How to Create Your Own IPA File from Any App

By Updated on

What Is an IPA File and Why Would You Create One?

An IPA file (iOS App Archive) is the package format that iOS uses to distribute and install applications. Every app on your iPhone — whether from the App Store or sideloaded — started as an IPA at some point. If you have ever wanted to create your own IPA file, whether to distribute an app you built, preserve an older version of an app, or package a modified app for personal use, this guide walks you through everything you need to know.

Before diving into creation, it helps to understand what is inside an IPA. Our detailed breakdown in understanding IPA files — what they are and how to use them explains the internal structure. In summary, an IPA is a ZIP file containing the app bundle (.app folder), resources, compiled binaries, and metadata.

Method 1: Export an IPA from Xcode

If you are a developer with access to an Xcode project, exporting an IPA is straightforward. This is the most reliable and officially supported method.

Step 1: Open Your Project in Xcode

Open Xcode (version 15 or later recommended) and load your project or workspace file. Make sure your project builds successfully for a physical device (not just the simulator).

Step 2: Select the Right Scheme and Destination

In the toolbar, select your app’s scheme and choose Any iOS Device (arm64) as the destination. This ensures the compiled binary is compatible with real hardware.

Step 3: Archive the App

Go to Product > Archive. Xcode will compile your app and create an archive. This may take a few minutes depending on your project size. When complete, the Organizer window will open automatically.

Step 4: Distribute the App

In the Organizer window, select your archive and click Distribute App. You will be presented with several options:

  • App Store Connect — for App Store submission (not relevant here)
  • Ad Hoc — installs on specific registered devices
  • Development — for development devices
  • Enterprise — for internal distribution (requires Enterprise account)

Select Development or Ad Hoc and follow the prompts. At the end, choose Export to save the IPA file to your Mac.

Method 2: Create an IPA from an Existing App on Your Device

If you want to create an IPA from an app already installed on your iPhone (for backup purposes or personal use), you need a jailbroken device or access to an iTunes backup from an older version of macOS.

Using a Jailbroken Device

On a jailbroken iPhone, tools like IPA Library or Filza File Manager can extract the decrypted app binary from the device and package it as an IPA. The key step is decrypting the binary — App Store apps are encrypted with FairPlay DRM, which can only be removed on the device where the app is licensed.

  1. Install Filza or a similar file manager via Cydia or Sileo.
  2. Navigate to /var/containers/Bundle/Application/.
  3. Find your app’s folder (they are identified by UUID, so you may need to check the Info.plist to find the right one).
  4. Compress the .app folder and rename it to Payload, then zip the Payload folder and rename the .zip to .ipa.

Note: This creates an encrypted IPA. To create a decryptable version for sideloading, you need an additional decryption step using tools like frida-ios-dump or CrackerXI.

Using Old iTunes Backups

In older versions of iTunes (before Apple removed the App Store), iTunes stored a copy of purchased apps as IPA files in ~/Music/iTunes/iTunes Media/Mobile Applications/. If you have such a backup, those IPA files are already packaged and ready to use — though they will need resigning before sideloading.

Method 3: Build a Simple IPA Manually

For developers who want to understand the structure or create a minimal test IPA, you can build one from scratch. This is primarily useful for testing your sideloading workflow with a known-good test app.

  1. Create a minimal iOS app in Xcode (even the default “Hello World” template works).
  2. Build for device: xcodebuild -scheme MyApp -configuration Release -sdk iphoneos build
  3. Find the built .app bundle in the DerivedData folder.
  4. Create a Payload directory: mkdir Payload
  5. Copy the .app into Payload: cp -r MyApp.app Payload/
  6. Zip it: zip -r MyApp.ipa Payload

You now have a basic IPA file. Before it can be installed on a device, it needs to be signed with a valid certificate — which is where Scarlet iOS or another signing tool comes in.

Packaging Tweaked or Modified Apps as IPA

A common reason to create your own IPA is to bundle modifications or tweaks into an existing app. This is known as “patching” an IPA and involves injecting dynamic libraries (dylibs) into the app bundle.

Tools for Patching

  • Patchelf / insert_dylib — command-line tools for injecting dylibs
  • Azule — a modern tool specifically for injecting Cydia Substrate tweaks into IPAs
  • TrollStore IPA Patching — specific to TrollStore but demonstrates the concept

Once you have injected your modifications, repackage the app bundle as described above and sign it with Scarlet iOS or your developer certificate.

Installing Your Custom IPA with Scarlet iOS

Once you have your IPA file ready, installing it via Scarlet iOS is straightforward. See our full walkthrough on how to sideload apps on iOS 18 without jailbreak for the complete installation process. In brief:

  1. Transfer the IPA to your iPhone via AirDrop, iCloud Drive, or a direct URL.
  2. Open Scarlet iOS and tap the + button.
  3. Select your IPA file from Files or enter its URL.
  4. Tap Install and wait for Scarlet to sign and install the app.
  5. Trust the certificate in Settings if prompted.

Legal and Ethical Considerations

Creating IPA files from apps you own for personal backup purposes is generally considered acceptable use. However, distributing IPA files of App Store apps violates Apple’s developer agreement and may infringe on copyright. Always ensure you have the right to distribute any IPA file you create, and only use these techniques for apps you have purchased or built yourself.

Conclusion

Creating your own IPA files opens up a world of possibilities — from preserving app versions to testing your own software to customizing apps for personal use. With the right tools and a solid understanding of the process, anyone can become proficient at IPA creation and management.
