PDFSyntax: A Dependency-Free Python PDF Visualization Tool

PDFSyntax is a self-contained Python library, requiring no dependencies, that visualizes the internal structure of PDF files as interactive HTML. It parses, decompresses, and pretty-prints PDF data, adding hyperlinks and indices to enable logical navigation through the PDF, including object traversal and revision tracking. A simple command-line operation generates static HTML viewable directly in a browser without requiring JavaScript. Features include reverse indexing, page indexing, a thumbnail map, object stream extraction, stream decompression, and syntax highlighting. Encrypted files are not yet supported.
