*I have a pdf (which was created in latex). Is there a way to turn it back to latex?

*Another question, is there a way to add latex notes to a pdf?

  • Welcome to TeX.SE. I don't think you can recover the original LaTeX code from the pdf unless it was imbedded in it. For adding notes, see the todonotes package. Theoretically it should be possible to convert the pdf to TeX but doing that for the general case is a pretty big undertaking. – Peter Grill Jan 21 '22 at 19:00
  • Welcome to TeX! I suggest to google for "conversion pdf to latex". You may find sites like https://products.aspose.app/pdf/conversion/pdf-to-tex. Because of the difference in abstraction level (PDF: single characters positioned on pages, LaTeX: structured text with logical markup) I do not expect that you will get anything more than a document that compiles and looks similar to the pdf. PDF annotation programs usually are able to add plain text, but do not know how to handle LaTeX markup. – gernot Jan 21 '22 at 19:04
  • IMHO, these are two separate questions. Please familiarize yourself with the format of this website. Normally I would kindly ask you topmost your second question in a separate thread but it already has an answer: https://tex.stackexchange.com/questions/15314/how-can-i-superimpose-latex-tex-output-over-a-pdf-file – CampanIgnis Jan 21 '22 at 19:11
