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.
Every tool runs in your browser — files never leave your device. Badges say exactly what each tool does with HEIC.
Windows needs a paid HEIC extension most PCs lack. Convert HEIC to JPG instead — universal, and visually identical for sharing.
No — browsers have no HEIC encoder, so no web tool here can write HEIC. This is a platform limitation, not a missing feature.
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.
Never. HEIC decoding runs locally in your browser via WebAssembly; photos stay on your device.
