Which file format your embroidery machine needs
PES, DST, JEF, EXP, VP3 or XXX: which format each embroidery machine brand reads, what each file holds and what to check when converting.

You bought a design, copied it to the USB stick, and your machine can't see it. Nearly always the problem is the format: every machine brand reads its own files.
The most common formats
| Format | Brands that use it |
|---|---|
| PES | Brother, Baby Lock |
| DST | Tajima and most commercial machines |
| JEF | Janome, Elna |
| EXP | Melco, Bernina |
| VP3 | Husqvarna Viking, Pfaff |
| XXX | Singer |
There are more (HUS, VIP, SEW, U01, TBF…), mostly older versions or brand-specific ones. When in doubt, check your machine's manual: it always says which extension it reads.
What an embroidery file holds
An embroidery file isn't a picture. It's a list of instructions for the machine: where to drop the needle, when to jump, when to trim and when to change color. That's why you can't "convert" a JPG into a PES by renaming it.
Some formats hold more information than others. DST, for example, stores the stitches but not the thread colors: when it opens, the machine knows when to change color, but not which one to use. If you convert from DST to PES, you'll need to assign the colors yourself.
Converting without damaging the design
Converting between formats changes the language, not the stitches. A good converter keeps every stitch exactly as it is. Even so, check three things:
- That it fits your hoop. A 5 × 7 in design won't go into a 4 × 4 in hoop, even in the right format. The machine will refuse it or ask you to change hoops.
- The colors. After converting, check that the thread order and colors are what you expect.
- The size. Scaling a design by more than 10 or 20% without redigitizing it changes the density: smaller turns out too tight and larger leaves gaps.
If you don't know your machine's model
Look for the label on the back or underneath the machine, or the information screen in its menu. With the brand and model you'll know the format and your hoop sizes.
In Satinwise you choose your machine once (there are 28 models, or you can create a custom one) and the converter delivers the right format and warns you if the design doesn't fit your hoop.
