Depends a bit what you're after.
AFAIK, there aren't any - legal - downloads for Jepps or equivalent. However, approach plates, SIDs & STARS and airport diagrams can be found. In Spain, AENA (

In the US, there's

While it says 'current' on there, I've got my doubts, looking at some of the dates.
For France you can try this:
