Auto Sign Multiple APKs and ZIPs Based on Signapk.jar for Windows

The auto-signing tool is a GUI application based on signapk.jar for Windows, and can sign multiple apk and zip files very quickly in one click. It also features a drag and drop function and supports signing with privatekey.pk8 and publickey.x509.pem.

The tool can also sign a mixture of apk and zip files together – you just need to extract the archive the dev has provided, launch, select your files and then click on ‘Sign files’.
