EasyEDA support import KiCAD v4.06 and greater version KiCAD files, if the KiCAD files version less then v4.06, please open them at the latest KiCAD and save as a new one, and then import them.
The KiCAD file needs to be compressed as zip file before import.

The zip file must contain:

  • Schematic and PCB
  • Libraries files and folder
  • others related files

if you compress the whole project will be better.
