On a jailbroken iPhone, you can use Theos to write a dynamic library (dylib) that hooks into the app at runtime, overriding functions without editing the IPA directly. This is safer and more powerful.
Original IPAs are code-signed by Apple. Modifying anything breaks the signature. You must re-sign it with a valid provisioning profile.
Using iOS App Signer (macOS):
Without a Mac: You can use services like SignTools or E-Sign (Windows), but they require a paid developer certificate for installation beyond 7 days.
Look for AppIcon60x60@2x.png inside the .app bundle. Replace it with your own PNG (same size and filename). For modern IPAs, icons are inside Assets.car. Use Asset Catalog Tinkerer to extract/replace. edit ipa
Many users search “edit IPA on iPhone” – is it possible?
With a jailbroken iPhone, yes:
Without jailbreak? Impossible. iOS protects the sandbox. You cannot modify an installed app’s bundle.
So “edit IPA” on non-jailbroken device requires you to sideload a modified, re-signed IPA – but that modification must be done on a computer. # Unpack
