DST to DOTX Converter

DST (Tajima) is a machine embroidery file format created by Tajima Industries, one of the world's leading manufacturers of commercial embroidery equipment. The format encodes stitch data as a sequence of relative coordinate movements, with each stitch record containing a horizontal offset, vertical offset, and a command flag indicating the stitch type — normal stitch, jump (move without stitching), color change, or stop. DST files use a compact binary encoding where each stitch occupies three bytes, making the format efficient for storing complex multi-color designs with tens of thousands of stitches. The coordinate system uses 0.1 mm increments with a maximum single-stitch length of 12.1 mm in any direction. DST has become the de facto standard in the commercial embroidery industry — virtually every embroidery machine from any manufacturer can read DST files, making it the most widely supported embroidery format in existence. One advantage is universal machine compatibility: a DST file will run reliably on Tajima, Barudan, SWF, Brother, and Melco machines alike, eliminating format conversion concerns. The minimal file structure is another strength — files are compact, load instantly even on older machine controllers with limited memory, and their simplicity makes them resistant to corruption during transfer. While DST lacks embedded metadata like thread color names and design previews, this limitation is offset by the format's unmatched portability across the global embroidery industry.
