DST File Viewer
Open and preview Tajima DST files free — stitch count, size and colors.
Quick answer: A DST file is Tajima's commercial machine-embroidery format: it stores raw needle movements, not an image, so ordinary software can't open it. You can view a DST free in your browser with the tool below — it shows the stitch count, design size, color changes and a visual stitch preview, with no upload and no software install.
Open any Tajima .DST embroidery file directly in your browser to see its real stitch count, dimensions, color changes and a visual preview of the stitch paths. The file is parsed locally — it is never uploaded to a server.
DST is the industry-standard commercial embroidery format. Because it stores raw needle movements with no image preview inside, you normally need embroidery software just to see what a file contains — this viewer replaces that for quick checks.
How it works
- Drop the file — it is parsed byte-by-byte in your browser and never uploaded.
- See the stitch count, design size, color changes, and jump/trim counts read from the actual stitch data.
- Preview the stitch paths on a zoomable canvas, color block by color block, and export the preview as a PNG.
Good to know
- Stitch files don't store thread colors (DST) or store only palette hints (PES) — preview colors are for separating color blocks, not thread matching.
- The preview draws stitch paths, not simulated thread — actual sewn texture, density and pull depend on fabric and stabilizer.
Frequently asked questions
Is my design file uploaded anywhere?
No. The .DST file is decoded entirely inside your browser. For a commercial design that matters — your file never touches our servers.
Why doesn't the preview show my thread colors?
The DST format physically cannot store thread colors — it records only needle movements and color-change stops. The machine operator assigns real threads at sew-out. Our preview gives each color block a distinct display color so you can see the separation.
What does the stitch count tell me?
Stitch count drives embroidery pricing and run time. Most left-chest logos run 4,000–10,000 stitches; jacket backs can exceed 30,000. This viewer reads the true count from the stitch data, including jumps and trims.
Can I edit or resize the DST here?
No — and be careful with tools that claim to. DST files scale poorly because stitch densities don't adjust automatically. Resizing more than ~10% usually needs re-digitizing from the original artwork.
