How to Convert HEIC to JPG on Windows & Mac (Free, No Upload)

If your iPhone photos won't open on Windows, show up as .HEIC files, or get rejected when you try to upload them somewhere, you're in the right place. This guide fixes it in under a minute — free, with no install, no signup and no watermark.

Why are your photos in HEIC format?

Since iOS 11, iPhones and iPads have saved photos as HEIC (High Efficiency Image Container) by default. It's a genuinely smart choice for your phone — a HEIC is roughly half the size of a JPG at the same visual quality, which saves a lot of storage over thousands of photos.

The catch is that the rest of the world never fully caught up. HEIC isn't universally supported: Windows often can't preview it, many websites reject it when you upload, and older photo editors don't recognise it at all. Converting to JPG — still the most widely supported image format anywhere — fixes every one of those problems at once.

The fastest way: convert in your browser (no software)

You don't need to buy Microsoft's HEIF extension or install anything. Our HEIC to JPG converter runs entirely in your browser — your photos are never uploaded, they're processed right on your own device. Here's the whole process:

• Open the converter.
• Drag your HEIC file(s) in, or click to choose them.
• They convert automatically — then click Download.

Because the work happens on your device, it works even on a slow connection and keeps personal photos private — they never travel across the internet to a stranger's server.

How to convert HEIC to JPG on Windows

Windows 10 and 11 don't open HEIC out of the box on most installs — you'll typically see a prompt to buy the HEIF Image Extensions. Instead of paying for that, do this:

• Copy your photos to your PC (via cable, iCloud for Windows, or even email to yourself).
• Drop them into the browser converter.
• Download the JPGs.

The converted files now open everywhere on Windows — Photos, Paint, Office, and any website that accepts JPG uploads.

How to convert HEIC to JPG on Mac

Macs open HEIC natively, so you can already view them in Preview and Photos. But you'll still need JPG for sites that reject HEIC, or when you're sharing photos with someone on Windows. Preview's File → Export can change one image at a time, but the browser converter is faster for batches and behaves identically across every device — handy if you switch between a Mac and a PC.

How to stop your iPhone making HEIC files

If you'd rather your iPhone just shot JPGs from now on, open Settings → Camera → Formats and tap "Most Compatible". Your phone will shoot JPG going forward. Note that this only affects new photos — the HEIC files already in your camera roll still need converting.

Will I lose quality converting HEIC to JPG?

JPG is a lossy format, so technically there's a tiny bit of compression involved. But at high quality the difference is invisible for normal photos — for sharing, printing or uploading, the JPG looks identical to the original. If you want lossless output instead, the converter can also export PNG.

Frequently asked questions

What is a HEIC file?

It's the default iPhone and iPad photo format since iOS 11 — about half the size of a JPG at the same quality, but unsupported by many Windows apps and websites.

Are my photos uploaded to a server?

No. Conversion happens entirely in your browser; your photos never leave your device.

Can I convert multiple HEIC files at once?

Yes — drag in as many as you like, convert them in one batch, and download them together.

Why won't my HEIC file open on Windows?

Windows doesn't support HEIC out of the box. Converting to JPG is simpler than installing extra software, and the result opens everywhere.

Does converting reduce quality?

Minimally — at high quality the difference is invisible to the eye.
