Is my pcap file uploaded to any server?

No, never. Your packet capture file is parsed entirely in your browser using JavaScript. No network data, IP addresses, or packet contents are transmitted anywhere.

We support standard .pcap files (libpcap format), .pcapng (next generation), and .cap files. These are the formats used by Wireshark, tcpdump, and most packet capture tools.
