If you have a website and you want to launch it as an app on the Google Play Store, you must generate a specific type of file.
Since August 2021, Google no longer accepts the traditional APK file format for new app submissions. Instead, they require developers to submit an AAB (Android App Bundle).
Fortunately, you do not need to hire a developer or learn complex software to generate this file. In this guide, we will show you how to convert a website into an Android App Bundle quickly and easily.
What is an Android App Bundle (AAB)?
Before converting your site, it helps to understand what an AAB actually is.
In the past, an APK contained the code for every possible Android device—tablets, old phones, new phones, different screen sizes, and different language packs. This made the file massive.
An AAB is essentially a master blueprint. You upload the AAB to the Google Play Store. When a user taps "Download" on their specific phone, Google reads the AAB blueprint and extracts only the specific code and images needed for that exact device.
The result? The app downloads much faster and takes up significantly less space on the user's phone.
How to Convert Your Website to an AAB
To convert your website into an AAB, you will use an automated online website-to-app converter.
Step 1: Optimize Your Web Experience
The AAB will contain a WebView—a native browser that displays your mobile website. If your website is slow or has broken links, the app will reflect that. Ensure your site is fully mobile-responsive and uses a secure HTTPS connection.
Step 2: Choose the Right Converter
This is the most critical step. Many older or lower-quality web-to-app converters only generate APK files. You must choose a platform that explicitly states it provides AAB generation or Google Play Store ready files.
Step 3: Configure Your App
Provide the online platform with your branding details:
- Website URL: The exact link to your homepage.
- App Name: The title of your app.
- App Icon: A 512x512 high-resolution PNG of your logo.
Step 4: Add Native Features
If you want your app to feel premium, configure native features like a Splash Screen (a loading screen) and Push Notifications.
Step 5: Compile and Download
Click generate. The platform’s cloud servers will write the necessary Java/Kotlin code, package it, and sign it with a digital certificate.
Within minutes, the platform will output the .aab file. Download this file to your computer.
(Note: You cannot install an AAB directly onto your Android phone for testing. You should also download the APK provided by the platform to test on your own device before publishing the AAB).
Publishing Your AAB
Once you have your AAB file downloaded to your computer, you are ready to publish!
- Create a Google Play Developer account (this requires a one-time $25 fee paid to Google).
- Click Create App in the Google Play Console.
- Fill out your Store Listing (write a description, upload screenshots, and provide your privacy policy).
- Navigate to the Production track and upload your
.aabfile. - Submit your app for review!
Conclusion
Converting a website into an Android App Bundle is a seamless process thanks to modern cloud-based automation tools. By ensuring your website is mobile-ready and utilizing a premium online converter, you can bypass traditional development and submit your app to the Google Play Store today.
