Perhaps Will fit your needs.
I did not yet have a chance to try it out personally, but I plan to in the
near future.

Under "What it can do" it says:

Translate between a variety of file formats in common use by various
programs including:

   - Amber prmtop, inpcrd, NetCDF trajectory, and NetCDF restart files
   - CHARMM PSF, coordinate, and restart files
   - Gromacs topology and GRO files
   - PDB files, supporting a wide range of dialects that technically
   violate the PDB standard
   - PDBx/mmCIF files – the new standard for the Protein Data Bank
