Cannot connect to 127.0.0.1 with Filezilla

I have a WordPress website installed on localhost (127.0.0.1) I am trying to connect via FTP using Filezilla to this website but all I get is: (connection rejected)

"Conectando a 127.0.0.1:21...
Estado: Falló intento de conexión con "ECONNREFUSED - Conexión rechazada por el servidor".
Error: No se pudo conectar al servidor

I included a user + password, which is the admin user of the website and I left the port field empty. Filezilla is using the port 21 by default.

FTP mode is passive.

The localhost server (an Apache server) is up and running and FTP support is enabled. When I use telnet to connect to 127.0.0.1 I receive an error message saying that the connection to the host cannot be open on port 23 (if I do not specify any port to the telnet command)

I installed the latest version of Filezilla and I am on Windows 10. I checked that I can connect to another server successfully, so the client is working.
