How to Convert HEIC to JPG on Windows (Free, No Install)

You just transferred photos from your iPhone to your Windows PC, and… none of them open. You get a message like "Can't open this file" or "No app associated with this file type."

That's because your iPhone saves photos in HEIC format, and Windows doesn't support it out of the box. Super annoying, right?

The good news: converting HEIC to JPG is really easy. Here are your options, from simplest to most involved.

But first — what even is HEIC?

HEIC stands for High Efficiency Image Container. Apple started using it as the default photo format on iPhones in 2017 (iOS 11). The reason? HEIC files are about half the size of JPEGs but with the same quality. That means your phone can store twice as many photos.

The downside is compatibility. Windows, a lot of Android devices, and many websites and apps still don't support HEIC natively. So you end up needing to convert to JPG, which is supported basically everywhere.

Method 1: Convert online — no install, no upload (recommended)

The fastest way is to use our HEIC to JPG Converter. Here's how it works:

1. Open the tool in your browser (Chrome, Firefox, Edge — anything works)
2. Drag and drop your HEIC file onto the page
3. Wait a second or two for the conversion
4. Click download to get your JPG

That's literally it. No software to install. No sign-up. And here's the important part: your photo never gets uploaded anywhere. The conversion happens right in your browser using JavaScript. Your file stays on your computer the whole time.

This is what makes it different from other online converters that upload your photo to their server, process it there, and send it back. With ours, nothing leaves your machine.

Method 2: Install HEVC extensions on Windows

If you want Windows to open HEIC files natively (without converting), you can install the HEVC codec:

1. Open the Microsoft Store
2. Search for "HEVC Video Extensions from Device Manufacturer" (this one is free)
3. Install it
4. Restart your computer

After that, Windows Photos and File Explorer should be able to open HEIC files. The catch? There are two versions of this extension — the free one (from Device Manufacturer) and a paid one ($0.99). Make sure you search for the free version specifically.

Also, some people report this doesn't always work reliably. If it doesn't, just use Method 1.

Method 3: Change your iPhone settings

If you want to prevent this problem entirely going forward, you can tell your iPhone to take photos in JPG instead of HEIC:

1. Open Settings on your iPhone
2. Go to Camera → Formats
3. Select Most Compatible

This switches your camera to save in JPG format. The trade-off is that photos will take up more storage space (roughly 2x). But they'll work everywhere without conversion.

You can also set your iPhone to automatically convert when transferring:

1. Go to Settings → Photos
2. Under "Transfer to Mac or PC", select Automatic

This tells your iPhone to convert HEIC to JPG on the fly when you transfer photos via USB. Pretty handy, but it only helps for USB transfers — not AirDrop, email, or cloud sharing.

Method 4: Use desktop software

If you regularly work with lots of HEIC files, you might want a desktop app. A few free options:

• IrfanView (Windows) — Free image viewer that can open and convert HEIC files. You'll need to install the plugins pack for HEIC support.
• GIMP (Windows/Mac/Linux) — Free and open source. Can open HEIC files and export as JPG.
• XnConvert (Windows/Mac/Linux) — Batch converter that handles HEIC. Good if you have dozens of files to convert at once.

These are all solid options but require installing software. If you just need to convert a few photos quickly, our browser-based converter is faster since there's nothing to install.

Does converting HEIC to JPG lose quality?

Barely. Our converter uses a quality setting of 92%, which is visually identical to the original for everyday use. You'd need to zoom in at 200%+ and compare side by side to notice any difference, and even then it's minimal.

The JPG file might actually be a bit larger than the HEIC file, since HEIC uses more efficient compression. But it'll work everywhere — and that's the whole point.

Quick recap

• iPhones save photos in HEIC format, which Windows can't open by default
• The easiest fix: use our HEIC to JPG converter — free, no install, no upload
• You can also install HEVC extensions from the Microsoft Store
• Or change your iPhone camera to shoot in JPG (Settings → Camera → Formats → Most Compatible)
• Quality loss is negligible — you won't notice any difference in the converted photo
