You AirDrop a photo from your iPhone, try to open it on a Windows PC or upload it to an older website, and… nothing happens. The culprit is almost always HEIC — Apple's modern photo format. Here's why it happens and how to fix it in seconds, on any device, plus how to stop it happening again.
What is HEIC, and why does it cause problems?
HEIC (High Efficiency Image Container) is the format iPhones and iPads have used by default since iOS 11. It stores photos at roughly half the size of JPG with the same visual quality — great for your storage, but not every app, website or older device understands it yet. JPG, by contrast, opens literally everywhere, from a decade-old laptop to a printing kiosk.
The quick fix: convert HEIC to JPG
Converting HEIC to JPG makes the photo universally compatible. You give up some of the storage efficiency, but you gain the ability to open, edit and share it anywhere — email, Windows, Android, web uploads, old photo frames, the lot.
Convert on any device (easiest)
- Open the HEIC to JPG converter.
- Drag in one photo or a whole batch.
- Convert and download the JPG versions.
This works the same on iPhone, Android, Mac and Windows because it runs in your browser — and your photos are never uploaded to a server, so personal pictures stay private. There's no app to install and no account to create.
Stop your iPhone from saving HEIC in the first place
If you'd rather avoid converting every time, change the capture format on your iPhone:
- Open Settings → Camera → Formats.
- Choose Most Compatible — your iPhone will now shoot JPG instead of HEIC.
The trade-off is larger photo files, so switch only if compatibility matters more than storage. You can flip it back any time, and existing HEIC photos stay as they are.
Another handy setting: transfer as JPG
There's also a setting under Settings → Photos → Transfer to Mac or PC. Set it to Automatic and your iPhone will convert photos to a compatible format when you copy them over a cable — useful if you mostly move photos to a computer. For everything else (AirDrop, uploads, sharing), converting with the tool above is the most reliable route.
Tip: Converting HEIC to JPG slightly increases file size because JPG is less efficient. If you then need a smaller file for the web or email, run it through the image compressor or resize it afterwards.
Turning HEIC photos into a PDF
Need to submit photos as a document? Convert your HEIC shots to JPG first, then combine them into one file with the JPG to PDF tool — perfect for receipts, IDs or paperwork you photographed with your phone.
Batch converting a whole album
Got dozens of HEIC photos to send to someone on Windows or Android? Drop the entire set in at once, convert, and download them together — no need to do them one by one. This is the fastest way to make a holiday album shareable with friends who aren't on Apple devices.
Why does HEIC even exist?
HEIC isn't just Apple being awkward — it genuinely saves space and supports modern features like Live Photos and wider colour. The problem is purely compatibility: the rest of the world hasn't fully caught up. Converting to JPG is the pragmatic bridge until support is universal, letting you keep the storage benefits on your phone while sharing in a format everyone can open.
Where HEIC trips people up most
A few everyday situations cause the most HEIC headaches — and converting to JPG solves all of them:
- Uploading to a website or job portal that only accepts JPG or PNG.
- Sending photos to someone on Windows or Android who can't open the file you sent.
- Adding pictures to a document in older versions of Word or Google Docs.
- Printing at a kiosk or photo lab whose machines don't recognise HEIC.
- Editing in software that simply refuses to import the format.
In every case the fix is the same: convert the HEIC files to JPG first, then proceed as normal. Keep the originals on your phone if you like the space savings — you only need JPG copies for sharing and uploading, not for everything.
Frequently asked questions
Does converting HEIC to JPG lose quality?
There's a tiny, usually invisible loss because JPG re-compresses the image. For everyday sharing it's not noticeable.
Why won't my iPhone photos open on Windows?
Older Windows versions don't support HEIC. Converting to JPG makes them open anywhere.
Can I convert many HEIC photos at once?
Yes — batch-convert a whole set and download them all together.
Will I lose the photo's date or location data?
Basic image data is preserved during conversion, though some apps strip location metadata for privacy when exporting.
Is HEIC better than JPG?
For storage, yes — smaller files at similar quality. For compatibility, JPG wins because it opens everywhere.
Do I need an app to convert HEIC to JPG?
No — the converter runs in any modern browser on iPhone, Android, Mac or Windows, with no app or account needed.
Can I still keep my original HEIC photos?
Yes. Converting creates new JPG copies and leaves your original HEIC files completely untouched on your device, so you keep the storage savings on your phone while still having shareable JPGs ready whenever you need them.
