HEIC is the default photo format on iPhones since iOS 11. It produces smaller file sizes at equivalent quality to JPG. The problem is that Windows 11 does not support HEIC natively, so photos transferred from an iPhone often appear as blank icons or trigger an error when opened.
Converting them to JPG fixes the compatibility issue permanently. Here are the two best free methods.
Method 1: The Photos App for Single Files
This method converts one file at a time and uses tools already on your PC. It requires the HEIF Image Extensions codec, which is free from the Microsoft Store and may already be installed.
Step 1: Install the HEIF Image Extensions
Open the Microsoft Store by pressing the Windows key and searching for Microsoft Store. Search for HEIF Image Extensions and install it. Without this codec, the Photos app cannot open HEIC files. Skip this step if it is already installed.
Step 2: Open the HEIC File
Locate your HEIC file in File Explorer. Right-click it and select Open with, then choose Photos. The image opens normally.
Step 3: Save as JPG
Click the three-dot menu in the top right corner of Photos. Select Save as. In the file type dropdown, change the format to JPG. Choose a save location and click Save.
The JPG file saves immediately. Repeat for each file you need to convert.
Method 2: iMazing HEIC Converter for Batch Conversion
For converting dozens or hundreds of photos at once, iMazing HEIC Converter is the best free option available. It converts entire folders in one pass, preserves EXIF metadata including GPS location and date taken, requires no account, and processes everything locally without uploading your photos anywhere.
Step 1: Download and Install
Go to imazing.com/heic and download iMazing HEIC Converter. It is a standalone free tool, completely separate from the paid iMazing iOS manager. Install it normally.
Step 2: Add Your Files
Open iMazing HEIC Converter. Drag and drop your HEIC files or an entire folder into the app window. It accepts hundreds of files at once.
Step 3: Convert
Confirm the output format is set to JPEG. Adjust quality if needed. Click Convert. The app saves JPG versions alongside the originals or in a destination folder you choose. One hundred files typically convert in under a minute.
Preventing the Problem at the Source
If you regularly transfer photos from an iPhone to a Windows PC, configure the iPhone to shoot in JPG instead. Go to Settings, Camera, Formats and select Most Compatible. New photos save as JPG automatically. No conversion needed.
Frequently Asked Questions
Does converting HEIC to JPG reduce image quality?
Slightly. JPG uses lossy compression, which discards some image data. The difference is not noticeable at high quality settings in normal viewing. JPG files are also typically larger than HEIC files at equivalent visual quality, which is the trade-off for broader compatibility.
Why do my HEIC files show as blank icons in Windows 11?
Windows 11 does not include HEIC support by default. Installing the HEIF Image Extensions codec from the Microsoft Store restores thumbnails and allows HEIC files to open in Photos and Paint without conversion.
Does iMazing HEIC Converter cost anything?
No. It is completely free with no account, subscription, or payment required. It processes files locally on your computer without uploading anything to external servers.
