pcb-rnd can load and save gEDA PCB,  KicadProtel Autotrax,  DSN and Eagle
layouts, along with their netlists, but exporting to Kicad would be a
retrograde conversion, in that Kicad has more limited support for arcs on
copper,  padstacks, slots and negative layer types than pcb-rnd.

If your design lacks these features,  the conversion should be closer to
lossless,  but Kicad struggles with things as simple as placing isolated
stitching vias, due to its insistance on allocating a net to all objects,
not breaking design backward compatability with Kicad dot revisions, and
using different track widths on the same net.

pcb-rnd can also load Eagle,  Kicad and BXL footprint libraries, allowing
you to take advantage of the Kicad ecosystem but remaining in a more
familiar environment.

eeschema differs a lot to gschem/lepton-schematic, in that symbols are
defined in the layout with associated rotation matrices,  making conversion
tedious.

gEDA PCB and pcb-rnd are netlist agnostic,  in that the source of the
netlist is up to the user, and a user can even start designing a pcb with
no schematic at all.   pcb-rnd can even import eeschema and various other
netlist formats such as from tinycad and Eagle.

Kicad,  on the other hand,  has pcbnew pretty tightly integrated with
eeschema,  and this may not suit everyone with particular workflow needs.

Regards,

Erich
