Convert PDF to DST

Converting Adobe Portable Document Format to Tajima Embroidery Format (.pdf to .dst conversion) should be possible, if you want to create embroidery designs directly from PDF documents. The document should, however, contain graphics, ideally vector graphics.

Try using software, such as CorelDRAW, which is capable of exporting its projects to embroidery design file types.

Should you not have access to CorelDRAW, try exporting your graphics to .svg format (Scalable Vector Graphics) first. You will then be left with far more choices to convert your graphics to Tajima embroidery design.
