Not every machine reads the same files. The format does not change the design, but it changes what the machine can reproduce: colours, stops, density and stitch order.
The formats you will meet
| Format | Extension | Origin | Strengths | Limits |
|---|---|---|---|---|
| Tajima | .DST | Industry | Universal, read everywhere | No colour names, no embedded preview |
| Brother | .PES | Home | Named colours, preview | Less universal outside Brother |
| Janome | .JEF | Home | Compact, stable | Few metadata |
| Melco | .EXP | Industry | Simple, robust | No colour information |
| Pfaff | .VP3 | Home | Good stop handling | Rare |
| Wilcom | .EMB | Professional | Rich (colours, objects) | Proprietary |
Why DST is the reference
DST dates back to Tajima machines and remains the industry exchange format. It holds coordinates and orders only: no thread names, no preview, no layers. That is both its weakness and its strength — every machine, from a home unit to a multi-head factory line, can open it.
The practical consequence: in a DST, colour is a position in a sequence. If your machine shows blue where you expected red, the file is not wrong — the thread mapping in the machine is.
DST or PES?
- Newer Brother machine: PES keeps colours and settings, which is more comfortable.
- Any other brand, or a production shop: DST is the safe choice.
- Selling designs: ship DST, optionally with PES alongside. That is what design shops do.
What is lost in a conversion
Converting EMB or PES to DST flattens the file:
- Colour names disappear, replaced by stitch order.
- Objects (text, shapes) become fixed stitches — no longer editable.
- Density settings are already applied, so they cannot be reversed.
In practice this rarely matters: DST is a production format, not a working format. Edit the source, export to DST, stitch.
Checking a DST before sending it
Three points, always the same:
- Stitch count: consistent with the design area?
- Size: inside the machine's hoop?
- Colour order: details before large fills?
A correct DST opens in any viewer and shows a continuous path, without long jumps across the design.
In practice
Our converter outputs DST directly, with preview, stitch count and dimensions. If your machine prefers PES, the DST to PES conversion happens in your brand's software with no visible loss on a simple design.
