I have a code named OfakeG (http://www.shanxitv.org/soft/OfakeG/), which is capable of converting output file of frequency analysis task of ORCA to "fake" format of Gaussian output file, but I am not sure if any PED code is compatible with this case.
]]>PED is not supported by Multiwfn, you can use other freely available codes, such as Gar2PED, VEDA, MOLVIB, etc.
