settings → Camera → Formats → Most Compatible
NOTE: Your jpg photos will take up a little more storage space, but they'll be much easier to use on virtually any computer, printer, website, or photo organizing software.
What if you already have thousands of HEIC photos?
Don't panic.
You don't need to convert them one at a time. There are several excellent tools that can convert HEIC files to JPG in batches, making the process much faster and easier.
If your photo library is already well organized, the conversion can often be done without disrupting your organization.
Will you lose quality?
This is probably the question I hear most often.
For everyday family photos, the answer is you probably won't notice any difference.
Unless you're a professional photographer doing extensive editing, JPEG provides excellent image quality. More importantly, it's a format that works almost everywhere, making it much easier to preserve and share your memories for years to come.
The Bottom Line
Technology changes quickly. Unfortunately, the explanations don't always keep up.
HEIC is not a bad format—it simply isn't the best choice if your goal is long-term compatibility with all the devices and software your family may use over the years.
Remember, every photo tells a story. The best photo format is the one that lets you easily find it, share it, print it, and enjoy it.
If you're wondering whether HEIC is affecting your photo collection—or you'd like help converting your files and organizing your digital photo library—I'd be happy to help.
