APK2Mobile is a free and wireless service that allows you to transfer APK files from your Windows PC to any Android device. With a simple three-step process, you can easily upload an APK file from your PC to a private and anonymous cloud. Once uploaded, APK2Mobile generates a QR code and a short link, which you can use to download the file on your Android device. Whether you choose to scan the QR code or use the short link, APK2Mobile ensures a fast and secure transfer. It is important to note that before installing an APK file, you need to enable "Unknown sources" in your Android settings. APK2Mobile is compatible with all Windows versions from XP to 10 and supports APK files up to 100MB in size.
