A practical guide to embroidery file formats for embroidery businesses, apparel brands and machine-embroidery hobbyists
The three embroidery file formats at a glance
| Format | Common association | Best check |
|---|---|---|
| DST | Tajima; commercial use | Machine manual |
| PES | Brother; Baby Lock | Model specifications |
| EXP | Melco; BERNINA | Manual or dealer |
Choosing the right embroidery file format is essential before a design reaches your machine. Unlike a JPG, PNG or other ordinary image, an embroidery file contains stitch instructions that the machine can follow. Those instructions define the path of the needle, the order of the stitched areas and other machine commands. A design may look correct on screen yet still be unusable if its format is not supported by your machine.
DST, PES and EXP are three common embroidery file formats, but they are associated with different machine families and workflows. There is no single answer that fits every model. The practical rule is simple: identify the format your exact machine accepts, then ask for the design in that format.
DST is the long-standing commercial standard
DST is the Tajima embroidery format. It has been used in commercial embroidery for decades and is widely treated as an industry standard for sharing stitch files. Most commercial embroidery systems can read DST, which makes it a common delivery format for contract embroiderers, uniform suppliers, promotional-product businesses and production shops operating more than one machine brand.
A DST file carries the instructions needed to run the stitch path, including movements and colour-change stops. However, it is a machine file rather than a rich, editable design source. Thread colours may appear differently when the file is opened on another system, so the operator should follow the production colour sheet or assign the correct threads at the machine.
Choose DST when your machine documentation lists it, when a commercial embroidery shop specifically requests it, or when you need a broadly readable production file. Wide compatibility does not remove the need to check hoop size, design dimensions and the limits of the exact machine model.
PES is designed for Brother and Baby Lock workflows
PES is commonly associated with Brother and Baby Lock home embroidery machines. It is a familiar format for hobbyists, home-based embroidery businesses and small studios that use machines from these brands. If your manual or model specifications identify PES as a supported format, it will often be the straightforward choice for transferring a design to the machine.
Do not assume that every Brother or Baby Lock model behaves in exactly the same way. Machines can differ by generation, transfer method, embroidery area and supported file versions. Confirm the accepted format and any size restrictions before ordering or downloading a design. If you are sending artwork for digitizing, include the machine make and model so the file can be prepared for the right workflow. See our embroidery digitizing service page.
EXP is used with Melco and BERNINA systems
EXP is associated with Melco and BERNINA embroidery workflows. It is used as a machine-readable stitch format, but the way it is packaged can vary. In a Melco workflow, an EXP file may be supplied as the stitch file itself. A BERNINA USB EXP export may also be accompanied by an INF file for thread-colour information and a BMP file for the design preview.
That distinction matters when transferring a BERNINA design. If your machine or software expects the companion files, keep them together rather than copying only the EXP file. The machine manual is the best source for the precise transfer procedure and supported formats for your model.
Your machine model determines which embroidery file formats you need
Brand associations are a useful starting point, not a substitute for model-specific instructions. A newer machine may accept several formats, while another model from the same manufacturer may have narrower requirements. Before you order digitizing or convert a file, use this three-step check:
- Read the manual: Look for “supported embroidery formats,” “design file types” or the section about importing designs.
- Check the model specifications: Use the manufacturer’s documentation for your exact model, not a general list for the brand.
- Ask the dealer: If the manual is unclear, give the dealer or manufacturer support team your full model number and ask which format they recommend.
Also confirm the design size, hoop dimensions and transfer method. A supported extension alone does not guarantee that a design fits the machine’s embroidery area. When requesting a custom file, share the intended finished size and fabric as well as the machine details. You can submit these requirements through the embroidery digitizing order page.
The wrong embroidery file formats need a real conversion
If you receive the wrong file type, do not change the letters after the filename. Renaming design.dst to design.pes does not translate the stitch data; it only changes the label that your computer displays. The machine may reject the renamed file, or software may report that it is invalid.
Instead, open the original design in compatible embroidery software and export it properly to the required machine format. If you do not have the software or the source file, ask the digitizer to re-export the design. A professional conversion preserves the stitch commands in a format the destination system can interpret.
Conversion also deserves a visual and physical check. Review the design dimensions, colour sequence and stitch simulation, then run a test stitch on similar fabric with the intended stabiliser, thread and needle. If the design requires more than a format change — for example, a different size or preparation for a new fabric — it may need adjustment or re-digitizing rather than a basic conversion.
Order the correct machine-ready file from the start
The easiest workflow is to provide the required format when you place the order. N Digitizing offers 100% manual digitizing and can deliver machine-ready DST, PES or EXP files. Its stated delivery window is 4–12 hours. Include your machine make and model, required format, finished size, fabric type and a clear copy of the artwork. See our embroidery digitizing service page.
Keep the editable source from your digitizer when available, as well as the final machine file and any production notes. That gives you a clearer route if the design must later be resized, adapted for a different garment or exported for another embroidery machine. The correct file format is the final handoff; good digitizing and a test stitch are what turn that file into reliable production.
Frequently asked questions
What is the most common commercial embroidery file format?
DST is the long-standing commercial standard and is readable by most commercial embroidery machines. Always confirm support for the exact machine model.
Do Brother embroidery machines use PES files?
PES is commonly associated with Brother and Baby Lock home embroidery machines. Check the manual or model specifications because support and file requirements can vary.
Is EXP the same for Melco and BERNINA?
EXP is associated with both systems, but packaging can differ. A BERNINA USB EXP design may include companion INF and BMP files for colour information and preview data.
Can I turn a JPG or PNG into an embroidery file by renaming it?
No. An image does not contain stitch instructions. It must be digitized into a machine-ready embroidery format.
Can I convert DST to PES or EXP?
Yes, compatible embroidery software or a digitizing service can export a design in another supported format. Review the converted file and test-stitch it before production.
Which format should I request from a digitizer?
Request the format listed for your exact machine. Share the machine make and model, along with the finished size and fabric, so the digitizer can prepare the correct file.
