If you have ever built a website, you have probably run into the letters FTP at some point — usually right when you were trying to get your files onto a server and someone said, “Oh, just use FTP.” Cue the confused nodding.

Let me clear it up in one sentence. FTP stands for File Transfer Protocol, and it is simply a way to move files between your own computer and a web server over the internet. That’s it. It’s the digital equivalent of carrying boxes from your house (your computer) to a storage unit (the server) — except the boxes are your website’s files and the truck is your internet connection.

In this guide I’ll walk you through what FTP actually means, how it works under the hood, why it matters for web hosting, and — importantly — why in 2026 you should almost always reach for its more secure cousins instead. Don’t worry, I’ll keep the jargon to a minimum.

Key Takeaways
• FTP = File Transfer Protocol, a standard method for transferring files between a computer and a server.
• It works on a client-server model: an FTP client on your computer connects to the server, traditionally on port 21.
• In web hosting, FTP is how you upload your website files to the server so the world can see them.
• Plain FTP is not secure — it sends your password and files in plain text. Prefer SFTP (port 22) or FTPS instead.
• Popular FTP clients make connecting easy; you just need a host, username, password, and port.

What does FTP stand for and what does it actually mean?

FTP stands for File Transfer Protocol. A “protocol,” in computer terms, is just an agreed-upon set of rules for how two machines talk to each other — like a shared language. So File Transfer Protocol is the agreed-upon language computers use specifically for shuffling files back and forth.

It’s one of the oldest tricks on the internet. FTP has been around since the early 1970s, which in internet years makes it practically a fossil. Back then, the goal was simple: let one computer grab files from another, or push files onto it, without anyone having to physically hand over a tape or a disk.

When people say “FTP into the server,” they mean they’re using this protocol to log in to a remote machine and transfer files. You might upload (send files from your computer to the server) or download (pull files from the server to your computer). Both directions count as a transfer.

How does FTP work?

FTP runs on what’s called a client-server model. There are two players:

• The FTP client — software on your computer that initiates the connection (more on these below).
• The FTP server — the remote machine, usually your web host, that’s listening for connections and storing the files.

Here’s the slightly nerdy-but-interesting part: traditional FTP actually uses two separate channels to do its job.

1. The control channel (port 21) — This is where the conversation happens. Your client sends commands like “log me in,” “list the files in this folder,” or “I want to upload this.” The server replies with status messages. Think of it as the walkie-talkie line for instructions.
2. The data channel — This is the actual conveyor belt that carries the file contents. The control channel says “here it comes,” and the data channel does the heavy lifting of moving the bytes.

Splitting commands and data into two channels is a quirk of FTP’s old age, and it’s the reason FTP can sometimes be fiddly with firewalls. Which brings us neatly to one more wrinkle: active versus passive mode.

Active vs passive mode (the short version)

When it’s time to open that data channel, FTP has to decide who calls whom:

• Active mode — The *server* opens the data connection back to your client. This often trips over firewalls and routers, because your computer wasn’t expecting an incoming knock on the door.
• Passive mode — The *client* opens both connections. The server just says “meet me on this port” and waits. This plays much nicer with modern firewalls, which is why passive mode is the default in most FTP clients today.

If a connection ever hangs while listing files, flipping between active and passive mode is the classic fix. Now you know the secret handshake.

Why does FTP matter for web hosting?

Here’s where FTP gets practical. When you sign up for web hosting, you’re essentially renting space on a server. But an empty server isn’t a website — you need to get your files (HTML pages, images, stylesheets, plugins, themes) onto it.

FTP is one of the original ways to do exactly that. You connect, you drag your website folder over, and a few moments later your site is live. For years it was *the* way developers and site owners pushed their work online, and it’s still widely supported by virtually every hosting provider on the planet.

So even though newer tools exist, understanding FTP is a genuine hosting-basics skill. It’s the plumbing that connects “the files on my laptop” to “the website people see.”

FTP vs SFTP vs FTPS: what’s the difference?

This is the part I really want you to remember, so I’ll be blunt: plain FTP is not secure. It was designed in a more trusting era of the internet, long before anyone worried about hackers sniffing traffic at the coffee shop. That’s where SFTP and FTPS come in — they’re the security-upgraded versions.

Here’s the quick comparison:

Protocol	Full name	Default port	Encryption	When to use
FTP	File Transfer Protocol	21	None — plain text	Almost never; legacy systems only
SFTP	SSH File Transfer Protocol	22	Strong (over SSH)	Recommended default for most uploads
FTPS	FTP Secure (FTP over SSL/TLS)	990 (implicit) / 21 (explicit)	Strong (SSL/TLS)	When a server requires FTP-style auth but with encryption

A few things to clear up, because the names are genuinely confusing:

• SFTP is *not* just “FTP with an S.” It’s a completely different protocol that rides on top of SSH (the same secure technology used to log in to servers remotely). It uses port 22 and encrypts everything — your login and your files.
• FTPS *is* basically FTP wrapped in a layer of SSL/TLS encryption (the same family of tech that puts the padlock in your browser). It keeps the familiar FTP structure but locks the doors.

If you only take one thing from this section: when given the choice, pick SFTP. It’s secure, it’s widely supported, and it’s the modern default.

