What is HEIC?
HEIC (High Efficiency Image Container) is Apple's image format, adopted as the default for iPhones since iOS 11 in 2017. It uses the HEVC (H.265) compression algorithm — the same technology used for 4K video — to produce files that are roughly 50% smaller than JPG at the same visual quality.
A typical 12MP iPhone photo takes about 1.5 MB as HEIC versus 3 MB as JPG. That means your iPhone can store twice as many photos in the same space.
What is JPG (JPEG)?
JPG (Joint Photographic Experts Group) has been the standard image format since 1992. It's supported by every browser, every operating system, every app, every website, and every printer on the planet. JPG uses lossy compression — it discards some visual data to reduce file size, but the trade-off is nearly invisible at high quality settings.

When to Use HEIC
Keep HEIC when you're staying within the Apple ecosystem — storing photos on your iPhone, sharing via AirDrop to other Apple devices, or backing up to iCloud. The 50% file size savings are significant if you take thousands of photos.
When to Convert to JPG
Convert HEIC to JPG when you need to:
- Share photos with Windows or Android users
- Upload images to websites, forms, or social media
- Edit photos in non-Apple software (Photoshop, GIMP, Canva)
- Attach images to email (some clients can't display HEIC)
- Print photos at a photo lab or kiosk
How to Stop iPhone from Saving HEIC
If you want JPG by default: Settings → Camera → Formats → Most Compatible. This saves future photos as JPG. Note: file sizes will roughly double, so make sure you have enough storage.

Why does iPhone use HEIC instead of JPG?
Apple adopted HEIC in 2017 because it saves 50% storage space at equal quality. You can store twice as many photos on your iPhone.
Does converting HEIC to JPG lose quality?
At 95% quality, the visual difference is imperceptible. Set to 100% for maximum preservation.
Can Windows open HEIC files?
Windows 10/11 can after installing the free HEIF Image Extensions from the Microsoft Store. Alternatively, convert HEIC to JPG online without installing anything.
