HEIC vs JPG: Which Image Format Should You Use for Your Photos?
Compare HEIC and JPG image formats for storage, quality, and compatibility. Learn when to keep HEIC and when to convert to JPG.
Apple introduced HEIC (High Efficiency Image Container) as the default photo format starting with iOS 11. It promises 50% smaller files than JPG at the same quality level. But is it always better? Here's a thorough comparison.
What Is HEIC?
HEIC uses HEVC (High Efficiency Video Coding) compression, also known as H.265. This is the same modern codec used for 4K video. For still images, HEIC achieves significantly better compression than JPG's older JPEG standard.
What Is JPG?
JPEG (Joint Photographic Experts Group), commonly saved as JPG, is the most widely supported image format in existence. It uses lossy compression based on discrete cosine transform, a technology from the early 1990s.
Side-by-Side Comparison
| Feature | HEIC | JPG |
|---|---|---|
| File size | ~2.5 MB per 12MP photo | ~5 MB per 12MP photo |
| Quality at same size | Better (HEVC codec) | Standard |
| Transparency | No | No |
| Animation | Yes (burst photos) | No |
| iOS/Apple support | Native (default) | Full support |
| Android support | Partial (Android 10+) | Full support |
| Windows support | Requires HEIF extension | Full support |
| Web browser support | Safari only | Universal |
| Social media upload | Often converted to JPG | Direct upload |
| Editing software | Recent apps only | Universal |
When to Keep HEIC
HEIC is excellent for archiving photos on your iPhone or iPad. You get roughly half the storage usage compared to JPG, which means you can keep more photos on your device. iOS handles HEIC seamlessly — viewing, editing, and sharing within Apple's ecosystem works perfectly.
If you primarily use Apple devices and don't need to share RAW files with Windows or Android users, HEIC is the better everyday format.
When to Convert HEIC to JPG
Convert HEIC to JPG when you need to:
- **Share photos** with friends or colleagues who use Android or Windows
- **Upload to websites** and social media platforms that don't support HEIC
- **Edit in older software** like Photoshop CS6 or earlier (CC 2018+ supports HEIC)
- **Print photos** at a lab that requires JPG format
- **Email attachments** — JPG is universally readable without extra codecs
How to Convert HEIC Photos
You can convert HEIC to JPG online instantly with ConvertAI — no app download needed, works in any browser. If you need to retain maximum quality for further editing, convert HEIC to PNG instead for a lossless intermediate format.
Storage Math
A 64GB iPhone shooting HEIC stores about 25,000 photos. The same phone shooting JPG stores only about 12,500. Over a year of daily photography, HEIC saves roughly 15–20 GB of storage.
Bottom Line
HEIC is technically superior — smaller files at equal quality. But JPG wins on compatibility. Keep HEIC on your iPhone, but convert to JPG before sharing with anyone outside the Apple ecosystem.
