FTP and SFTP: Uploading Files to Your Server
March 2, 2026
What is FTP?
FTP (File Transfer Protocol) is a method for uploading files from your computer to your server.
FTP vs SFTP
FTP
The standard protocol, but data is sent unencrypted.
SFTP
Secure FTP encrypts all data. Always use SFTP when possible.
FTP Client Software
FileZilla, Cyberduck and WinSCP are popular free FTP clients.
Connecting via FTP
You'll need: a server address, username, password and port number (usually 21 for FTP, 22 for SFTP).
FTP Alternatives
Your control panel often has a built-in file manager. Handy for small changes.
