Because xpdf-tools-win-4.04 is a local, command-line tool, it does not "call home" to any servers. It processes files entirely offline. However, note that version 4.04 is Sandboxed like a modern Microsoft Store app. If you use pdftotext on a malicious PDF, a theoretical exploit in the Xpdf rendering engine (historically low risk, but present) could execute code. For high-security environments, always scan PDFs with antivirus before processing.

: Scans a PDF and saves all embedded images (JPEGs, PNGs) as separate files.

This loop converts every PDF in the current folder into a text file in the output folder, preserving table layouts via the -layout flag.

Xpdf-tools-win-4.04 is a comprehensive suite of open-source command-line utilities designed for manipulating and managing PDF files on Windows systems. Released as part of the Xpdf project, version 4.04 offers a stable and lightweight alternative to heavy PDF software for users who prefer automation, scripting, and speed.

: High-quality conversion of PDF to PostScript for printing or further processing.

Furthermore, because these are command-line tools, you can integrate them into automated workflows. For example, a Windows Scheduled Task can run nightly to convert incoming PDF reports into searchable text for a SQL database.
