What is a DST file?
A DST file (Tajima DST) is the most common embroidery machine format. It stores the stitch coordinates, jump stitches, trims and color-change commands that drive a commercial embroidery machine. Because it only stores stitches — not the original artwork — you need a DST viewer to actually see what the design looks like.
Our online DST viewer reads the file directly in your browser and reconstructs the design with a realistic, true-to-thread preview. You can inspect the stitch path, recolor threads, switch the simulated fabric, and read the design size and stitch count before sending it to your machine — no desktop digitizing software required.
