A Python CLI tool that converts CNKI's proprietary CAJ document files into PDFs while preserving selectable text and outline information. It reverse-engineers the CAJ/HN binary formats and supports only a subset of files, with conversion success varying by sample.
Use cases
- convert caj files from cnki to pdf
- read cnki theses on linux or mac without cajviewer
- extract outline/bookmarks from a caj file into a pdf
- batch convert academic papers downloaded from cnki
- make caj documents searchable and text-selectable
When to choose
- you have CAJ-format (not HN-format) files from CNKI and need real PDFs with text and outlines
- you work on non-Windows platforms where CAJViewer is unavailable
- you need to add outlines to a PDF printed via CAJViewer
When to avoid
- your file is HN format or reports 'Unknown file type'
- you need a guaranteed, user-friendly converter for all CAJ files
- you want a GUI tool rather than a command-line workflow
