File Transfer Protocol (FTP) for Websites: What It Is and Why It Still Matters
Why File Transfer Protocol (FTP) Still Matters in Website Management?
File Transfer Protocol (FTP) moves files between computers over a network. It uses transmission control protocol / internet protocol (TCP/IP) to transfer data reliably between your computer and web servers.
Even with newer tools, FTP remains valuable for managing websites. It handles large files well, works with most hosting environments, and offers flexibility that developers need.
Secure versions like File Transfer Protocol Secure (FTPS) and Secure File Transfer Protocol (SFTP) address modern security concerns while keeping FTP’s core strengths intact.
A Brief History of File Transfer Protocol (FTP)
Abhay Bhushan created FTP in 1971, making it one of the internet’s oldest protocols. It originally ran on network control protocol (NCP), which came before today’s TCP/IP system.
The protocol improved through updates like RFC 114, RFC 765, and RFC 959. These changes added better security, functionality, and cross-system compatibility.
How File Transfer Protocol (FTP) Works: The Client-Server Model
FTP uses a client-server setup. Your computer acts as the client, requesting files. The hosting machine serves as the server, responding to your requests.
Two channels handle the work: a command channel sends instructions like login requests, while a data channel transfers the actual files. This separation makes communication efficient.
File Transfer Protocol (FTP) Commands and File Operations
FTP includes built-in commands for remote file control.
- GET downloads files from the server.
- PUT uploads files to the server.
- LIST shows directory contents.
- DELETE and RENAME help you manage files.
- USER and PASS handle login credentials.
Servers respond with codes like 200 OK for success or 530 Not Logged In for failed logins. These codes help you understand what’s happening during your session.
File Transfer Protocol (FTP) Connection Modes: Active versus Passive
FTP offers two connection modes that determine how the data channel opens.
In active mode, the client tells the server where to connect. Firewalls often block this because the server initiates the connection back to your computer.
Passive mode solves this problem. The server tells the client which port to use, letting the client start both connections. This works better with firewalls and is more common today.
How to Use File Transfer Protocol (FTP) to Manage Your Website?
You can connect to FTP servers in several ways, depending on your needs and technical comfort.
Command line tools like Windows CMD or macOS Terminal give direct access but require knowing specific commands. Developers who value speed often prefer this method.
Web browsers can access FTP by typing ftp:// before the server address. However, Chrome and Firefox have stopped supporting this due to security concerns.
FTP clients like FileZilla, Cyberduck, or WinSCP work best for most users. They offer drag-and-drop features, file queuing, and better error handling.
Some web development tools and hosting control panels like cPanel include built-in FTP access for convenience.
Web developers often rely on these tools. Mainly used for the literal name which is transferring files from or to a website.
Types of File Transfer Protocol (FTP)
FTP comes in variations with different security levels and uses.
Plain FTP is the standard version without encryption. It uses port 21 and most web hosts support it.
Anonymous FTP lets users log in without credentials. It’s often used for public file sharing.
Password-Protected FTP requires login credentials but still lacks encryption unless you add another security layer.
File Transfer Protocol Secure (FTPS) adds secure sockets layer (SSL) or transport layer security (TLS) encryption. It can be implicit, with default encryption, or explicit, starting unencrypted then upgrading.
File Transfer Protocol Explicit SSL or TLS (FTPES) works like FTPS but explicitly starts encryption after connecting.
Secure File Transfer Protocol (SFTP) uses secure shell (SSH) for secure file transfer and authentication. It’s technically not FTP but is widely used for security-sensitive work.
Security Considerations with File Transfer Protocol (FTP)
Standard FTP sends data in plain text, including your username and password. This leaves sensitive information vulnerable to interception.
Anyone monitoring the network could capture your credentials or files. For businesses handling client or legal data, this creates serious risks.
Using secure protocols like FTPS, FTPES, or SFTP reduces this risk. Configure firewalls, access controls, and monitoring systems to keep your implementation safe.
Pros and Cons of Using File Transfer Protocol (FTP)
Advantages
FTP handles large files and batches efficiently. It can resume interrupted transfers, which saves time. The protocol works with many operating systems and hosting platforms.
Web developers and SEO teams focus on user experience and page speed. FTP helps them move files faster. Going more into CDN but better asset delivery can lead to faster page loads.
Disadvantages
Default FTP lacks encryption, creating security risks. Setup and secure configuration can be complex. Firewalls or network address translation (NAT) may cause issues without passive mode enabled.
File Transfer Protocol (FTP) versus Other File Transfer Protocols
Modern protocols offer similar functionality with added security or features.
Secure File Transfer Protocol (SFTP) uses secure shell (SSH) to secure connections. It encrypts both data and credentials, making it preferred in compliance-heavy industries.
File Transfer Protocol Secure (FTPS) builds on FTP by adding SSL or TLS encryption. It keeps FTP’s structure while securing the connection.
Hypertext Transfer Protocol (HTTP), designed for web browsing, isn’t ideal for large file transfers. Hypertext Transfer Protocol Secure (HTTPS) adds encryption, making it better for secure downloads.
Managed File Transfer (MFT) provides enterprise-level solutions with automation, monitoring, and audit trails. This works well for regulated environments.
Use Cases for File Transfer Protocol (FTP) in Today’s Digital Workflows
FTP remains essential in web management and information technology (IT) operations.
For example, agencies offering SEO services often use FTP to upload optimized content. They update metadata and apply technical changes directly on the site’s backend.
Developers use it to upload hypertext markup language (HTML), cascading style sheets (CSS), and images to web servers. It helps deploy new code or update website assets.
FTP supports scheduled tasks like backup scripts or file syncing between systems.
In enterprise settings, FTP moves large files such as media content, software builds, or databases across internal networks.

Is FTP secure, and should I use FTP for my website?
Standard FTP isn’t secure. It sends data in plaintext, making it vulnerable. For secure transfers, use SFTP or FTPS, especially when handling sensitive information.
How do active and passive modes work in FTP?
Active mode has the client tell the server where to connect, but firewalls often block this. Passive mode lets the client connect to a server-specified port, working better with firewalls.
How can I connect to an FTP server?
You can use command-line tools, FTP clients like FileZilla, or browsers (though modern browsers often block this). FTP clients provide the most user-friendly experience.
How do I set up a File Transfer Protocol (FTP) server for my website?
Download FileZilla or Cyberduck to connect. Configure users and permissions, and ensure port 21 is accessible. Nowadays port 22 is more often as it’s secured (SFTP). Always secure your setup with encryption and strong authentication for sensitive data.
Why is FTP less used today and what are modern alternatives?
FTP lacks encryption, making it unsuitable for secure environments. Modern alternatives like SFTP, FTPS, HTTPS, and MFT offer better security, automation, and compliance.
