How to Open InDesign CS6 in CS3

To be able to open an Adobe InDesign CS6 file in CS3 there are a few steps you need to take

  • First you will need to open the file in the CS6 version of InDesign (or CC) and save the file as an IDML file, using the Save As or Export options from the file menu.
  • Then open this IDML file in InDesign CS4 and export it to an .inx file. This will convert the file into a format that CS3 can open.

We do offer a InDesign down-saving service if you don’t have Adobe InDesign CC or CS6 and CS4, to help open the file into the CS3 version.
