FTP or SFTP: What Is the Difference?

FTP or SFTP helps you move files from one computer to another. The main difference is that SFTP keeps your data safe, while FTP does not encrypt it.

Imagine you have a website and want to add new photos, pages, and videos. To do this, you need a way to send files to your website server. You may find two options: FTP and SFTP. Both can send files, but each one works in a different way.

FTP means File Transfer Protocol. It is a way to send files between computers. SFTP means SSH File Transfer Protocol. It uses a safe link to move files and protect your data.

Many people search for FTP or SFTP because they want to know which one is best. Some people need to upload website files. Others need to send work files. They may not know which method is safe.

The answer is simple. FTP is an older way to send files. SFTP adds strong safety to the process. If both are available, SFTP is often the better choice.

Pronunciation

FTP

• US: /ˌef tiː ˈpiː/
• UK: /ˌef tiː ˈpiː/

SFTP

• US: /ˌes ef tiː ˈpiː/
• UK: /ˌes ef tiː ˈpiː/

Now, let us look at the main differences.

Difference Between FTP and SFTP

1. Safety

FTP does not hide your data as it moves. SFTP uses a safe link to protect it.

Examples:

• FTP sends files without encryption.
• SFTP keeps files safe while they move.

2. Passwords

FTP may send login details without strong safety. SFTP protects these details.

Examples:

• FTP can put a password at risk.
• SFTP hides the password from others.

3. How They Work

FTP uses its own way to send files. SFTP works through SSH, which helps keep the link safe.

Examples:

• A user sends files with FTP.
• A worker sends files with SFTP.

4. Main Use

FTP can work for simple tasks. SFTP is better when files need more safety.

Examples:

• A test site may use FTP.
• A company may use SFTP for work files.

5. File Safety

FTP does not encrypt the files it sends. SFTP encrypts data as it moves.

Examples:

• FTP sends a photo without encryption.
• SFTP protects the photo during transfer.

6. Login Options

FTP often uses a name and password. SFTP can use a password or an SSH key.

Examples:

• A user logs in with an FTP password.
• A worker uses an SSH key for SFTP.

7. Ports

FTP often uses port 21. SFTP often uses port 22.

Examples:

• An FTP app may use port 21.
• An SFTP app may use port 22.

8. Business Use

Many firms choose SFTP to send private files. FTP may still work on older systems.

Examples:

• A firm sends reports with SFTP.
• An old system still uses FTP.

9. Website Files

Both methods can send files to a website server. SFTP is often the safer choice.

Examples:

• A blogger uploads pages with SFTP.
• A site owner uses FTP on an old server.

10. Best Choice

SFTP is often best when safety matters. FTP may be needed if an old system does not support SFTP.

Examples:

• A team uses SFTP to send private files.
• A user uses FTP for an old tool.

Nature and Behaviour of FTP and SFTP

FTP

FTP is an old way to send files. It can move files between a computer and a server. It is easy to use, but it does not encrypt data.

This means other people may be able to read the data if they can watch the link. For this reason, FTP is not a good choice for private files sent over an unsafe network.

SFTP

SFTP is a safe way to send files. It uses SSH to protect the link between two computers.

It can help protect files and login details. People use it to send website files, work files, and other data. It is a good choice when safety matters.

Why People Get Confused About FTP or SFTP

The names look almost the same. Both methods send files from one place to another. This can make them hard to tell apart.

The extra letter S in SFTP is linked to its secure use with SSH. But the two methods are not the same.

FTP does not encrypt the data it sends. SFTP uses an encrypted link to help keep data safe.

Comparison Table

Feature	FTP	SFTP
Full name	File Transfer Protocol	SSH File Transfer Protocol
Safety	No built-in encryption	Uses encryption
Login details	Not well protected	Protected by the secure link
Common port	21	22
Main use	Simple file transfer	Secure file transfer
Website use	Supported by some hosts	Supported by many hosts
Best for private files	No	Yes

Both methods send files, but SFTP gives better safety.

The Origin of FTP and SFTP

FTP began in the early days of computer networks. It gave people a way to send files between computers. Over time, it became a common tool for moving files.

Later, people needed better ways to protect data. SSH was made to create safe links between computers. SFTP grew from this work and became a way to send files through SSH.

Today, both methods still exist. Some old systems use FTP. Many newer systems support SFTP because it offers better safety.

British vs American English

FTP and SFTP have the same names in British and American English. Their spelling does not change.

American English:

• We use SFTP to send files.
• The server supports FTP.

British English:

• We use SFTP to send files.
