How to Convert HEIC to JPG on Windows (2026 Guide)

If you've ever transferred photos from your iPhone to a Windows PC, you've probably encountered HEIC files. These High Efficiency Image Container files are Apple's default photo format since iOS 11, but Windows doesn't always play nice with them.

The good news? Converting HEIC to JPG on Windows is straightforward, and you have several options depending on your needs. This guide covers the fastest, most private methods that won't require you to upload your personal photos anywhere.

Why Are iPhone Photos in HEIC Format?

Apple switched to HEIC (High Efficiency Image Container) format because it offers better compression than JPG while maintaining image quality. A HEIC file is typically 50% smaller than an equivalent JPG, which means more photos can fit on your iPhone without sacrificing quality.

The problem? Windows 10 and 11 don't natively support HEIC files without installing additional codecs. When you try to open a HEIC file on Windows, you'll either see an error message or be prompted to install the HEVC Video Extensions from the Microsoft Store (which costs £0.99).

The Fastest Way: Use an In-Browser Converter

The quickest method to convert HEIC to JPG on Windows is to use a browser-based converter that processes files locally on your computer. This means your photos never leave your device, protecting your privacy.

Step-by-Step Instructions:

1. Open your web browser and visit a privacy-focused converter like editfiles.fast/heic-to-jpg
2. Click "Choose files" or drag your HEIC photos onto the page
3. Select JPG as the output format (it's usually pre-selected)
4. Click "Convert" and wait a few seconds
5. Download your converted JPG files

This method works entirely in your browser using JavaScript, so your photos are never uploaded to a server. It's fast, free, and works with unlimited files.

Alternative Method: Windows Photos App

If you've installed the HEVC Video Extensions from the Microsoft Store, you can use the built-in Windows Photos app to convert HEIC files:

1. Right-click your HEIC file and select "Open with → Photos"
2. Click the three dots (•••) in the top-right corner
3. Select "Save as" and choose JPG from the format options
4. Choose a location and save your converted file

This method works well for individual files but becomes tedious if you're converting dozens or hundreds of photos.

Batch Converting Multiple HEIC Files

If you have a folder full of iPhone photos to convert, manually converting each one would take forever. Here are your best options for batch conversion:

Option 1: Browser-Based Batch Conversion

Most modern browser-based converters support batch processing. Simply select all your HEIC files at once (Ctrl+A or Cmd+A), upload them, and convert them all in one go. The converter will process them locally and let you download everything as a ZIP file or individually.

Option 2: Windows PowerShell Script

For advanced users, you can use a PowerShell script to batch convert HEIC files if you have the HEVC codec installed. However, this requires technical knowledge and isn't as straightforward as using a web-based tool.

Why You Should Avoid Uploading Your Photos

Many popular HEIC converters require you to upload your photos to their servers for conversion. While convenient, this raises several privacy concerns:

• Data privacy: You have no control over what happens to your photos once uploaded
• Potential data mining: Some services analyze uploaded images for advertising or training AI models
• Security risks: Photo metadata (location, time, device info) can be extracted
• Slower processing: Uploading and downloading takes longer than local processing

Client-side converters that process files in your browser eliminate these risks entirely. Your files never leave your device, making it impossible for anyone to access them.

Troubleshooting Common Issues

Error: "Can't open this file type"

If Windows won't open HEIC files at all, you'll need to either install the HEVC Video Extensions from the Microsoft Store (£0.99) or use a browser-based converter that doesn't require any codec installation.

Converted Photos Look Different

HEIC files sometimes use a wider color gamut than JPG supports. When converting, some color information may be lost. This is rarely noticeable in everyday photos but can affect professional photography. If color accuracy is critical, consider keeping the original HEIC files as a backup.

Large File Sizes After Conversion

JPG files are typically larger than HEIC files. If file size is a concern, you can compress your JPG images after conversion. Most converters offer quality settings that let you balance file size against image quality.

Should You Convert or Change iPhone Settings?

This depends on your workflow:

Convert HEIC to JPG if:

• You primarily use Windows and want maximum compatibility
• You need to share photos with people who don't have HEIC support
• You're uploading photos to websites that don't accept HEIC

Keep using HEIC if:

• You're in the Apple ecosystem (Mac, iPad, iPhone)
• Storage space on your iPhone is limited
• You don't mind occasional conversion when needed

Final Thoughts

Converting HEIC to JPG on Windows doesn't have to be complicated or risky. Browser-based converters offer the perfect balance of convenience, speed, and privacy. They work without installing software, handle batch conversions easily, and keep your photos completely private.

Whether you're converting a single vacation photo or an entire photo library, choosing a privacy-focused tool ensures your personal memories stay personal.
