iPhone Photo Format Settings Guide
Your iPhone shoots photos in HEIC format by default. While HEIC has many advantages, if you frequently share photos with non-Apple users or use software that does not support HEIC, you may want to switch formats. Here is how.
How to Switch iPhone Camera Format
iPhone offers two camera format options:
- Open the Settings app
- Scroll down and tap Camera
- Tap Formats
- Choose High Efficiency (HEIC) or Most Compatible (JPEG)
| Option | Photo Format | Video Format | Best For |
|---|---|---|---|
| High Efficiency | HEIC | HEVC (H.265) | Apple ecosystem users |
| Most Compatible | JPEG | H.264 | Cross-platform sharing |
Tip: Even with "High Efficiency" (HEIC) selected, iOS automatically converts HEIC to JPEG when sharing via AirDrop to Mac or sending via iMessage. However, email attachments and third-party apps do not auto-convert.
Transfer Settings: Automatic Conversion
iPhone also has a "Transfer to Mac or PC" setting that can automatically convert formats during transfer:
- Open Settings > Photos
- Find the Transfer to Mac or PC section
- Choose Automatic (auto-converts to JPEG) or Keep Originals (keeps HEIC)
ProRAW and ProRes
iPhone Pro models offer additional advanced format options:
- Apple ProRAW — Combines RAW data with Apple's computational photography processing; files are approximately 25 MB
- ProRes — Professional video format suited for post-production
These formats are designed for professional photographers and videographers; most users do not need them.
iCloud Photos and Formats
If you use iCloud Photos, keep in mind:
- HEIC photos uploaded to iCloud remain in HEIC format
- When downloading from iCloud.com, you can choose to download as JPEG
- HEIC's smaller file size helps conserve iCloud storage space
Recommended Configurations
Option 1: High Efficiency + Automatic Transfer
Set camera format to "High Efficiency" and transfer setting to "Automatic." You enjoy HEIC's smaller files on your phone, and photos auto-convert to JPEG when transferred to your computer — the best of both worlds.
Option 2: Most Compatible
Shoot directly in JPEG. Ideal for users who frequently use photos across different platforms, eliminating all conversion hassles.
Option 3: High Efficiency + Tool Conversion
Shoot in HEIC to save space, and batch-convert to JPG using an online tool when needed.
Convert HEIC to JPG Now →Conclusion
There is no single "best" setting — only the best setting for your usage habits. If you primarily use photos within the Apple ecosystem, HEIC is the better choice. If you frequently share across platforms, JPEG or the automatic conversion approach is more practical.
