There are two websites that tell you how to convert from one format to another. Some conversions are fairly easy while others take a bit of time but are still fairly easy.
Check out Ducky's Designs and Digital Designs by Stephanie for instructions.
Hope this helps!
I have been asked about converting my files. Currently my files only are available in JPG, MTC and SVG formats. I am considering making them in more formats, but at that point, I will have to limit the lenght of time that the files are free - after the free period, they will be available for sale.
I am thinking that I will make the files available in:
AI
This is an illustrator file. KNK Studio can open this file type. Inkscape can open Illustrator files that are saved with PDF compatibility.
GSD
This is a file type that works with the Robo Master program.
WPC
This file type works with the WinPC/SignLab programs. WPC 14 in order to make them accessible to the most users with Funtime or Scrap Savvy Funtime etc.
PDF
If you would like to use them for a paper piecing and do not own a digital cutter yet.
Since this is a time intensive project, I don't expect all the files to be converted until after the first of next year.
