Image Format Comparison

HEIF vs JPG: Apple's Modern Photo Format vs the Classic Standard

HEIF (High Efficiency Image File Format) is the container behind HEIC photos from iPhones, using HEVC compression to deliver dramatically smaller files without visible quality loss. JPG has been the universal photo format since the early 1990s. HEIF wins on technical merit — better compression, more colour depth, HDR support, transparency — but JPG wins on compatibility. The choice is often forced by where the image will be used: iPhone camera → HEIF; anywhere else → JPG.

Quick Verdict

Use HEIF when…

Use HEIF (HEIC) for on-device photo storage on iPhone and iPad — it provides 50% smaller files with better quality and supports Live Photos, depth maps, and HDR in a single container.

Use JPG when…

Use JPG for any photo that needs to be shared, uploaded, emailed, or displayed on a website — universal support makes JPG the safe choice when you don't control the recipient's software.

Frequently asked questions

Is HEIF better quality than JPG?

At similar file sizes, yes — HEIF's HEVC-based compression preserves more detail with fewer artefacts than JPG's DCT algorithm. HEIF also supports 16-bit colour (vs JPG's 8-bit), enabling better HDR and wide colour gamut photos. For identical compression level, HEIF is visually superior.

Does Windows 11 open HEIF files?

Windows 11 supports HEIF with the free 'HEIF Image Extensions' from the Microsoft Store. For HEVC video and HEIC photos, you may also need 'HEVC Video Extensions' ($0.99 or free from device manufacturers). Once installed, Photos and File Explorer show HEIF/HEIC files normally.
