If you have a self-signed certificate generated by makecert.exe on a Windows machine, you will get two files: cert.pvk and cert.cer. These can be converted to a pfx using pvk2pfx

pvk2pfx is found in the same location as makecert (e.g. C:\Program Files (x86)\Windows Kits\10\bin\x86 or similar)

pvk2pfx -pvk cert.pvk -spc cert.cer -pfx cert.pfx
