HEIC vs JPEG: Which Image Format Should You Use?
Updated: January 2025
If you own an iPhone, you've probably noticed your photos are saved as HEIC files instead of the traditional JPEG. But what's the difference? Is HEIC actually better? And should you switch back to JPEG? This guide covers everything you need to know.
What is HEIC?
HEIC (High Efficiency Image Container) is the file format Apple adopted in 2017 with iOS 11. It's based on the HEIF (High Efficiency Image Format) standard developed by the MPEG group - the same people behind MP4 video.
HEIC Key Features:
- 50% smaller file size than JPEG at same quality
- Supports 16-bit color (vs JPEG's 8-bit)
- Stores multiple images in one file (Live Photos)
- Supports transparency (like PNG)
- Preserves editing history non-destructively
What is JPEG?
JPEG (Joint Photographic Experts Group) has been the standard image format since 1992. It's universally supported across virtually every device, browser, and application in existence.
JPEG Key Features:
- Universal compatibility everywhere
- Adjustable compression levels
- Supported by all image editors
- No special software needed to view
- Industry standard for 30+ years
HEIC vs JPEG: Side-by-Side Comparison
| Feature | HEIC | JPEG |
|---|---|---|
| File Size | 50% smaller | Larger |
| Quality | Better at same size | Good |
| Color Depth | 16-bit | 8-bit |
| Transparency | Yes | No |
| Compatibility | Apple devices, modern browsers | Everything |
| Windows Support | Requires extension | Native |
| Email/Social | Often needs conversion | Works everywhere |
| Live Photos | Supported | No |
Real File Size Comparison
Here's what the storage difference looks like in practice:
| Scenario | HEIC | JPEG |
|---|---|---|
| Single 12MP photo | ~1.5 MB | ~3 MB |
| 100 photos | ~150 MB | ~300 MB |
| 1,000 photos | ~1.5 GB | ~3 GB |
HEIC saves about 50% storage space on your device
Pros and Cons

Which Should You Use?
Keep using HEIC if:
- You primarily use Apple devices
- Storage space is limited on your iPhone
- You take a lot of Live Photos
- You share mostly through iMessage or AirDrop
Switch to JPEG if:
- You frequently transfer photos to Windows PC
- You share photos via email or social media often
- You edit photos in apps that don't support HEIC
- Compatibility is more important than storage

Conclusion
HEIC is technically superior - it offers better quality at smaller file sizes. However, JPEG's universal compatibility makes it the practical choice for sharing and cross-platform use.
Our recommendation: Keep HEIC enabled on your iPhone to save storage, but convert to JPEG when you need to share with non-Apple users or upload to websites.
