PDFx bundles multiple documents into single PDF

PDFx is an open-source extension to the PDF standard that stores multiple files inside a single valid PDF using an embedded JSON manifest. Its companion desktop application displays the documents on a Figma-style 2D canvas for easy organization while maintaining compatibility with standard PDF readers.

// ANALYSIS

A creative extension of the PDF format that resolves the frustration of managing multiple related documents without breaking standard viewer compatibility.

* Uses standard PDF metadata to embed a JSON manifest and pack files, preserving backwards compatibility.

* Offers a Figma-like horizontal and vertical scroll workspace in its desktop app for a cleaner visual layout.

* Highly useful for workflows requiring bundles of distinct documents, such as legal or real estate transactions.

* Relies on users having the companion app to extract or reconstruct the individual files.
