If you have ever tried to share a photo from your iPhone and been told the file “isn’t supported,” you have run into HEIC. Since iOS 11, iPhones save photos in the HEIC format by default — it looks great and saves space, but it isn’t as universally compatible as good old JPG. In this guide we’ll show you every reliable way to convert iPhone photos to JPG, whether you’re on an iPhone, Mac, Windows PC, or just want a quick browser-based tool.
Why do iPhone photos save as HEIC?
HEIC (High Efficiency Image Container) is Apple’s implementation of the HEIF standard. It stores images at roughly half the file size of a JPG while keeping similar visual quality, which means more photos fit on your phone. The trade-off is compatibility: many older apps, websites, Windows programs, and third-party services still expect a JPG (also written as JPEG). Converting to JPG makes your photos work everywhere.
Method 1: Make your iPhone shoot JPG from the start
If you’d rather avoid converting altogether, you can tell your iPhone to capture photos in a more compatible format:
- Open Settings and tap Camera.
- Tap Formats.
- Select Most Compatible instead of High Efficiency.
From now on, new photos are saved as JPG. Note that this doesn’t change any of the HEIC photos already in your library — for those, use one of the methods below.
Method 2: Convert existing HEIC photos to JPG
On your iPhone
The simplest trick is to copy the image: open the photo, tap Share, choose Copy Photo, then paste it into an app like Files or Notes — iOS often pastes a JPG copy. Alternatively, emailing a photo to yourself or dropping it into many chat apps will convert it automatically.
On a Mac
Open the HEIC file in Preview, choose File → Export, and pick JPEG from the format menu. In the Photos app you can also select images and use File → Export to save JPG copies in one go.
On Windows
Recent versions of the Windows Photos app can open HEIC (you may need Apple’s free HEIF/HEVC extensions) and let you Save as a JPG. If that feels fiddly, an online tool is usually faster.
The fastest way: an online converter
When you just want it done in seconds, use a free online HEIC converter. Upload your HEIC files, convert them to JPG right in your browser, and download the results — no software to install, and it works on any device including Android phones and Chromebooks. It’s the easiest option when you need to convert a batch of holiday photos quickly.
Bonus: shrink your JPGs to save space
Once your photos are in JPG format, you may want to make them smaller for email, uploads, or a website. After converting, you can Compress JPG files to reduce their size dramatically while keeping them sharp. This is especially handy if you’re sending many images at once or a service has a strict file-size limit.
HEIC vs JPG: which should you keep?
If storage space matters and you mostly stay inside Apple’s ecosystem, HEIC is excellent. If you frequently share photos with Windows users, upload to older websites, or edit in a wide range of apps, JPG is the safer, more universal choice. Many people keep High Efficiency on their iPhone and simply convert to JPG on the occasions they need to share.
Frequently asked questions
Does converting HEIC to JPG reduce quality? There is a small quality loss because JPG is also a compressed format, but for everyday photos the difference is essentially invisible.
Will I lose my HEIC originals? No — every method above creates a new JPG copy and leaves your original HEIC files untouched.
Can I convert many photos at once? Yes. Mac’s Photos export and browser-based converters both handle batch conversions, so you can process an entire album in one step.
That’s everything you need to turn stubborn HEIC files into friendly, shareable JPGs. Whichever method you choose, your iPhone photos will be ready to open anywhere.
