The APK to AAB Converter is a specialised tool designed to transform Android application packages, or APK files, into Android App Bundles (AAB). This conversion process is essential for modern Android app development and distribution.

In the traditional APK format, developers create a singular file that encompasses all the app's components, leading to larger file sizes and potential compatibility issues across different devices. However, AAB, the next-generation format introduced by Google, aims to overcome these challenges.
