How to Open and Convert Apple HEIC Photos on Windows (Free Guide)

What is a HEIC File and Why Does Apple Use It?

Since the release of iOS 11, Apple iPhones and iPads capture photos in HEIF (High Efficiency Image File Format) with the .heic file extension.

Apple adopted HEIC because it utilizes state-of-the-art HEVC (H.265) compression algorithms:

50% Smaller Storage Footprint: A 12-megapixel camera shot saved as a HEIC file consumes roughly 1.5 MB to 2 MB, whereas the exact same photo saved in traditional JPG format consumes 3.5 MB to 5 MB.
16-Bit Color Depth: Supports up to 16-bit color channels compared to JPG's 8-bit limit, capturing richer sky gradients and shadow detail.
Live Photos & Burst Shots: A single HEIC container can store multiple sequential frames, depth maps, and audio tracks.

Why Windows Cannot Open HEIC Photos Natively

When you transfer photos from an iPhone to a Windows 10 or Windows 11 PC via USB cable, iCloud, or Google Drive, double-clicking them in the default Windows Photos app often produces an error:

"The HEVC Video Extensions from the Microsoft Store is required to view this file."

Because the HEVC codec is subject to commercial patent licensing royalties, Microsoft removed the native decoder from standard Windows installations and charges $0.99 for the extension in the Microsoft Store. Furthermore, many desktop applications, older Photoshop versions, and official website upload forms do not accept the .heic file extension.

Top 3 Ways to Convert HEIC to JPG

Method 1: ConvertNest Free Online HEIC to JPG Converter (Fastest)

The simplest, zero-cost solution that requires no software or paid codecs is the ConvertNest HEIC to JPG Converter.

Walkthrough:

Open the HEIC to JPG Converter in your browser (Chrome, Edge, Firefox, or Brave).
Drag and drop your .heic or .heif photos directly into the converter.
Our high-speed container decoder extracts the raw uncompressed RGB stream and transcodes it into a pristine, high-resolution JPEG.
Download your universal .jpg files ready to open in any software, attach to emails, or print.

💡 Quick Tip: You can drag and drop an entire folder of iPhone photos at once. ConvertNest processes your photos in parallel and lets you download a single clean ZIP archive.

Method 2: Installing the Microsoft HEVC Codec Extension

If you want Windows 10/11 File Explorer to display HEIC thumbnails natively:

Open the Microsoft Store on your PC.
Search for "HEVC Video Extensions" (priced at $0.99 USD) and "HEIF Image Extensions" (Free).
Install both extensions and restart your computer.

Method 3: Configure iPhone to Shoot JPG by Default

If you frequently transfer photos to Windows PCs and prefer universal compatibility from the moment you press the shutter:

Open Settings on your iPhone.
Scroll down and tap Camera.
Tap Formats.
Select Most Compatible (instead of High Efficiency).

Note: Your iPhone will now save camera photos as universal JPGs. Keep in mind that your camera roll will take up approximately 40% to 50% more iCloud and device storage.
