PDFx – Extract Metadata and URLs from PDFs, and Download Referenced PDFs

In plain words

PDFx is a tool that extracts metadata and URLs from PDF documents and downloads all referenced PDFs automatically. Users can process a PDF file to identify links and references, optionally outputting all references rather than just PDF files. The tool includes command-line flags for specifying download directories, making it useful for researchers and anyone needing to batch-download papers or documents linked within a PDF.

Lets examine this paper: https://weakdh.org/imperfect-forward-secrecy.pdf You can use the -v flag to output all references instead of just the PDFs. Download all referenced pdfs with -d (for download-pdfs ) to the specified directory (eg. /tmp/ ): You can find the code here on Github: https://github.com/metachris/pdfx .
