You transfer photos from your iPhone to a Windows PC and get a folder full of .heic files that nothing will open. Or you try to upload an iPhone photo to a website and get an error. HEIC is Apple's default camera format since iOS 11 — it's more efficient than JPEG but practically invisible outside Apple's ecosystem. This guide explains what HEIC is and the fastest ways to convert it.

What Is HEIC?
HEIC / HEIF
- Default iPhone camera format since iOS 11 (2017)
- ~50% smaller than JPEG at the same visual quality
- Supports transparency, depth maps, image sequences
- Based on the HEVC (H.265) video codec
- Natively supported: iOS, macOS, Windows 11 (with codec)
Why It Causes Problems
- Windows 10 without HEVC codec can't open .heic files
- Android phones can't view HEIC photos
- Most websites (WordPress, Gmail, etc.) reject HEIC uploads
- Photo editing apps often lack HEIC support
- Printing services usually require JPG or PNG

4 Ways to Convert HEIC to JPG
Method 1: Free Online Converter (No Install)
The fastest option — works on any device, no software needed:
- Open the HEIC to JPG Converter
- Drag and drop your .heic files or click to select them
- Choose output format (JPG or PNG) and quality
- Click Convert, then download the result
Method 2: iPhone Settings — Send as JPEG Automatically
Prevent the problem at the source. When you share photos from iPhone (via AirDrop to non-Apple, email, or Messages), iOS can automatically convert to JPEG:
Settings → Camera → Formats → Most CompatibleThis changes new photos to JPEG. Existing photos remain HEIC but iOS will auto-convert when sharing. Note: JPEG photos are roughly 2× the file size of HEIC.
Method 3: Windows — Install HEVC Codec
Windows 11 supports HEIC via the HEVC Video Extensions from the Microsoft Store (free or ~$1 depending on device). After installing, Windows Photos and File Explorer will open .heic files natively.
This is the best option if you frequently work with iPhone photos on Windows, but it doesn't help you convert files to share with others.
Method 4: macOS Preview
On a Mac, open the HEIC file in Preview, then:
File → Export → Format: JPEG → SavePreview supports batch export: select multiple files in Finder, open all in Preview, then File → Export Selected Images.
Should You Convert to JPG or PNG?
| Factor | JPG | PNG |
|---|---|---|
| File size | Smaller (lossy compression) | Larger (lossless) |
| Quality | Slight loss at lower settings | Pixel-perfect, no loss |
| Transparency | Not supported | Supported |
| Best for | Photos, email, web, printing | Screenshots, graphics, editing |
| Compatibility | Universal — supported everywhere | Very widely supported |
Recommendation: For iPhone photos, choose JPG at 85–95 quality. It produces files roughly similar in size to HEIC and is universally compatible with email, websites, and photo services.
Frequently Asked Questions
Will converting HEIC to JPG reduce photo quality?
At 85–95 quality setting, the difference is virtually imperceptible to the human eye. JPG at 90% quality from a HEIC source looks identical for photos, email attachments, and printing. Only at very low quality settings (below 70%) will you see visible compression artifacts.
Why does my iPhone shoot HEIC instead of JPEG?
Apple switched to HEIC in iOS 11 because it stores photos at half the file size of JPEG with the same perceptual quality — freeing up storage space. On Apple devices it's seamless, but compatibility with non-Apple platforms remains limited. You can switch back to JPEG in Settings → Camera → Formats → Most Compatible.
Can I convert multiple HEIC files at once?
Yes — our HEIC to JPG Converter supports batch conversion. Select or drop multiple files at once and download them all when done.
Are my photos private when using the online converter?
Yes. The converter runs entirely in your browser — no files are uploaded to any server. Your photos stay on your device throughout the entire process.
