iPhone Formats & Compatibility
Apple’s camera pipeline optimizes for library size and quality. The formats you shoot are not always the formats the rest of the world accepts. This hub ties iPhone defaults to open guides and converters.
Quick take: iPhones often save HEIC. That is great on Apple gear — convert to JPG when you share with Windows, Android, or the web.

What Image Format Does iPhone Use?
Modern iPhones typically save photos as HEIC (High Efficiency Image Container). You can switch Camera settings to Most Compatible to shoot JPG instead.
Why Does iPhone Use HEIC?
HEIC stores more detail in less space than JPG using HEIF/HEVC. Apple chose it for library efficiency — the cost is weaker support outside Apple devices.
How to Convert iPhone Photos to JPG
Export from Photos as Most Compatible, change Camera formats to JPG going forward, or convert HEIC → JPG privately in the browser with Format Convertly.
HEIC vs JPG for iPhone
HEIC wins on iPhone storage and quality-per-byte. JPG wins on universal compatibility. Keep HEIC masters; share JPG.
How to Change iPhone Photos from HEIC to JPG
Set Camera → Formats → Most Compatible for new JPG photos. Convert existing HEIC files to JPG with Format Convertly when you need shareable copies.
What usually breaks
Emailing HEIC to Windows users, uploading to CMS tools that only accept JPG/PNG, and transferring photos to older Android galleries.
What usually works
AirDrop, iCloud Photos, and Mac Preview handle HEIC natively. For everyone else, JPG is the share currency.
