PyMuPDF4LLM in Converting a complex PDF into clean Markdown with an open-source library
Scenario-level performance from current published Results.

Where PyMuPDF4LLM failed
3 of 7 graded scenarios. Open a Result to see the conversation and the evidence.
A document containing mathematical equations
PyMuPDF4LLM did not preserve the document’s equations in Markdown. It omitted all six display equations without providing math markup, an image or a placeholder.
View Result →A document with a data chart
PyMuPDF4LLM did not preserve the chart as an image in its default conversion. It retained the title but omitted the twelve plotted values. In a separate run with image embedding enabled, it emitted the chart as a PNG with its title and all twelve bars.
View Result →An ordinary digital text document
PyMuPDF4LLM fails to keep an ordinary digital text document complete and unchanged. It keeps the words, but it invents structure at page breaks: a body continuation becomes a level-3 heading with underline markup, and running headers are folded into body sentences.

Reading these Results
Published evidence and test coverage answer different questions.
Which scenarios have a Result?
A published Result is public evidence for this tool on one scenario. “No published result” does not say whether testing has taken place.
What does each Result cover?
Assessed includes Pass, Fail and Not gradable. Gradable includes Pass and Fail. Both use the pinned test count in that published Result.
Out of 12 scenarios
The summary counts each of the 12 scenarios once. A scenario fails when any of its published test cases failed. “No published Result yet” means nothing is public for that scenario; it does not say whether PyMuPDF4LLM was tested on it.
