If you own an iPhone, you’ve probably run into a strange file extension you never asked for: HEIC. You take a photo, try to share it with a friend on Windows, upload it to an old website, or open it in an editing tool and suddenly it either won’t open, looks broken, or shows up as a blank thumbnail. The fix, most of the time, is simple: convert it to JPG.
Here’s everything you need to know about HEIC, why JPG is often the better choice for sharing, and the different ways you can convert between the two.
What Is HEIC?
HEIC stands for High Efficiency Image Container, and it’s Apple’s implementation of the HEIF (High Efficiency Image Format) standard. Apple made it the default photo format starting with iOS 11 back in 2017.
The appeal is straightforward: HEIC files store the HEIC to JPG same visual quality as a JPG but at roughly half the file size. That matters a lot when you’re shooting hundreds of photos a day on a phone with limited storage. HEIC also supports some extra features JPG doesn’t handle as well, like better color depth and support for image sequences (useful for Live Photos).
Why Convert HEIC to JPG?
Despite its technical advantages, HEIC isn’t universally supported. JPG (or JPEG), on the other hand, has been the internet’s default image format since the early 1990s and works pretty much everywhere. Common reasons people convert HEIC to JPG include:
- Compatibility Many Windows PCs, older software, and some websites and platforms don’t open HEIC files natively.
- Sharing Emailing or messaging a HEIC file to someone on Android or an older device might result in them getting a file they can’t open.
- Editing tools Some photo editors, design programs, and content management systems only accept JPG or PNG uploads.
- Printing services Many photo printing labs and kiosks still require JPG.
- Archiving JPG’s long track record makes it a safer long-term storage bet for photos you want accessible for years.
How to Convert HEIC to JPG
There are several ways to do this, depending on your device and how many photos you’re converting.
On iPhone (Change the Default Format)
If you want your phone to just stop shooting HEIC altogether:
- Go to Settings → Camera → Formats
- Select “Most Compatible” instead of “High Efficiency”
This makes your iPhone save new photos as JPG automatically, though it will take up more storage.
On iPhone or iPad (Convert Existing Photos)
- Select the HEIC photo(s) in your Photos app
- Tap Share
- Choose “Copy Photo” or share via Mail/Messages, which often auto-converts to JPG depending on the recipient
- Alternatively, use the Files app: duplicate the photo, and many share sheets offer a JPG export option
On a Mac
- Open the photo in Preview
- Go to File → Export
- Choose JPEG from the format dropdown and save
On Windows
Windows 10 and 11 can view HEIC files with the free HEIF Image Extensions from the Microsoft Store, and you can then:
- Open the photo in the Photos app
- Click the three-dot menu → Save As or Edit
- Save a copy, choosing JPG as the format
Using Online Converters
For quick one-off conversions without installing anything, websites let you upload a HEIC file and download a JPG version in seconds. This is handy for a single photo but be mindful of privacy avoid uploading sensitive personal photos to unfamiliar sites, and check that the service deletes files after conversion.
Batch Converting Many Photos
If you need to convert dozens or hundreds of photos at once, dedicated desktop apps or command-line tools (like ImageMagick) can process entire folders in one go, which saves a lot of time compared to converting images individually.
Will You Lose Quality?
Converting HEIC to JPG does involve re-compression, since the two formats use different compression methods. In most cases the difference is negligible to the naked eye, especially for casual sharing, printing at normal sizes, or web use. If you’re a professional working with images that require maximum fidelity, it’s worth keeping an original HEIC (or a RAW file, if available) as a backup before converting.

The Bottom Line
HEIC is a smart, efficient format, but its limited compatibility means JPG is still the safer choice when you’re sending photos outside the Apple ecosystem. Whether you convert one photo through your phone’s share sheet or a whole camera roll with a batch tool, getting from HEIC to JPG is a quick fix that saves you from the headache of “why won’t this photo open?”
