What does DST stand for in embroidery?

DST stands for Data Stitch Tajima. It is the embroidery file format created by Tajima Industries — the world's largest commercial embroidery machine manufacturer — and has been the industry standard since the 1980s.

What file format does my embroidery machine use?

Commercial machines (Tajima, Barudan, SWF, ZSK, Happy) use DST. Brother machines use PES. Janome uses JEF. Husqvarna Viking and Pfaff use VP3. Most machines also accept DST as a secondary format. When in doubt, request DST — it works on nearly every machine.

Why does my DST file show only one color?

No. Illustrator has no native DST export. The correct process is: design in Illustrator → export as SVG or AI → import into embroidery software (Wilcom, Hatch, Embird) → digitize → export as DST. Alternatively, export from Illustrator as PNG and send to a professional digitizing service for $12 flat.

Why does my DST file show only one color?

DST files do not store thread color data — only stitch coordinates and machine commands. Thread colors are assigned manually at the machine by the operator, based on a color sequence list or the digitizer's thread chart.

How do I convert a DST file to PES for Brother?

Open the DST in Brother PE-Design, Hatch, or Embird → export as .pes. Brother also offers a free online converter at myeditor.brother.com — no software download needed.

What is the maximum size for a DST design?

The DST format supports designs up to 1,200 mm × 1,200 mm (47" × 47"). In practice, your machine's hoop size is the real limit — commercial hoops typically range from 360 × 500 mm to 500 × 600 mm.

Can I convert a PNG or JPEG to DST directly?

Not accurately. Auto-conversion tools exist but produce poor stitch quality — rough paths, excessive jumps, density issues. The correct method is embroidery digitizing: a trained digitizer manually converts the artwork into machine-ready stitch data. Cost: $12 flat at True Digitizing, delivered in 2–12 hours.

What is the difference between standard DST and Wilcom DST?

Standard Tajima DST has a body size exactly divisible by 3 bytes. Wilcom's DST variant adds extended headers, making the body non-divisible by 3. Most embroidery machines accept both, but some older machines reject the Wilcom variant. Re-export as standard DST from Wilcom's export settings if compatibility issues arise.

How large is a typical DST file?

DST files are compact — typically 5 KB to 50 KB depending on stitch count. A left-chest logo with 8,000 stitches runs about 20 KB. The small size makes DST ideal for email delivery, USB transfer, and FTP.

⚡Quick Answer
A DST file is an embroidery machine format developed by Tajima that stores stitch coordinates, thread color changes, and movement commands — making it the most universally compatible embroidery file format in the industry.
Whether you need to open one, create one from a logo, export from Adobe Illustrator, or convert it to PES or JEF — this guide covers everything with exact technical data and no filler.

What Is a DST File?

DST stands for Data Stitch Tajima, named after the Japanese embroidery machine manufacturer that created the format in the 1980s. Despite its age, DST remains the industry standard for commercial embroidery production worldwide — and the most common embroidery file format used in professional shops.

Every DST file stores three types of machine data:

Stitch coordinates — exact X/Y positions where the needle penetrates fabric
Jump commands — machine movement instructions without stitching
Color change commands — stop signals that allow thread changes

DST files do not store color information. Colors are assigned manually by the machine operator. This is why opening a DST file in most software shows it in a single color — the actual thread colors are operator-selected at the machine.

How to Create a DST File: 3 Methods

Method 1: Professional Digitizing Service (Recommended)

Fastest and most reliable. No software or learning curve needed.

Prepare artwork — Send high-res PNG, JPG, PDF, or vector file (AI, EPS, SVG preferred)
Specify size — State dimensions in inches (example: "4-inch left chest")
Choose format — Request DST, or all formats (most services include all)
Submit and pay — True Digitizing: $12 flat, any complexity
Receive file — Delivered to email in 2–12 hours
Test stitch — Always test on scrap fabric before production run

Cost: $12–$25 at most professional services. True Digitizing: $12 flat rate, 2–12 hour delivery.

Method 2: Digitizing Software (DIY)

Best for those who digitize regularly and want full control.

Install embroidery software (Wilcom, Hatch, or Embird)
Import artwork as background layer
Trace design manually — assign stitch types (satin, fill, run) per element
Set stitch density — typically 0.4–0.45 mm spacing for satin stitches
Set pull compensation — add 0.3–0.5 mm expansion per element for fabric pull
Set underlay stitches — stabilize fabric beneath design
Export as DST — File → Export → select .dst
Test stitch on scrap fabric before production

Learning curve: 20–40 hours minimum before producing production-quality files.

