Frequently Asked Questions
Why does my iPhone save photos as HEIC instead of JPG?
Apple uses HEIC (High Efficiency Image Container) because it provides better compression than JPG at equal or higher visual quality. However, many Windows and web apps cannot open HEIC natively.
Is it safe to convert private photos here?
Absolutely. Unlike other online converters that upload your personal photos to their cloud servers, ZapyNext converts everything locally inside your browser using WebAssembly.
