Have a look at the docstring for variable org-export-filter-link-functions. As a very basic example, the following should work (defun my-latex-link-filter (text backend info) "Replace link to org files with pdf version." (when (org-export-derived-backend-p backend 'latex) (replace-regexp-in-string "\\.org" ".pdf" text))) (add-to-list 'org-export-filter-link-functions 'my-latex-link-filter) Note that the above example is likely too 'basic'. For example, you need to be wary of the file path if the exported PDF is going to be moved to a different location. This is one of the limitations of file links. If you have a sufficiently complex publishing requirement, you might find the org-publish module useful as it can provide a convenient way to put all your publishing configuration into a single easier to manage variable. (see org manual section on publishing).
