What is an APKS file?

An APKS file is a ZIP archive containing multiple split APK files. It is generated by Android App Bundle (AAB) using bundletool. Split APKs divide an app into base APK plus configuration-specific splits (architecture, screen density, language).

How to merge split APKs into one APK?

Upload your .apks or .zip file to our free APKS to APK Converter at xapktoapk.com. The tool extracts the base APK which contains all essential app code and resources. You can download the base APK or individual split files.

Can I install APKS file directly on Android?

You cannot install an .apks file directly. You need either SAI (Split APKs Installer) to install all splits, or convert it using our APKS to APK converter to get a single installable base APK.

What is the difference between APKS and APK?

APK is a single Android application package. APKS is a container with multiple split APKs optimized for different device configurations. APKS files are typically generated from AAB (Android App Bundle) format.
