Online AAB to APK: How to Convert Android App Bundles to APK Files
If you are an Android developer or user, you might have heard of the Android App Bundle (AAB) format. It is a new way of packaging and distributing Android apps that offers many advantages over the traditional APK format. However, there might be some situations where you need to convert an AAB file to an APK file, such as testing, debugging, or sideloading apps. In this article, we will explain what an AAB file is, how it differs from an APK file, and how you can convert one to the other using different methods.
What is an AAB file and what are its benefits?
An AAB file is a publishing format that includes all your app's compiled code and resources, and defers APK generation and signing to Google Play. Google Play uses your app bundle to generate and serve optimized APKs for each device configuration, so only the code and resources that are needed for a specific device are downloaded to run your app. You no longer have to build, sign, and manage multiple APKs to support different devices, and users get smaller, more-optimized downloads.

Some of the benefits of using AAB files are:
Size reduction: App bundles help in reducing a significant amount of application size by delivering only the necessary components for each device. On average, app bundles are 15% smaller than universal APKs.
Increased app installations and decreased uninstallations: Apps with smaller size can improve installation success rates and reduce uninstalls.
Higher efficiency: App bundles enable dynamic delivery of features and resources on demand, saving storage and bandwidth.
Faster downloads: App bundles allow users to download apps faster by reducing the download size.
Future improvements: App bundles also support new features such as Play Asset Delivery, Play Feature Delivery, and APK Signature Scheme v4.
What is an APK file and how is it different from AAB?
An APK file is a package file used by Android devices to install apps. It contains all of your app's code, resources, assets, certificates, and manifest file. An APK file can be generated from source code written in either Java or Kotlin.
Some of the differences between APK and AAB files are:
An APK file can be installed directly on an Android device or emulator, while an AAB file cannot. An AAB file needs to be uploaded to Google Play or converted to an APK file first.
An APK file is specific for a certain device configuration, while an AAB file contains all the possible configurations for your app. An AAB file can generate multiple APK files for different devices.
An APK file has a fixed size limit of 100 MB, while an AAB file has a compressed download size limit of 150 MB. An AAB file can also use asset packs or feature modules to deliver large assets or features separately.
Why would someone want to convert AAB to APK?
While AAB files are the preferred publishing format for Android apps on Google Play, there might be some reasons why you would want to convert them to APK files. Some of them are:
You want to test your app on a local device or emulator before uploading it to Google Play.
You want to debug your app using tools that require an APK file.
You want to sideload your app on devices that do not have access to Google Play or support app bundles.
You want to distribute your app through other channels How to convert AAB to APK using bundletool
One of the ways to convert an AAB file to an APK file is to use a command-line tool called bundletool. Bundletool is the same tool that Google Play uses to generate APKs from app bundles. You can use it to generate APKs for specific device configurations or a universal APK that works on all devices.
To use bundletool, you need to follow these steps:
