Convert DST to JEF
Turn a Tajima DST into a JEF for a Janome or Elna machine. The stitches come across exactly, DST’s jump-burst trims become real JEF trims, and the file gets the Janome hoop it needs.

Your file is read in memory and discarded right away. We never store it.
What carries over
Stitches, colour stops and the size are unchanged. The converter reads three jumps in a row as a trim and writes a proper JEF trim command, which Janome machines cut on.
What doesn’t
Nothing the DST had. But DST never stored colours, so the JEF gets placeholder colours from Janome’s palette, one per colour block. Use the colour sheet that came with the design, or ask the sender for the colours.
Which machines read JEF
JEF is the default format of Janome and Elna embroidery machines. Several current Janome models read DST directly (the MB-4S, MB-7 and Skyline S9, for example), but others, like the Continental M17 and MC550E, don’t list DST at all. For those, a JEF is the only way in.
Size, hoops and stitch length
The design keeps its size, and the converter records the smallest standard Janome hoop it fits: 50 × 50, 126 × 110, 140 × 200 or 200 × 200 mm. Designs made for commercial machines are often digitized large; if one is bigger than your largest hoop, you need a smaller design. Check it in the viewer first.
If the JEF file doesn’t sew right
- Long jump threads where trims should be: the DST used a jump count other than three per trim. Cut those threads by hand, or ask for the file in another format.
- The colours make no sense: they’re placeholders. The machine stops at each colour change; thread the colours from the colour sheet.
DST to JEF: questions
My Janome reads DST. Should I still convert?
You don’t have to. A JEF shows the colour list and hoop on the machine’s screen and has real trim commands, while a DST relies on the machine reading jump bursts as trims.
Does converting fix a design digitized for another fabric?
No. A converter copies stitches; it can’t change density, underlay or pull compensation.
