QUICK ANSWER
Is it possible to convert JKS to P12?
Yes - JKS converts to P12.

The main, recommended conversion (JKS is deprecated). keytool does it in one command: 'keytool -importkeystore -srckeystore in.jks -srcstoretype JKS -destkeystore out.p12 -deststoretype PKCS12'. KeyStore Explorer offers the same via 'Change Keystore Type'. p12/.pfx is then usable by OpenSSL and non-Java servers.
