I want to create a .crt file which is going to trust https when I use fiddler on my phone. I find few site but they generate .cert and not .crt.

But this format isn't working. I need a .crt that's look like this
Thanks
That's pem(base64) encoded certificate and all you need is der(binary) encoded. You can use openssl to convert it:
openssl x509 -outform der -in <yourcert.crt> -out <out.crt>
No matter with extension. You can rename with .cer .der .pem or .crt as you need.