Here’s the thing nobody tells beginners. Plain FTP is a relic from a more trusting era of the internet. It sends your username, your password, and your files in cleartext — meaning anyone sitting on the network path between you and the server (a sketchy public Wi-Fi router, a compromised hop somewhere in the middle) can quite literally *read* them as they go by. No decryption required, because there was never any encryption in the first place. In 2026, that’s an unacceptable risk for almost any real workflow. So my honest advice: the “F” people obsess over in FTP isn’t the one that matters. The letter you should care about is the “S” for secure — use SFTP (over SSH, port 22) or FTPS, and treat plain old FTP the way you’d treat sending your bank password on a postcard.

What is an FTP client?

An FTP client is just the software that does the connecting and the file-dragging for you, so you don’t have to type cryptic commands into a terminal. It gives you a friendly two-panel window: your local files on one side, the server’s files on the other. You drag from left to right to upload, right to left to download.

There are plenty of free, well-loved FTP clients out there — FileZilla is probably the most famous general-purpose one, and most code editors now have FTP/SFTP plugins built in too. They all do roughly the same job: handle the connection, the login, and the transfer so you can focus on your website. Reassuringly, the good ones all support SFTP and FTPS, not just plain FTP.

How do you connect via FTP? (Step by step)

Connecting is genuinely simpler than it looks. Your hosting provider gives you a few credentials, you plug them into your FTP client, and you’re in. Here’s the routine:

1. Get your credentials from your host. Usually in your hosting control panel you’ll find a “FTP Accounts” section with the host/server address, a username, and a password. Your host will also tell you which port to use.
2. Open your FTP client (FileZilla or whatever you prefer) and find the connection or “Site Manager” screen.
3. Enter the host. This is often something like `ftp.yourdomain.com` or a server IP address your host provides.
4. Enter your username and password. These are the FTP-specific credentials from step 1 — not necessarily your main hosting login.
5. Choose the protocol and port. For a secure connection, select SFTP and use port 22 (or FTPS if that’s what your host recommends). Avoid plain FTP on port 21 unless you truly have no other option.
6. Click Connect. Once you’re in, you’ll see your server’s files on one side. Your website files usually live in a folder called `public_html` (or sometimes `www`).
7. Drag and drop to upload. Move your site files into `public_html`, wait for the transfer bar to finish, and you’re live.

That’s the whole dance. Once you’ve done it once, it takes about thirty seconds the next time.

What is FTP used for?

Beyond the obvious “putting a website online,” FTP (and its secure siblings) get used for plenty of everyday hosting tasks:

• Uploading your website files — the classic use case, especially for hand-coded sites or when you’re installing software manually.
• Bulk file transfers — moving hundreds or thousands of files at once is far smoother over FTP than uploading them one by one through a browser.
• Backups — pulling a full copy of your site’s files down to your computer for safekeeping, or restoring from one.
• Updating themes, plugins, and assets — swapping out images, editing a stylesheet, or replacing a single file quickly.
• Troubleshooting — when a site breaks and you can’t get into the admin dashboard, FTP lets you get under the hood and fix or replace the offending file directly.

FTP vs cPanel File Manager vs Git: which should I use?

FTP isn’t the only way to get files onto a server anymore. Here’s how it stacks up against the two other tools you’ll bump into:

• FTP / SFTP — Best when you’re moving lots of files, working from a desktop client, or you want a reliable, standard tool that works with any host. Great for bulk uploads and backups.
• cPanel File Manager — A file browser built right into your hosting control panel, used inside your web browser with nothing to install. Perfect for quick edits, uploading a single file, or when you’re on a computer that doesn’t have an FTP client. It’s the no-fuss option.
• Git — The developer’s choice for ongoing projects. Instead of dragging files around, you “push” code changes through version control, which tracks every revision and lets a whole team collaborate. More setup, but far more powerful for active development.

None of these is universally “best” — they’re tools for different moods. Many people happily use all three: Git for serious development, the File Manager for a quick fix, and SFTP for big uploads and backups.

Frequently asked questions about FTP

What does FTP mean in simple terms? FTP means File Transfer Protocol — a standard way to move files between your computer and a web server over the internet. In practice, it’s how you upload your website’s files so your site can go live.

Is FTP still used in 2026? Yes, FTP and especially its secure versions (SFTP and FTPS) are still widely used for uploading websites, transferring files in bulk, and creating backups. However, plain FTP is discouraged because it’s not encrypted — most people now use SFTP instead.

What port does FTP use? Plain FTP uses port 21 for its control channel. SFTP uses port 22 (it runs over SSH), and FTPS typically uses port 990 (implicit) or port 21 (explicit). When in doubt, check with your hosting provider.

Is FTP secure? No — plain FTP is not secure. It transmits your username, password, and files in plain, readable text. For anything sensitive (which is basically everything), use SFTP or FTPS, both of which encrypt your connection.

What’s the difference between FTP and SFTP? FTP transfers files without encryption on port 21. SFTP does the same job but securely, riding over the encrypted SSH protocol on port 22. SFTP isn’t simply “FTP plus an S” — it’s a different, more secure protocol that you should prefer whenever possible.
