Why won’t my iPhone photos open on Windows?
Since iOS 11, iPhones save photos as HEIC (High Efficiency Image Container) to halve file size at the same quality. Windows apps, older Android phones, corporate upload forms, and many email clients still expect JPG. The photo isn’t broken — the receiver just can’t decode HEIC. Converting to JPG solves it permanently, and you can do it free in under a minute without installing anything.
Method 1: Browser converter (fastest, no upload)
- Open the free HEIC to JPG converter on any device — iPhone Safari, Windows Chrome, or Mac.
- Select one or more .heic / .heif files.
- Download the JPG copies. Conversion runs locally, so family photos never touch a server.
Method 2: Change iPhone camera settings (future photos)
On iPhone, go to Settings → Camera → Formats and choose Most Compatible. New photos will save as JPG directly. Trade-off: JPG files are roughly twice the size of HEIC, so storage fills faster. This does not convert photos you already took — use Method 1 for those.
Method 3: Share/export tricks (no settings change)
iOS converts HEIC to JPG automatically in some flows: emailing a photo from the Photos app, or copying photos to a PC with “Automatic” transfer mode (Settings → Photos → Transfer to Mac or PC). These are hit-or-miss for batches, which is why a browser converter is more reliable for a folder of vacation shots.
After converting: shrink or PDF your JPGs
JPGs from a modern iPhone are large. Before emailing, run them through the image compressor (50–70% smaller, same look), or combine several into a single document with JPG to PDF — handy for insurance claims and job applications. Everything runs in your browser; see why that matters for privacy.
