Data notes, charts, and lightweight experiments often begin in a notebook because it is fast to iterate. The challenge comes later, when the result has to be reviewed by people who do not work in Jupyter every day. A PDF version is easier to open, comment on, and archive.

That is the role of IPYNB Tools: it converts notebook files into PDF documents so the analysis can move from a working environment into a format suitable for review, reporting, and long-term reference.
