To understand why a conversion works or fails, you need to know what these files actually are.

| If you have… | What you actually need to do… | |--------------|-------------------------------| | A zipped | Unzip, then re-zip as Payload/ folder → rename to .ipa | | Xcode project source | Build & archive in Xcode, export as IPA (requires signing certificate) | | Random files (HTML, assets, etc.) | Cannot become a functional IPA without native iOS code & signing | | Android APK | Use different tooling; cannot convert to IPA |