Method 3: Auto-Digitizing (Avoid for Logos)

Most embroidery software has an auto-digitize button. Avoid it for logos, text, or anything with clean edges. Auto-digitizing produces excessive jump stitches, poor path planning, and designs that look rough when sewn. Use only for simple solid-fill areas.

How to Save a DST File in Adobe Illustrator

This is one of the most searched questions in the DST cluster — you cannot save a DST file directly from Adobe Illustrator. Illustrator is a vector design application, not embroidery software. It has no native DST export.

The correct workflow from Illustrator to DST:

Design in Illustrator as normal — keep clean vector paths, avoid gradients/shadows
Export as SVG or AI file — File → Export → SVG (or save as .ai)
Import into embroidery software — Open Wilcom, Hatch, or Embird → import your SVG/AI
Digitize the design — assign stitch types to each path element
Export as DST — File → Export → .dst

Alternative route (no embroidery software):

Export your Illustrator file as high-res PNG or PDF
Send to a professional digitizing service ($12 flat)
Receive DST file in 2–12 hours — machine-ready, all formats included

Why Illustrator can't export DST directly: Illustrator works with vector paths and anchor points. A DST file stores actual needle penetration coordinates, stitch angles, density values, and machine commands. These are fundamentally different data types — converting between them requires a digitizer's judgment, not a file export.

Plugins that claim Illustrator-to-DST export: Several third-party plugins exist (InkStitch via Inkscape, not Illustrator; Embrilliance Stitch Artist) but none produce production-quality output comparable to professional digitizing for complex logos.

How to Convert a DST File

DST to PES (for Brother machines)

Open DST in Brother PE-Design, Hatch, or Embird
File → Save As (or Export)
Select .pes from format dropdown
Choose your Brother machine model when prompted (sets hoop limits)
Save → transfer to machine via USB

DST to JEF (for Janome machines)

Open DST in Janome Digitizer, Embird, or Hatch
File → Export → select .jef
Verify design fits within Janome hoop (standard: 200 × 200 mm)
Save → transfer via USB or Janome memory card

DST to VP3 (for Husqvarna Viking / Pfaff)

Open DST in Hatch, Wilcom, or Embird
Export → select .vp3
Check hoop size compatibility for your Viking or Pfaff model
Transfer via USB

DST to SVG or PNG (for preview / print)

DST is stitch data, not an image. To create a preview:

Open in Wilcom, Hatch, or Ink/Stitch
Export as PNG at 300 DPI minimum
Result is a simulation image — not a vector

Tajima DST File: Technical Reference

The Tajima DST format was designed specifically for Tajima's commercial multi-head embroidery systems. Key Tajima-specific notes:

Header structure: The 512-byte header contains:

Label field: up to 8 characters (design name)
Stitch count: 7-digit zero-padded number
Color change count
Positive/negative extents (design bounding box in mm)
Design center coordinates

Wilcom DST variant: Wilcom embroidery software writes a modified DST that is identifiable by file size. Standard Tajima DST body size is always a multiple of 3 bytes. If (filesize − 512) mod 3 ≠ 0, the file is a Wilcom extended variant with additional metadata headers.

Control codes in DST:

Code	Function
Normal stitch	Needle down at X/Y coordinate
Jump stitch	Machine moves without stitching
Color change	Machine stops — operator changes thread
TRIM	Cut thread (some Tajima models)
END	Design end command
SEQUIN	Activate sequin attachment (specialty machines)

Maximum values:

Single stitch: 12.1 mm in any direction
Jumps longer than 12.1 mm: split into multiple jump commands automatically
Design area: 1,200 mm × 1,200 mm absolute maximum

Common DST File Problems & Fixes

Problem	Cause	Fix
Machine won't read file	Corrupted file or wrong DST variant	Re-export from software; try Wilcom vs standard DST variant
Colors wrong at machine	DST stores no color data	Assign thread colors manually by stop number sequence
Excessive jump stitches	Poor digitizing path order	Redigitize with optimized path sequence
Design too large for hoop	Exceeds machine max hoop	Scale down in embroidery software
Stitches pulling / puckering	No pull compensation set	Add 0.3–0.5 mm pull comp; add underlay
File won't open in software	Wrong software type	Use embroidery-specific viewer (see list above)
Wilcom DST won't load on machine	Extended header variant	Re-export as standard Tajima DST in Wilcom
Design looks fine in software but bad when sewn	Density too high or too low	Standard density: 0.4–0.45 mm for satin; adjust per fabric type
