Q: key to pdf : links lost

Hi,

I have the 6.6.1 version of Keynote and I am using a Macbook Pro within El Capitan.

When I make a presentation with Keynote, I need to send in a .pdf format.

My problem : when I print the document with the pdf converter provided by Apple, I lose all the hyperlinks (both internal and external).

Is there a possibility to convert a .key to a .pdf keeping those links ?

If this is not possible with the Apple tool "print to pdf", do you know a free virtual printer to install on my computer which can convert the .key document to .pdf keeping the links ?

Many thanks !
