How to Convert iPhone HEIC Photos to JPG
To open iPhone HEIC photos on a PC or in any app, convert them to JPG: upload the .heic file to a browser-based converter, and if your browser can decode it, choose a quality level and download a standard JPEG in seconds. HEIC is what iPhones shoot by default, and while it saves space, it refuses to open on much of the software outside Apple's ecosystem.
This guide covers the conversion, why Windows chokes on HEIC, and how to stop the headache at the source on your phone.
What is HEIC and why won't it open?
HEIC — High Efficiency Image Container — is the format iPhones and iPads use out of the box. It stores photos at roughly half the size of JPEG at the same quality, which is great for your storage but bad for compatibility. Windows doesn't ship with a HEIC decoder, many Android apps can't read it, and older editors ignore it entirely. That is why airdropping or emailing an iPhone photo to a Windows user so often ends in a file that simply won't open. Converting to JPEG makes the photo readable everywhere with no codec juggling.
How to convert HEIC to JPG in your browser
- Upload a .heic or .heif photo straight from your iPhone or iPad.
- The tool tries to decode it using your browser's built-in image support.
- If decoding succeeds, set the JPEG quality and preview the result.
- Click Download to save the JPG — or follow the on-screen tips if your browser can't decode HEIC.
One honest note up front: in-browser HEIC decoding is mostly limited to Safari. If you're on Chrome, Edge or Firefox, the tool detects the failure immediately and points you to a working path instead of leaving you staring at an error.
Fix it at the source: stop shooting HEIC
If you regularly send photos to non-Apple devices, the cleanest fix is changing your camera format so conversion is rarely needed.
| Goal | What to do |
|---|---|
| Shoot JPEG directly | Settings → Camera → Formats → Most Compatible |
| Keep HEIC's space savings | Leave it on High Efficiency; let iPhone auto-convert on share |
| Convert existing HEIC photos | Use this tool in Safari, or on a Mac use Preview's Export |
Choosing Most Compatible costs you a bit of storage but ends the compatibility problem for every new photo you take.

Frequently asked questions
Why won't my HEIC photos open on Windows?
Windows doesn't include a HEIC decoder by default; it needs the HEVC Video Extensions from the Microsoft Store. Converting the photos to JPG avoids the problem entirely because JPEG opens everywhere without extra codecs.
Which browsers can convert HEIC files?
Safari on macOS and iOS decodes HEIC natively, so the tool works perfectly there. Chrome, Edge and Firefox currently can't decode HEIC — if you use one of them, the tool detects it and suggests opening the page in Safari.
How do I stop my iPhone taking HEIC photos?
Open Settings → Camera → Formats and pick Most Compatible; the camera then saves JPEG directly. Or keep HEIC and let the iPhone convert automatically when you share via Mail or over USB to Windows.
Does converting HEIC to JPG lose quality?
Only a tiny amount, since both formats are lossy — at quality 85 or higher the difference is invisible. Expect the JPG to be about twice the file size of the HEIC, because HEIC compresses roughly twice as efficiently.
Is it safe to convert my personal photos here?
Yes. Conversion runs completely inside your browser, so photos are never uploaded, stored or seen by any server — far more private than cloud-based HEIC converters.
