HEIC: what it’s for

HEIC (High Efficiency Image Container) is Apple's default iPhone photo format: roughly half the size of JPG with 10-bit color, Live Photos, and burst support. The catch is compatibility — most non-Apple software cannot open HEIC, so convert to JPG or PNG before sharing anywhere.

Strengths

  • About 50% smaller than JPG at equivalent quality
  • 10-bit color and Live Photos, bursts, and depth data in one file
  • Default on iPhones, so no settings change needed to benefit
  • Our tools decode HEIC locally via heic2any — nothing uploads

Honest limits

  • Browsers cannot decode HEIC natively or encode it at all — no tool on this page writes HEIC, only reads it
  • Windows and Android support is spotty; always convert before sharing cross-platform
  • HEIC-to-WebP and HEIC-to-AVIF paths are unreliable (decoder output limits), so convert to JPG or PNG
  • Live Photo motion and depth data do not survive conversion — you keep the still

HEIC FAQs

Why can't I open HEIC photos on Windows?

Windows needs a paid HEIC extension most PCs lack. Convert HEIC to JPG instead — universal, and visually identical for sharing.

Can I convert JPG back to HEIC?

No — browsers have no HEIC encoder, so no web tool here can write HEIC. This is a platform limitation, not a missing feature.

Do HEIC conversions keep photo quality?

Yes. HEIC is decoded losslessly in memory, then exported at high quality (JPG 0.92) — the still you get matches what you saw on the iPhone.

Are my iPhone photos uploaded?

Never. HEIC decoding runs locally in your browser via WebAssembly; photos stay on your device.
