editcap Alternative: Visual PCAP Editor Without the Command Line
editcap is powerful but requires memorizing command-line flags. A visual desktop PCAP editor lets you inspect, filter, and rewrite packets without the terminal — $19 once.
editcap is Wireshark's command-line PCAP editor. It can split captures, remove duplicates, truncate packets, and filter by time or frame number. It's powerful, scriptable, and free.
It's also entirely command-line. Every operation requires remembering the exact flag syntax. Got the flag wrong? Re-run. Forgot to quote the filter? Re-run. Made a typo in the output filename and overwrote your original capture? There's no undo.
A visual PCAP editor gives you the same capabilities with a UI you can see.
What editcap does (and what it doesn't)
editcap can:
Split captures by time, packet count, or file size
Filter packets with display filters
Remove duplicate packets
Truncate packets to a specific size
editcap can't:
Show you what you're editing before you commit
Let you undo an operation
Visually inspect individual packet fields
Provide a table view of all packets with sorting
Desktop alternative: PCAP Surgery ($19 lifetime)
PCAP Surgery is a visual desktop PCAP editor. Open a capture, see all packets in a table, apply filters visually, edit or remove packets, and export.
Visual inspection: See every packet in a sortable, filterable table. Click any packet to see its decoded fields. No tcpdump -r required.
Filtering: Apply Wireshark-compatible display filters via a text input (same syntax as editcap) or by clicking column headers to sort.
Editing: Remove specific packets. Rewrite fields. Repair checksums. All operations are visible — you see what changes before you save.
Undo: Every edit is undoable. Made a mistake? Ctrl+Z. editcap has no undo.
Price: PCAP Surgery is $19 once. editcap is free (part of Wireshark). The $19 buys you visual editing, undo, and a UI that shows you what you're doing.
