QUICK ANSWER
Is it possible to convert CAP to PDF?
No - not a direct conversion.

The only practical path is to export a packet summary from Wireshark as plain text and then print that file to PDF using a system print dialog. This produces a PDF of the decoded packet list, not a binary-to-PDF conversion.

Why convert CAP to PDF?

PDF is a page-layout format requiring text, graphics, or structured layout. A .cap file stores timestamped binary network frames - Ethernet headers, IP addresses, TCP payloads - with no document structure. The only sensible result is printing a text export of decoded packets to PDF, not a direct format conversion.

How to convert CAP to PDF

Wireshark FREE

Open the .cap in Wireshark, go to File > Export Packet Dissections > As Plain Text, save the summary, then print the text file to PDF via the system print dialog.

About these formats

.CAP Packet Capture file (network trace) - primary meaning

A CAP file is almost always a network packet capture - a recorded snapshot of network traffic from a sniffer such as Wireshark, tcpdump, or a router. Open it with free Wireshark on Windows,…

.PDF Portable Document Format

A PDF (Portable Document Format) is a fixed-layout document that looks identical on every device - fonts, images, and layout are all embedded. Open it in any browser or the built-in viewer…

Quality & what to watch

  • The resulting PDF contains a decoded text summary of the packets, not the binary capture data - adequate for documentation or reporting purposes.
  • MuseScore and Adobe Photoshop Lightroom (listed as associated programs) cannot open network packet captures and cannot produce PDFs from them.
  • For a more structured report, paste the Wireshark text export into a word processor and format it before exporting to PDF.

Frequently asked questions

Is there any direct CAP-to-PDF converter?
No - the only sensible path is exporting a text summary from Wireshark and printing it to PDF; no tool converts the binary capture format directly to a PDF document.
Why are MuseScore and Lightroom listed as programs for this conversion?
Those are database errors - the .cap extension is shared by several unrelated formats and associated programs from other meanings leak into the network-capture entry.
How do I get a readable summary of a packet capture for documentation?
Open the .cap in Wireshark and use File > Export Packet Dissections to get a text or CSV export, which you can then save as PDF through any print dialog.
