DER formatIt is a binary form of PEM. It has extension .der or .cer.

DER is typically used with Java platforms. Converter can change the type of certificate to this format – to change a private key, please use OpenSSL commands.

PKCS#7 or P7B formatIs usually stored in Base64 format and has extension .p7b or .p7c. Files in this format contain lines "-----BEGIN PKCS7-----" and "-----END PKCS7-----". This format is just for certificates, not for private key.

PKCS#7 and P7B are installed on Microsoft Windows and Java Tomcat servers.

PKCS#12 or PFX formatIs binary format storing the server certificate, intermediates certificates, and private key in one file. Usually has the extension .pfx or .p12. Typically are used on Windows machines.

When converting PFX format to PEM, in one file will be included all certificates and private key. To separate it, you need to open this file in a simple text editor, copy every single part (with BEGIN and END lines) to different files and save it as certificate.cer, CACert.cer and privatekey.key.
