3 Ways to Convert iPhone HEIC Photos to JPG
If you own an iPhone, you have probably encountered HEIC files when transferring photos to a Windows PC or sharing them online. HEIC is Apple's default photo format since iOS 11, and while it offers great compression, it is not universally compatible. This guide explains what HEIC is, why Apple uses it, and three easy ways to convert HEIC to JPG.
What Is HEIC?
HEIC (High Efficiency Image Container) is a file format based on the HEIF (High Efficiency Image Format) standard, which uses the HEVC (H.265) video codec for still image compression. Apple adopted HEIC as the default photo format for iPhone starting with iOS 11 in 2017.
Why Does iPhone Use HEIC?
Apple chose HEIC for several compelling reasons:
- File Size: HEIC files are roughly 50% smaller than equivalent JPG files, saving significant storage space on your device.
- Quality: Despite the smaller file size, HEIC maintains better image quality than JPG, with support for 16-bit color depth.
- Features: HEIC supports transparency, image sequences (Live Photos), and depth maps that JPG cannot store.
The Compatibility Problem
While HEIC is excellent, many platforms and applications still do not support it natively. Windows 10/11 requires a paid codec extension, most web platforms do not accept HEIC uploads, and many photo editing tools cannot open HEIC files. Converting to JPG solves all of these compatibility issues.
Method 1: Online Converter (QuickConv) - Recommended
The fastest and most convenient way to convert HEIC to JPG is using an online converter. QuickConv lets you convert HEIC photos directly in your browser with no software installation.
- Visit QuickConv and select the HEIC to JPG converter.
- Drag and drop your HEIC file or click to select it from your device.
- Click "Start Conversion" to begin the process.
- Download the converted JPG file.
QuickConv automatically deletes your files after 24 hours for privacy. No account registration or watermark.
Method 2: macOS Preview App
If you are on a Mac, you can use the built-in Preview app to convert HEIC to JPG:
- Open the HEIC file in Preview (double-click the file).
- Go to File > Export from the menu bar.
- Select JPEG as the format and adjust the quality slider.
- Choose a save location and click Save.
This method works well for individual files but can be tedious for batch conversion of many photos.
Method 3: iPhone Settings (Prevent HEIC)
You can configure your iPhone to always use JPG instead of HEIC for future photos:
- Open Settings > Camera > Formats.
- Select "Most Compatible" instead of "High Efficiency".
Note: This will increase the file size of your photos by approximately 2x. This setting only affects new photos; existing HEIC photos are not converted.
