DecoNetwork uses the Wilcom embroidery engine to enable your website to perform special embroidery functions, including stitch estimation for quoting purposes, embroidery design previews, and embroidery lettering generation.
The Wilcom embroidery engine will only read files in the EMB format. If you have DST files that you wish to use on your DecoNetwork website, you will need to first convert them to EMB format before you can upload them. You can use Wilcom's TrueSizer Pro tool to open DST designs and save as EMB format. The Wilcom TrueSizer Pro tool is a paid application ($49 USD), available for download at this link: https://www.wilcom.com/products/truesizerproducts.aspx.
Note that the DST file format is not capable of retaining stitch color information, only the color change command that your machine can read. So you will need to reassign the correct thread colors before you save your file to EMB format.
