Converting a ZIP file to an IPA format is a common task for developers and power users who need to prepare iOS applications for sideloading or distribution. While an .ipa file is technically a renamed ZIP archive, simply changing the extension is not enough; the internal structure must follow strict iOS packaging rules. 1. Understanding the Core Difference
