Why iPhone Photos Use HEIC
Apple switched the default camera format to HEIC (High Efficiency Image Container) because it stores photos at roughly half the size of JPEG with similar visual quality. That is great on your iPhone, but Windows PCs, many Android apps, and older web upload forms still expect .jpg files. When someone AirDrops vacation photos to a Windows laptop, double-clicking often shows a blank icon or “unsupported format” error.
This converter decodes HEIC locally with WebAssembly — the same class of technology used by privacy-focused tools — and re-encodes to standard JPEG. No iCloud upload, no account, no watermark on downloads. Drag files from Files, Photos export, or email attachments saved to disk.
Windows and Android Compatibility
After conversion, JPGs open in Photos, Paint, Lightroom imports, Slack attachments, and legacy CMS upload fields. For a full album, multi-select every HEIC and download one ZIP of JPGs instead of converting one-by-one.
