What Are Embroidery File Types?
Embroidery file types are digital blueprints that hold every stitch command, color sequence, and machine instruction needed to bring a design to life. Without the right file, even a perfectly digitized design won’t stitch properly.
Think of these files as the “language” your embroidery machine speaks. They ensure your design runs smoothly from software to fabric.
There are three main embroidery file types every small printing business owner or hobbyist should know:
Machine File Formats
Expanded File Formats
Native File Formats
Each has a unique role in embroidery digitizing and production.
Evolution of Embroidery File Types
When embroidery digitizing first began, DST (Tajima) was the most widely used format. It was simple and worked with most commercial machines. The catch? It didn’t store thread color data, so embroiderers had to assign colors manually.
As machines became more advanced, formats like PES (Brother, Babylock), JEF (Janome), and VP3 (Husqvarna Viking, Pfaff) emerged. These added helpful features such as built-in color data, larger hoop support, and automatic trims.
The result? A growing variety of file types—each optimized for specific brands and machine capabilities.
1. Machine File Formats
What Are Machine File Formats?
These are the stitch-ready files your embroidery machine directly reads. Unlike editable files, they only contain stitching commands, not design properties.
Purpose of Machine Formats:
Guide the needle path and stitch order.
Ensure machine compatibility.
Provide a ready-to-stitch file for production.
Popular Machine Embroidery File Types:
PES – Brother, Babylock
DST – Tajima (industry standard)
JEF – Janome
EXP – Melco, Bernina
VP3 / HUS – Husqvarna Viking, Pfaff
XXX – Singer

Every brand created its own format to support unique features and encourage machine loyalty.
Why Do Formats Have Variants?
Just like software updates, formats evolve. For example, older Brother machines may only accept PES v5, while newer models handle PES v10 or higher.
2. Expanded File Formats
What Are Expanded Formats?
Expanded files are universal stitch files used across different machines. They store only stitch placement data—no advanced editing details.
Common Expanded Formats:
DST – Tajima (widely recognized)
EXP – Melco/Bernina
When to Use Expanded Formats:
Running the same design on multiple machines.
High-volume production where editing isn’t required.
Quick, lightweight files that load fast.
Key Characteristics:
Universally compatible.
Small file sizes.
Stitch-only data (limited editing).
Highly reliable for commercial use.
3. Native File Formats
What Are Native Formats?
These are the working files created in embroidery digitizing software. They store every detail of the design—stitch type, density, underlay, color charts, and more.
Why Native Formats Matter:
If a client later requests a size adjustment or color change, native files let you edit without losing quality. Machine-ready files like DST or PES can’t offer that flexibility.
Examples of Native Formats:
EMB – Wilcom
CND / OFM – Melco
PXF – Pulse
JAN – Janome
Key Traits:
Fully editable in their original software.
Not machine-readable (must be converted).
Store complete design instructions.
Managing Embroidery File Types
Running a small printing business means juggling multiple formats. The best approach?
Organize files by type (Machine, Expanded, Native).
Use clear naming conventions (e.g., ClientName_Logo_V2.PES).
Always save a native master copy for future edits.
Can You Convert Between File Types?
Yes—but with limitations. Conversion software can change PES to JEF, DST to EXP, etc. However, details like color data or advanced stitch properties may be lost. Always keep your native file as the master and export from there.
Can Embroidery Files Be Edited Directly?
Native formats (EMB, OFM): Fully editable.
Machine/Expanded formats (DST, PES, JEF): Limited editing; resizing can distort stitches.
For professional results, editing should always be done in the native file.

Frequently Asked Questions
1. What file format do most embroidery machines use?
Commercial machines often rely on DST, while home machines like Brother or Babylock use PES. Always check your machine’s manual to confirm compatibility.
2. Can I convert JPG or PNG into an embroidery file?
Yes, but not directly. You’ll need embroidery digitizing software to convert artwork (like JPG or PNG) into a stitch file such as PES or DST.
3. What’s the difference between machine and native files?
Machine files (DST, PES) are ready-to-stitch and not editable. Native files (like EMB) are editable design masters used to create machine-ready files.
4. Why do embroidery file types have so many versions?
As machines evolve, formats update to support larger hoops, advanced stitches, and new features. Older machines may not read the latest versions.
5. Can embroidery files be resized without issues?
Only native formats resize cleanly. Machine files can distort or lose stitch quality if scaled. Always request or keep a native file for editing.
