Download PuTTY
Current stable release
No-cost setup · Windows MSI · Linux and macOS packages
PuTTY carries no licensing fee. On Windows, pick the 64-bit or 32-bit MSI so putty.exe, puttygen.exe, pscp.exe, psftp.exe, plink.exe, and pageant.exe land in one pass. Filenames usually echo your CPU architecture (most modern PCs take the 64-bit installer). After installation, follow the Step-by-step guide on this site for the first launch and SSH login.
Quick start |
Shortest path for most readers. Grab the official Windows installer (64-bit matches most current PCs), execute the MSI, then start PuTTY from the Start menu. Spin up keys in PuTTYgen whenever the server demands public-key login. PuTTY site home |
Windows |
MSI together with portable zip. Select the build aligned with your processor architecture. After setup, store a session with host, port 22, and SSH. For Telnet-only work, puttytel.exe stays in the package. If policy demands it, confirm the publisher and checksum bundled with your download before executing the installer. Capability highlights |
macOS & Linux |
Repositories and ports. On Linux, install putty and commonly putty-tools for puttygen. On macOS, Homebrew, MacPorts, or comparable channels publish the same family—use whatever your administrator authorizes. PuTTYgen across platforms · Step-by-step guide |
