I am looking for some standard conversion from any hash function $f$, which has pre-image resistance, to another hash function with second preimage resistance. Is there such a standard conversion?

  • $\begingroup$ Can collision resistance be assumed too? Or only pre-image resistance? $\endgroup$

Yes. ​ I believe this is the standard conversion.
(That link is to the paper "Universal One-Way Hash Functions via Inaccessible Entropy".)
