How to convert HEIC to JPG without installing anything

You AirDrop 47 photos from your iPhone to your Windows PC. You open the folder. Every file ends in .heic. Double-click one and Windows asks you to pay for a codec from the Microsoft Store.

This happens because Apple uses HEIC as the default photo format on every iPhone since iOS 11. It compresses photos to roughly half the size of JPG with the same visual quality. Great for saving storage on your phone. Not great when you need to share those photos with anyone who isn’t on a Mac.

The quick fix

1. Open the HEIC to JPG converter
2. Drop your .heic files onto the page
3. Download the .jpg versions

That’s it. The conversion runs in your browser using WebAssembly. Nothing gets uploaded to a server.

Got a whole folder to convert? Use the Convert Image tool instead. Drop multiple files at once and they’ll download as a ZIP.

Why not just shoot in JPG?

Your iPhone has this option buried in Settings > Camera > Formats > Most Compatible. Switching to it means every photo takes up twice the storage. If you’re already bumping against your iCloud limit, that’s a real cost.

The better approach: keep HEIC on for daily use and convert to JPG when you need to share outside Apple’s ecosystem.

Where HEIC causes problems

• Windows: No native support without a paid codec or third-party viewer
• Android: Partial support, depends on the app and OS version
• Email attachments: Most email clients display JPG inline but show HEIC as a generic download
• Web uploads: Many form upload fields don’t accept .heic files
• Printing services: Online print shops almost always expect JPG or PNG

Will I lose quality?

JPG uses lossy compression, so there is a small reduction compared to the HEIC original. For photos, the difference is invisible at normal viewing sizes. If you’re working with graphics or screenshots where every pixel matters, convert to PNG instead for a lossless result.
