Short answer
HEIC (High Efficiency Image Container) has been the default iPhone photo format since iOS 11; Apple's official documentation confirms it produces files roughly 40–50% smaller than JPEG at equivalent visual quality, and it supports 16-bit color depth versus JPEG's 8-bit ceiling, preserving more highlight and shadow detail. The main tradeoff is compatibility — older Windows software, some web upload forms, and non-Apple workflows may not accept HEIC natively, though support has broadened considerably since 2018. For most users in an Apple-centric workflow, staying on HEIC is the better choice; iOS automatically converts to JPEG when you share to incompatible destinations (email, AirDrop to non-Apple device), and you can switch globally to JPEG at Settings > Camera > Formats > 'Most Compatible' if your workflow demands it.
Unblurry helps with this on your iPhone and works on device for privacy — a pay-once app with no subscription. Test it on a real example and check the current App Store listing for details.
What to look for before choosing
- HEIC is ~40–50% smaller than JPEG at the same visual quality (Apple's own comparison)
- 16-bit color depth vs JPEG's 8-bit — HEIC retains more HDR highlight/shadow data for editing
- Supported natively on iOS 11+, macOS High Sierra+, and Windows 10 version 1803+ with Apple codecs installed
- Switch to JPEG globally: Settings > Camera > Formats > 'Most Compatible' (affects new captures only, not existing library)
- iOS auto-converts HEIC → JPEG when sharing via AirDrop to non-Apple devices or via email to incompatible recipients

Quick comparison
| Need | What to check | Why it matters |
|---|---|---|
| Pricing model | Check whether useful features require a subscription, a one-time unlock, or neither. | The cheapest app on day one may not be cheapest after a year. |
| Privacy model | Prefer on-device work when the content is sensitive. | Private documents, resumes, study data, and family content deserve careful handling. |
| Export / lock-in | Confirm file formats, sharing, backup, and deletion controls. | A good app should help you finish the task, not trap your work. |
