You take a beautiful photo on your iPhone, send it to your Windows PC or upload it to a website, and... "File not supported." Or you see a blank icon with the file extension .heic. What is this file, and why isn't it a JPG?
HEIC stands for High-Efficiency Image Format. Starting with iOS 11, Apple made this the default format for taking photos on iPhones and iPads. Why? Because it's better than JPG in almost every way.
It's a superior format. But it has one major problem: compatibility. Most of the world, including many web browsers, Windows applications, and online forms, still expects the universal JPG format.
| Feature | HEIC (iPhone) | JPG (Universal) |
|---|---|---|
| File Size | Very Small (High Efficiency) | Larger (Standard) |
| Quality | Excellent (16-bit color) | Good (8-bit color) |
| Compatibility | ❌ Low (Apple only) | ✅ High (Works everywhere) |
Most online converters ask you to upload your personal photos to their servers. You have no idea who sees them, how long they are stored, or if they are sold. For family photos or documents, this is a huge risk.
We have solved this.
We have updated our tool to support HEIC files natively. Because we use advanced browser technology, your photos never leave your device. The conversion happens 100% on your phone or computer processor.
How to do it:
It is fast, free, and completely private.
If you prefer to stop your iPhone from taking HEIC photos altogether, you can tell it to save them as JPGs by default. This will use up more storage space, but your photos will be compatible everywhere instantly.
If you just need to convert one photo quickly without a tool, try sharing it via email.
When you open a photo in the iOS Photos app and share it to the Mail app, Apple automatically converts the file to JPG to ensure the recipient can read it. You can email it to yourself and download the JPG attachment.
However, for bulk conversion or keeping photos on your device, Solution 1 is much faster.
