StitchPilot.aiGuide · DST file viewer
DST files are the standard embroidery format for commercial machines — but they can't be opened in image viewers or standard design software. StitchPilot.ai lets you view DST stitch layouts, export PNG previews, and convert to other formats directly in the browser, with no software installation required.
Steps to open a DST file
DST files typically have a .dst extension. They may come from a digitizer, embroidery supplier, design library, or production partner. DST is a stitch-only format — it contains no color information, so previews will show stitch paths without specific thread colors.
Go to the Embroidery Viewer or Embroidery to Image tool. Drag and drop your DST file or use the file selector. StitchPilot.ai reads the stitch data and renders the design in the browser — no account required for basic viewing.
Inspect the rendered stitch layout for overall design shape, fill coverage, color stop positions, and any obvious issues (missing fills, stray stitches, overlapping regions). This is your quality check before using the file for production or conversion.
Download a PNG preview image for sharing or archiving, or convert the DST to another format (PES, JEF, VP3) if needed for your machine. When converting from DST, you will need to assign thread colors manually in the output file.
What is DST?
DST (Data Stitch Tajima) was developed by Tajima, a major commercial embroidery machine manufacturer. It stores stitch movements only — no color data, no thread brand references. Despite its age and simplicity, DST remains the most widely accepted format for commercial embroidery shops worldwide.
What to check before production
Before using a DST file for production, verify these key elements. A few minutes of review can prevent costly mistakes and remake orders. The stitch preview in StitchPilot.ai helps you check all of these before the file goes to a machine.
DST files — common questions
Upload the DST file to StitchPilot.ai's Embroidery Viewer or Embroidery to Image tool. Both work in the browser without installing any software. The viewer shows the stitch layout interactively; the image export creates a PNG you can share or save.

DST is a stitch-only format with no embedded color data. Color changes appear as color stops in the sequence, but the specific thread colors must be assigned manually by the machine operator or in embroidery software.
