XAPK is a bundle format that combines an APK file with its additional data files (OBB files) into a single download. This format is especially common for large games and multimedia apps that require extra data beyond the base APK.
An XAPK file is an archive that contains the main APK plus one or more OBB (expansion) files. It allows large apps and games to be distributed as a single file. Apps like PUBG Mobile, Free Fire, and large games often use the XAPK format.
Installing an XAPK file requires a dedicated XAPK installer app. Popular options include the APKPure app, XAPK Installer, and Uptodown's app. These tools automatically extract and install both the APK and OBB files to the correct locations.
Several trusted platforms offer XAPK downloads for Android. APKPure is the most well-known, offering thousands of apps in XAPK format. Uptodown also supports XAPK downloads and has a dedicated app for one-tap installation.
