FTP & SFTP Client With No Download — Works in Your Browser

Classic FTP software is a desktop download: you install it, patch it, and manage it like any other program. If you'd rather not — or your machine won't let you — FilePort Pro does the whole job in your browser. Nothing to download, nothing to install, and no plugin or extension to add. Open the page and connect to your FTP or SFTP server.

Connect Now — no download, no install

Runs entirely in the browser

FilePort Pro is a real web FTP and SFTP client: the connection logic runs in the page, so your browser does the work that a desktop program would. There's no installer, no executable, no plugin, and no browser extension. If you can open a web page, you can reach your server — on Windows, macOS, Linux, ChromeOS, or a tablet.

Because there's nothing to install, it works the same way on a shared library computer, a school machine, or your own laptop. You don't have to ask an admin to approve software, and there's no version to keep up to date — the app you use is the current one.

What you can do once connected

This page's connection panel lives on the web FTP client and the web SFTP client, right here in your browser:

• Connect to FTP or SFTP — enter your host, port, username, and password and click Connect.
• Browse your server — navigate folders with breadcrumb navigation, just like a file manager.
• Upload files — upload single files or several at once, or drag and drop them from your computer.
• Download files and folders — download individual files or a whole folder as a ZIP archive.
• Manage web-host files — upload themes, plugins, and media to your hosting account's file structure without the hosting company's web-based file manager.

Credentials you need from your host

Before you connect, your web host or server admin gives you the details you'll type into the panel:

• Host — the server address, for example ftp.example.com, sftp.example.com, or an IP address.
• Username and password — the FTP/SFTP account login from your host's control panel (for example cPanel, Plesk, or your host's own panel).
• Port — usually 21 for FTP and 22 for SFTP. Use the exact port your host lists; some hosts run SFTP on a custom port.
• SFTP host-key fingerprint (optional) — FilePort Pro remembers the server's SSH host key the first time you connect and warns you if it changes later, so you can confirm you're reaching the right server. You don't need the fingerprint in advance — just be deliberate about accepting it.

Got these ready? Open the connection panel and connect. Not sure where to find them? See the matching cPanel or WordPress guide, or check your host's help pages.

Limitations to be honest about

FilePort Pro is a hosted, browser-based client, and that comes with a few honest limits you should know before you rely on it:

• It needs a modern browser with JavaScript. The app is a web page, so it needs a current browser with JavaScript enabled. Very old browsers, or browsers with scripting disabled, won't run it.
• Managed networks can still block you. A corporate or school network may block FTP/SFTP ports, run an outbound proxy, or use an allowlisted web filter that the server-side relay cannot bypass. If the connection times out or is refused on a managed machine, the block is almost always the network's policy, not your credentials.
• The relay can't reach your local LAN. Because the connection passes through a cloud-based relay, FilePort Pro can only connect to hosts that are publicly reachable on the internet. It cannot reach an FTP or SFTP server running on another device on your home or office network.
• Large transfers depend on your connection. Speeds and reliability are bounded by your internet connection. Very large uploads or downloads still move over your network, so a slow link means a slow transfer.

Common connection problems and fixes

• "Connection refused" — nothing is answering on that port. Confirm the host and port are correct, the server is running, and your host's firewall allows FTP (21) or SFTP (22) from outside.
• "Connection timed out" — traffic is being dropped, usually by a firewall or a managed network's outbound filter. On a corporate or school network, check whether the network allows outbound FTP/SFTP; if it doesn't, you can't reach the server from that network no matter what you enter.
• Wrong port — FTP uses port 21, SFTP uses port 22 (often a custom port with some hosts). Selecting FTP when the server only offers SFTP (or vice-versa) will fail. Use the exact protocol and port your host lists.
• "Authentication failed" — the username or password is wrong, or the account isn't enabled for the protocol you chose. Re-check the credentials in your host's control panel.
• "Host key changed" / fingerprint mismatch — the server's SSH host key differs from what you accepted before, which can happen after the server is rebuilt or if you're reaching a different machine. Confirm you're connecting to the right host before accepting the new fingerprint deliberately.

Is a no-download FTP client secure?

Because FilePort Pro relays your connection, your credentials pass through our server to reach yours — never "credentials never leave your browser." They're handled with a few careful guarantees: they're held in memory only for the active session, they're never stored or logged, and the session ends when you disconnect or after about 15 minutes of inactivity. The app is served over HTTPS, and SFTP runs inside an encrypted SSH session with host-key verification. Plain FTP sends your password unencrypted by protocol design, so the app warns you and recommends SFTP whenever your host offers it. For the full, code-verified details, see our security page.

Frequently asked questions

Is there an FTP client that requires no download?

Yes. FilePort Pro is a web-based FTP and SFTP client: it runs entirely in your browser, with nothing to download and nothing to install. There's no desktop program, no plugin, and no browser extension. Open the page, enter your server's address and login, and you can browse, upload, and download files the same way you would with installed software.

Do I need to install anything or add a plugin to use it?

No. Because FilePort Pro is a web app, it needs only a modern browser with JavaScript enabled — the browser you almost certainly already have. You don't install a program, enable an extension, or add a plugin. If you can open a web page, you can connect to FTP or SFTP.

Why can't FilePort Pro reach a server on my local network?

FilePort Pro relays your connection through a cloud server, so it can only reach hosts that are publicly reachable on the internet — not an FTP or SFTP server sitting on your home or office LAN. If you need to transfer to a device on your local network, use a tool that runs on that machine instead.

Can a managed or school network still block FTP?

Possibly. A managed device or network may restrict outbound traffic — such as blocked ports, an outbound proxy, or an allowlisted web filter — that the server-side relay cannot bypass. If the connection times out or is refused, that is usually your organization's or network's policy, not a problem with your credentials.
