I would like to convert a PDF of any size so it fits to A4/Letter. I would also like to reduce it to gray scale. This all without displaying anything.

PDFKit gives you -[PDFPage setBounds:forBox] which would easily give you A4/Letter size if that is what you specified. However, no scaling is done. A PDFPage subclass could be fairly easily written that would do the scaling though....

Look at QuartzFilters (in Quartz.framework) — this is where you can create a filter for converting to greyscale. PDFDocument allows you to pass in a QuartzFilter in the save methods (in the options dictionary) if you want to apply this Quartz Filter on saving.

So, PDF Kit can I think do what you want.
