What is a DST File in Embroidery?

A DST file (Data Stitch Tajima) is the most widely used embroidery format. Created by Tajima, it stores instructions like stitch positions, types, and color changes that embroidery machines can read directly.

This universal compatibility makes DST files the industry standard for embroidery digitizing, ensuring your design looks the same across different brands of machines.

To make a DST file, you need embroidery digitizing software. Here’s a simple step-by-step:

  1. Start with a design – Use a high-resolution image or logo.

  2. Import into digitizing software – Programs like Wilcom, Hatch, or Embird let you set stitches.

  3. Define stitch parameters – Choose stitch type, density, and sequence.

  4. Export to DST format – Save as .dst and load it onto your machine.

💡 Pro Tip: At EZ Stitch Digitizing, we create precise DST files tailored to your fabric type, avoiding common issues like thread breaks or puckering.

DST File Format and Data Structure

A DST file is more than just stitches—it’s coded machine instructions. Here’s what it includes:

  • Stitch position (X & Y coordinates)

  • Stitch type – normal, jump, or trim

  • Thread color changes

  • Machine commands – when to stop, trim, or change

This structure ensures embroidery machines replicate the design with pinpoint accuracy.

Getting your DST file onto a machine is simple:

  1. Export the DST file from your digitizing software.

  2. Save it to a USB or transfer it directly via cable.

  3. Upload it into your embroidery machine.

  4. Select the design and start stitching.

How Do Embroidery Machines Use DST Files?

Embroidery machines decode DST files line by line:

  • Read instructions for stitch placement and color changes.

  • Execute commands like trims or jumps.

  • Produce consistent results across fabrics and machines.

Modern models (Brother, Tajima, Barudan) read DST files directly via USB, making workflow seamless.

Stitch Density in DST Files

Stitch density refers to how tightly stitches are placed. DST files store this data so machines can adjust to fabric type.

  • Thicker fabrics → higher density.

  • Lighter fabrics → lower density.

✅ Best Practice: Always preview density before exporting. This prevents thread breaks, puckering, and excess strain on your machine.

If you need to convert an image or other embroidery format into DST, top choices include:

  • Ink/Stitch – free, open-source (great for beginners).

  • SewArt – versatile with multiple file format support.

  • Embird – reliable for both digitizing and conversion.

Frequently Asked Questions

1. What is a DST file used for in embroidery?
A DST file provides stitch-by-stitch instructions to embroidery machines. It ensures designs are stitched with accuracy, including thread colors, trims, and density.

2. Can I convert JPG or PNG to DST?
Yes, but not directly. You need digitizing software (like Wilcom or Embird) to convert an image into stitches and then export as DST.

3. Which software opens DST files for free?
Wilcom TrueSizer offers a free web version that allows you to view and resize DST files without altering stitch density.

4. Why is stitch density important in DST files?
Density affects durability and appearance. Too high causes puckering and breaks, too low leaves gaps. Proper density ensures balanced embroidery.
