Best TFTP Servers for Windows, Linux, and macOS

If you need a TFTP server for firmware images, configuration backups, PXE boot files, or lab work, the best choice depends on your operating system and whether you want a standalone service or extra DHCP/PXE features. On Windows, SolarWinds TFTP Server is the easiest free pick, while Tftpd64 suits labs. On Linux, tftpd-hpa is a dependable default, and atftpd adds advanced TFTP extensions. On macOS, tftp-hpa through MacPorts is the clearest standalone option.

Best TFTP servers at a glance

What TFTP does, and why you should isolate it

TFTP is intentionally minimal. RFC 1350 defines it as a simple UDP-based file-transfer protocol with read and write requests but no directory listing or user authentication. The initial request uses UDP port 69; the transfer then uses negotiated transfer identifiers and UDP ports.

That simplicity works well for boot loaders, switches, routers, firewalls, phones, and embedded devices, but not for sensitive transfers over untrusted networks. Microsoft warns that TFTP has no authentication or encryption and no longer provides a Windows TFTP server service. Use it only on a trusted management VLAN, lab network, or restricted segment. For secure general-purpose transfers, use SFTP or SCP.

Best TFTP servers for Windows

SolarWinds TFTP Server: best simple free option

SolarWinds TFTP Server is still offered as a free Windows tool. Its product page highlights concurrent transfers, authorization by IP address or range, and operation as a Windows service. It is a practical choice for firmware and configuration files without a larger network-management suite.

Tftpd64 / Tftpd32: best all-in-one lab tool

Tftpd64 is an open-source Windows utility from Philippe Jounin that bundles TFTP with DHCP, DNS, SNTP, and Syslog. Current releases include signed Windows binaries, and version 4.74 added support for files larger than 4 GB. It is especially useful for provisioning networks and PXE labs where several lightweight services are convenient in one application.

haneWIN TFTP Server: best for granular access control

haneWIN TFTP Server is shareware with 32-bit and native 64-bit Windows builds. The vendor lists Windows 11 support, RFC 2347-2349 extensions, multicast, configurable UDP data-port ranges, and access controls based on operation, client IP, and server directory. It fits environments that need tighter upload and download rules.

Best TFTP servers for Linux

tftpd-hpa: best general-purpose Linux daemon

tftpd-hpa remains packaged in Debian stable and is a conventional choice for PXE and device-management workflows. It is small and easy to run with a restricted TFTP root. On Debian-derived systems, use the distribution package and its current service defaults rather than copying old configuration paths from unrelated releases.

atftpd: best for advanced TFTP features

atftpd is also available in current Debian releases. Debian describes it as a multithreaded server supporting the core TFTP RFC plus option negotiation, multicast, and the RFC 7440 windowsize extension. It is a strong fit for specialized boot and deployment environments.

dnsmasq: best for PXE-oriented read-only serving

dnsmasq can provide TFTP alongside DHCP/DNS. Its TFTP server is deliberately limited to read-only boot-file serving and supports options including --enable-tftp, --tftp-root, and a configurable connection limit. It is ideal for PXE, but not when devices must upload configuration backups.

Best TFTP servers for macOS

tftp-hpa via MacPorts: best standalone choice

MacPorts packages tftp-hpa for modern macOS and provides a server variant with launchd startup support. MacPorts documents a restricted root directory and an optional upload-enabled variant. This is a more maintainable choice than relying on old macOS TFTP tutorials whose launchd instructions may not match your current release.

dnsmasq via Homebrew: best when you also need DHCP/DNS

Homebrew currently ships dnsmasq for Apple Silicon and supported Intel macOS versions. Pair it with the documented dnsmasq TFTP options for a lightweight PXE or boot-file server. Its built-in TFTP service is read-only.

Which TFTP server should you choose?

• SolarWinds: simplest Windows service with a GUI and IP restrictions.
• Tftpd64: Windows labs that also need DHCP, Syslog, or related services.
• haneWIN: per-client and per-directory controls.
• tftpd-hpa: straightforward Linux or macOS daemon.
• atftpd: multicast or advanced TFTP extensions.
• dnsmasq: read-only PXE boot files with DHCP/DNS integration.

Whichever server you use, keep TFTP off the public Internet, restrict the server root, limit clients at the firewall or server configuration, and enable write access only when the workflow requires it.
