Mobile Photography Tips: When to Use HEIC vs JPG
Modern smartphones, particularly iPhones, have revolutionized photography. However, this advancement brings a new challenge: choosing between HEIC and JPG formats. This decision affects storage space, image quality, compatibility, and sharing ease. This comprehensive guide will help you understand both formats and make informed decisions for different photography scenarios.
Understanding HEIC and JPG
What is HEIC?
HEIC (High Efficiency Image Container) is Apple's modern image format, introduced with iOS 11 in 2017. Based on the HEVC (H.265) video codec, it offers superior compression while maintaining high image quality. Apple adopted HEIC to address the growing storage demands of high-resolution smartphone photography.
What is JPG?
JPG (also spelled JPEG) stands for Joint Photographic Experts Group. It's been the standard for digital photography since 1992, offering universal compatibility and reasonable file sizes through lossy compression.
Side-by-Side Comparison
| Feature | HEIC | JPG |
|---|---|---|
| File Size | ✓ 50% smaller | Standard size |
| Image Quality | ✓ Better at same size | Good |
| Compatibility | ✗ Limited | ✓ Universal |
| HDR Support | ✓ Yes | ✗ No |
| Transparency | ✓ Yes | ✗ No |
| Multiple Images | ✓ Yes (Live Photos, burst) | ✗ No |
| Editing Data | ✓ Preserved | ✗ Not preserved |
| Web Upload | ✗ Often requires conversion | ✓ Works everywhere |
| Social Media | Auto-converts (may lose quality) | ✓ Direct upload |
| Device Support | iOS 11+, macOS High Sierra+, limited others | ✓ All devices |
When to Use HEIC
Scenario 1: Daily iPhone Photography
Use HEIC when: Taking everyday photos that you'll primarily view and share within the Apple ecosystem.
Why: You'll save 50% storage space, maintain better quality, and preserve Live Photos functionality. iCloud Photos handles everything seamlessly, and when you share via Messages or AirDrop to other Apple users, no conversion is needed.
Scenario 2: Storage-Constrained Devices
Use HEIC when: Your iPhone or iPad is running low on storage.
Why: HEIC's 50% file size reduction means you can store twice as many photos. A 64GB iPhone that holds 10,000 JPG photos could store approximately 20,000 HEIC photos with the same or better quality.
Scenario 3: HDR Photography
Use HEIC when: Shooting HDR photos or in situations with high dynamic range (bright skies, dark shadows).
Why: HEIC natively supports HDR, preserving the extended brightness and color range. JPG cannot store HDR data, so you lose this information in conversion.
Scenario 4: Keeping Edit History
Use HEIC when: You frequently edit photos and might want to revert changes later.
Why: HEIC preserves editing metadata, allowing you to undo edits even after saving. JPG editing is destructive - once saved, changes are permanent.
When to Use JPG
Scenario 1: Sharing with Non-Apple Users
Use JPG when: You frequently share photos with Android users, PC users, or upload to websites.
Why: JPG works everywhere without conversion. HEIC files often won't open on non-Apple devices or require manual conversion, creating friction in your sharing workflow.
Scenario 2: Professional/Business Photography
Use JPG when: Taking photos for work, client deliverables, or professional purposes.
Why: Clients and colleagues expect JPG files. Converting HEIC to JPG for every project adds unnecessary workflow steps. Starting with JPG ensures universal compatibility from the start.
Scenario 3: Website and Social Media Content
Use JPG when: Creating content specifically for websites, blogs, or social media platforms.
Why: While major social media apps auto-convert HEIC, many websites, content management systems, and older platforms don't accept HEIC uploads. JPG eliminates compatibility headaches.
Scenario 4: Archived Photos and Backups
Use JPG when: Creating long-term archives or backing up important photos to external storage.
Why: JPG will remain readable for decades on any device. HEIC's long-term compatibility is uncertain, especially as software and operating systems evolve.
Practical Tips for iPhone Users

- Batch convert multiple files simultaneously
Storage Space Comparison
Real-world storage savings with HEIC:
| Number of Photos | JPG Storage (approx) | HEIC Storage (approx) | Space Saved |
|---|---|---|---|
| 100 photos | 300 MB | 150 MB | 150 MB |
| 1,000 photos | 3 GB | 1.5 GB | 1.5 GB |
| 5,000 photos | 15 GB | 7.5 GB | 7.5 GB |
| 10,000 photos | 30 GB | 15 GB | 15 GB |
Note: Actual sizes vary based on image content and camera settings. These are typical values for 12MP photos from modern iPhones.
Common Mistakes to Avoid
HEIC preserves editing history. If you convert to JPG first, you lose this capability. Edit in HEIC, then convert final images to JPG if needed.
Even though iPhone makes sharing easy, HEIC can cause problems for recipients on Android or Windows. Consider your recipient's device before sharing.
HEIC is already compressed. Converting compressed HEIC to JPG can result in quality loss. Work from original HEIC files when converting.
Keep HEIC originals until you're sure JPG versions meet your needs. Storage is cheap; recreating lost quality isn't possible.
Future Outlook
The HEIC vs JPG landscape is evolving:
- Growing HEIC Support: Windows 11 and recent Android versions now support HEIC natively
- Web Adoption: More websites accepting HEIC uploads as browser support improves
- Alternative Formats: WebP and AVIF offer similar benefits to HEIC with better cross-platform support
- Longer Term: JPG will remain the universal standard for years to come due to its massive existing infrastructure
