What is HEIC Format and Why Does It Matter?

HEIC (High Efficiency Image Container) is Apple's default photo format for iPhones since iOS 11 (2017). It uses advanced compression technology (HEVC/H.265) to create files that are 50% smaller than JPG while maintaining the same visual quality.

Why HEIC Isn't Supported Everywhere:

• Windows 10/11 requires a paid codec to open HEIC files
• Many photo editing software (older versions of Photoshop, Lightroom) don't support HEIC
• Email clients and social media platforms may not accept HEIC uploads
• Older devices and operating systems can't display HEIC images

When to Convert HEIC to JPG:

• Sharing photos with non-iPhone users
• Uploading images to websites or platforms
• Editing photos in desktop software
• Archiving photos for long-term compatibility
• Opening images on Windows without installing codecs

Method 1: Convert HEIC to JPG Online (Recommended)

Best for: Most users who want fast, private, and unlimited conversions without installing software.

4. Convert each image individually (time-consuming for large batches)

Alternative: Use ConvertFast for faster batch processing without software installation.

Frequently Asked Questions

Will I lose quality when converting HEIC to JPG?

Minimal quality loss occurs during conversion, but it's virtually imperceptible to the human eye. If you use a quality setting of 85% or higher, your JPG images will look identical to the original HEIC files.

ConvertFast uses advanced conversion algorithms to preserve maximum quality while creating universally compatible JPG files. The slight compression applied during JPG encoding is necessary for compatibility but doesn't noticeably affect visual quality.

Can I convert HEIC to JPG for free?

Yes! ConvertFast is 100% free with unlimited conversions. There are no daily limits, no file size restrictions, and no hidden fees. You can convert as many HEIC images as you need, whenever you need.

Unlike other "free" converters that limit you to 5-10 files per day or require paid upgrades, ConvertFast provides truly unlimited access forever.

Is it safe to convert HEIC files online?

With ConvertFast, absolutely. Unlike traditional online converters that upload your photos to their servers, ConvertFast uses client-side processing. This means your iPhone photos are converted directly in your web browser and never leave your device. No one—including us—can access your images.

How it works:

• Images are processed using browser-based JavaScript libraries
• No server uploads or storage
• No tracking or image analysis
• Files are deleted from memory immediately after conversion

This approach provides the same privacy as desktop software while offering the convenience of online access.

How long does HEIC to JPG conversion take?

With ConvertFast, conversion is instant. Since processing happens in your browser (no upload required), single images convert in under 1 second. Batches of 100 images typically complete in 10-30 seconds, depending on your device's performance.

Factors affecting speed:

• Number of images being converted
• Original file sizes (larger photos take slightly longer)
• Your device's processing power
• Browser performance

Even on older devices, ConvertFast remains significantly faster than traditional upload-based converters.

Can I convert multiple HEIC files at once?

Yes! ConvertFast supports batch conversion of up to 100 HEIC files simultaneously. Simply select all your iPhone photos, drop them into the converter, and download them all as a convenient ZIP file.

Batch conversion benefits:

• Save time—convert entire photo albums in seconds
• Consistent quality settings across all images
• One-click download of all converted files
• No need to repeat steps for each photo

Do I need to install software to convert HEIC to JPG?

Advantages of browser-based conversion:

• Works on any operating system
• No storage space used on your device
• Always up-to-date (no updates to install)
• No compatibility issues or codec requirements

Why are my iPhone photos in HEIC format?

Apple switched to HEIC as the default photo format in iOS 11 (2017) to save storage space. HEIC files are 50% smaller than equivalent JPG files while maintaining the same quality, allowing you to store more photos on your iPhone.

To prevent iPhone from saving HEIC photos:

1. Go to Settings > Camera
2. Tap "Formats"
3. Select "Most Compatible" instead of "High Efficiency"
4. New photos will be saved as JPG instead of HEIC

Note: Changing this setting only affects new photos. Existing HEIC photos will need to be converted.

Can I convert HEIC to JPG on my phone?

Yes! ConvertFast works on mobile devices through your mobile browser. Simply visit convertfast.io/heic-to-jpg on your iPhone or Android device, upload HEIC files from your photo library, and download the converted JPG images.

Mobile conversion tips:

• Use Safari on iPhone or Chrome on Android for best performance
• Smaller batches (10-20 images) work better on mobile devices
• Ensure stable internet connection (though conversion happens offline)
• Download files immediately to your device's download folder
