How to Convert HEIC to JPEG on Windows and Mac (The Easy Way)

Updated Feb 3, 2026 • 11 min read • By ImageResizze Tech Support

You transferred your vacation photos from your iPhone to your PC, only to find a folder full of files ending in .HEIC. You try to open them, but Windows says it doesn't recognize the format. You try to upload them to a website, and it gives you an error. Sound familiar?

HEIC (High Efficiency Image Container) is Apple’s standard format. It’s great for saving space on your phone, but it’s a headache for compatibility. In this guide, we’ll show you the absolute easiest ways to convert HEIC to JPEG on any device in 2026—without spending a dime or compromising your privacy.

🔍 What is HEIC?

HEIC is a modern file format that uses advanced compression to make photos about 50% smaller than a JPEG of the same quality. While efficient, it is not yet a universal web standard, which is why conversion is often necessary.

1. The Universal Method: Browser-Based Conversion

The fastest way to convert, regardless of your operating system, is using a local-first web tool. Unlike older websites that require you to "upload" your photos to their server, modern tools like ImageResizze handle the conversion inside your browser.

Step 1: Go to the HEIC to JPG Converter.
Step 2: Drag and drop your .HEIC files into the box.
Step 3: Click "Convert" and download your JPEGs instantly.

Privacy Note: Because this happens locally, your photos never leave your computer.

2. How to Convert on Windows 10 & 11

Windows does not support HEIC natively out of the box, but you can add support or use built-in tools to convert:

The Photos App: Open your HEIC image in the Windows Photos app. Click the three dots (...) and select "Save As." Choose .jpg from the format dropdown menu.
The HEIF Image Extension: You can download this from the Microsoft Store. Once installed, Windows will treat HEIC files like JPEGs, but this doesn't "convert" them for sharing; it only lets you view them.

3. How to Convert on macOS

Mac users have it easiest, as the OS was built to handle HEIC. You have two primary "native" ways to convert:

Using Preview: Open the image in Preview. Go to File > Export. Select JPEG from the "Format" menu and hit save.
Using Quick Actions (Bulk): Highlight multiple HEIC files in Finder. Right-click, go to Quick Actions > Convert Image. Choose JPEG and the desired size. This is the best way to handle dozens of photos at once.

4. Pro Tip: Stop Your iPhone from Using HEIC

If you’re tired of converting, you can tell your iPhone to go back to the classic JPEG format for all future photos:

Go to Settings on your iPhone.
Scroll down to Camera.
Tap Formats.
Select Most Compatible (instead of High Efficiency).
