Frequently asked questions
Common questions about PT Viewer.
PT Viewer works with decrypted Packet Tracer XML files. Use the included pka2xml tool to convert .pkt and .pka files to XML first. The tool supports Packet Tracer versions 5 through 9.
No. PT Viewer runs entirely in your browser. Your files are parsed locally using JavaScript — nothing is uploaded, stored, or transmitted anywhere. Your data stays on your machine.
No. PT Viewer is a standalone web app. You only need the decrypted XML file. If you have a .pkt file, the pka2xml command-line tool can decrypt it without Packet Tracer installed.
For each device, PT Viewer shows: device name, type, and model; network interfaces with IP addresses, subnet masks, MAC addresses, and link status; configured VLANs; and the full running configuration.
You can export the topology diagram as PNG or SVG images, and device data as CSV (spreadsheet-compatible) or JSON (structured data). All exports are generated client-side.
Yes, PT Viewer is completely free and open source. No accounts, no subscriptions, no limits.
