Export multiple artboards in Adobe Illustrator to png, or pdf

Export multiple Adobe Illustrator artboards to png, jpg, pdf

This is a reference to Matthew Ericson's article Export Illustrator Layers and/or Artboards as PNGs and PDFs in case something happens to happen to the article, and if I just forget where to find the exporter online.

Usage

  • Drop MultiExporter.js into /Applications/Adobe\ Illustrator\ CS6/Presets.localized/en_GB/Scripts
  • Restart Illustrator
  • Name your artboards / layers anything but the default names (script will ignore un-renamed artboards / layers)
  • Run the script by going to “File > Scripts > MultiExporter”
  • Profit!
