Is there a free command line program for converting PDF files to SVG? Once upon a time I used Corel Draw to edit vector graphics. Now I'm looking at using Sketch. I previously converted all my old CDR files to PDF but Sketch doesn't seem to like to open PDFs containing vector graphics. Is there a free command-line program I can use to convert PDF to SVG?
Turns out Inkscape has a command line mode. I added this to .bash_profile:

alias inkscape="/Applications/Inkscape.app/Contents/Resources/bin/inkscape"


and now this command converts from PDF to SVG:

inkscape Logo.pdf --export-plain-svg=Logo.svg


Unfortunately, the current version of Sketch has very rudimentary SVG import capabilities and can't correctly read any of the files I've made even though they display fine in Opera and OmniWeb. The company says future versions will do better.
