TFTP Server

Lightweight, standards-compliant TFTP server for Windows, macOS and Linux

SoftPerfect TFTP Server is a standards-compliant TFTP server implementing the full RFC 1350 specification with modern extensions for improved performance. It comes in three deployment options: a GUI application with live transfer monitoring, a lightweight console version for scripting and headless servers, and a Windows service for unattended 24/7 operation.

The server supports all common TFTP options including block size negotiation (RFC 2348), transfer size (RFC 2349), and window size (RFC 7440) for faster transfers. It handles files larger than 4GB through block number wrapping and includes security features like IP filtering and path traversal protection. Best of all, it is completely free to use with no limitations.

Where TFTP Server is useful

Network device firmware updates — Routers, switches, IP phones, and embedded devices often use TFTP to receive firmware updates and configuration files.
PXE and network booting — Boot diskless workstations, thin clients, or set up network installations by serving boot images via TFTP.
VoIP and IP phone provisioning — Automatically configure IP phones and VoIP devices by serving configuration files on demand.
Embedded systems development — Transfer firmware, configuration files, and debug data between development workstations and target devices.
Network equipment configuration backup — Receive and store configuration backups from managed switches, routers, and firewalls.
Lab and testing environments — Quick file transfers in isolated networks without complex setup.
