HEIC vs JPG: Understanding Apple's Image Format

If you own an iPhone or iPad, your photos are likely saved in HEIC format. This modern format offers better compression than JPG, but its limited compatibility can cause frustration when sharing photos. Here's everything you need to know.

What is HEIC?

HEIC (High Efficiency Image Container) is based on the HEVC (H.265) video codec. Apple adopted it as the default photo format starting with iOS 11 in 2017. HEIC files are approximately 50% smaller than equivalent JPG files while maintaining the same visual quality.

Why Apple Chose HEIC

Storage space. With HEIC producing files half the size of JPG, iPhone users can store twice as many photos in the same space. HEIC also supports features JPG lacks: 16-bit color depth, multiple images in one file (Live Photos), and transparency.

The Compatibility Problem

While HEIC offers technical advantages, it's not universally supported. Windows users, Android devices, many websites, and older software may not open HEIC files. This is the primary reason people need to convert HEIC to JPG regularly.

When to Convert HEIC to JPG

Convert when sharing photos with non-Apple users, uploading to websites that don't support HEIC, or using software that requires JPG. You can convert HEIC to JPG instantly in your browser, and your photos never leave your device.

iPhone Tip: Auto-Convert on Transfer

Go to Settings > Camera > Formats and select "Most Compatible" to shoot in JPG directly. Or keep HEIC for storage benefits and convert only when needed using HEIC to PNG for lossless conversion.
