Frequently Asked Questions

Finn raske svar

What file formats does the TCPDump Analyzer support?

Our analyzer supports standard TCPDump (.pcap, .pcapng) files and other common packet capture formats. Files created with tools like Wireshark, tcpdump, and similar network monitoring applications are fully compatible.

Is my data secure when using the online analyzer?

Yes, all processing happens locally in your browser. We do not store your packet capture files on our servers. Your network data remains private and secure throughout the analysis process.

What is the maximum file size I can upload?

The tool supports files up to 100MB. For larger files, we recommend filtering your capture to relevant traffic before uploading or using desktop tools like Wireshark for initial processing.

Can I analyze live network traffic with this tool?

This is an offline analyzer for uploaded capture files. For live traffic analysis, you would need to capture packets using tools like tcpdump or Wireshark first, then upload the resulting file to our analyzer.
