Original GitHub issue: https://github.com/Mintplex-Labs/anything-llm/issues/592

What would you like to see?

The PDF when uploaded has some issue:

  1. chunks are more compared to txt - probably due to the formatting of the pdf file - the /n are more an lines are not continuous making the file large and making more cunks.
  2. the superscripts/ headers and footers of pdfs in the pdfs are also included causing lot of confusion to the llm - if I ask like "tell me about section 2" -I know a lot of cleaning has to be done before uploading a file - but I can't expect all managers to do that who will only finally complain that the LLM is not good.

I have been working around this by first converting the PDF to text/markdown which seems to help.
