How to Convert HEIC to JPG on Windows — 4 Methods

Why Windows Cannot Open HEIC Files

Since iOS 11, iPhones save photos in HEIC format by default. HEIC files are about 50% smaller than JPG at the same quality — great for phone storage, but a headache on Windows. Windows 10 and 11 can display HEIC in Photos if you install the HEIF Image Extensions from the Microsoft Store (free) plus the HEVC Video Extensions (paid, ~$0.99). But many third-party apps — older Photoshop versions, email clients, web forms, and HR systems — still cannot open them.

Method 1: Browser-Based Conversion (Fastest)

The quickest way to convert without installing anything. Open FileKit HEIC to JPG Converter in Chrome, Edge, or Firefox:

1. Drop one or more HEIC files into the upload area
2. Choose JPG or PNG as the output format
3. Adjust quality if desired (default 90% is recommended)
4. Download converted files individually or as a ZIP

All decoding and encoding runs locally in your browser via WebAssembly. Your photos never leave your computer — ideal for personal or sensitive images.

Method 2: Windows Photos App

If you have the HEIF Extensions installed, you can open HEIC files in the Windows Photos app and save them as JPG:

1. Right-click the HEIC file > Open with > Photos
2. Click the three-dot menu > Save as
3. Change the file type to .jpg and save

This works file-by-file but is tedious for large batches.

Method 3: Change iPhone Settings (Prevent HEIC)

If you want to avoid the conversion step entirely, you can configure your iPhone to shoot in JPG:

1. Go to Settings > Camera > Formats
2. Select “Most Compatible” instead of “High Efficiency”

This doubles photo storage usage but ensures universal compatibility. Alternatively, when transferring via USB, go to Settings > Photos > Transfer to Mac or PC and select “Automatic” to have iOS convert on the fly.

Method 4: Command Line (ImageMagick)

For batch processing, ImageMagick handles HEIC on Windows:

magick mogrify -format jpg *.heic

Requires ImageMagick with HEIF delegate installed.
