TigerVNC (vncviewer) is a VNC client for connecting to remote desktops. It displays the graphical desktop of a remote VNC server and allows interaction via keyboard and mouse.
The viewer supports multiple encodings optimized for different network conditions: Tight encoding with JPEG compression for low bandwidth, and raw or hextile for local networks. Automatic encoding selection adapts to connection quality.
Security features include TLS encryption and various authentication methods. The -via option provides SSH tunneling for secure connections through untrusted networks.
TigerVNC can also act as a reverse-connection client using -listen mode, where the server initiates the connection to the viewer.

TigerVNC is a fork of TightVNC, focused on performance and security improvements. It originated from the VNC (Virtual Network Computing) technology developed at Olivetti Research Laboratory in the late 1990s. TigerVNC is widely used in enterprise environments and Linux distributions.
