Supports HAR, WPT json, Chrome traces, Chrome netlogs, tcpdump (.cap.gz), rumcap
(.rcap), and qlog files. Chrome traces and .rcap sources also open in
the embedded Perfetto and DevTools viewers; qlog inputs can open in qvis when installed.

...or Drag & Drop anywhere to load your files, or input them locally
For tcpdump with TLS Decryption, select or drop both the .cap.gz and
your SSL keylog file together. For qlog, drop all of a page load's per-connection
.qlog/.sqlog files together to see one merged waterfall and qvis session.
