View pdf-log-files in grafana

Hi all,
I’m learning about grafana. We have a grafana landscape and we want to view pdf-log-files from the software QF-Test (GUI Testautomatisierungs-Tool Java, Web & Windows - QF-Test). At the moment we view with loki log-files in txt-format from the software Kofax. Is it possible with loki to view the pdf-Files from the software QF-Test? Or which other possibilities exit to show pdf-log-Files in grafana?
Kind regards
