What this conversion keeps and changes

Janome JEF colours are dropped in DST; the block order and trims are preserved.

Inside a JEF file

  • Read by: Janome, Elna and Kenmore machines.
  • Colours: colours as indices into a fixed palette, so each thread becomes the nearest palette entry.
  • Trims: zero-length jumps.
  • Longest stitch per record: 12.7 mm; anything longer is written as two.
  • Colours are indices into the Janome thread chart, which is what the machine screen shows.

Inside a DST file

  • Read by: Tajima, Ricoma, Barudan, Happy, SWF and most commercial machines.
  • Colours: no colours at all, only stops between blocks, so the operator threads needles from a colour sheet.
  • Trims: three consecutive jumps.
  • Longest stitch per record: 12.1 mm; anything longer is written as two.
  • DST stores stops, not colours: the operator threads the needles from a colour sheet.

When you need this conversion

Designs are sold in the format of the digitiser's software, and JEF is common because Janome use it. If your machine is one of the Tajima, Ricoma, Barudan, Happy and most commercial models, it wants DST. The stitches are the same; only the container changes, and the notes above are the whole list of what the container cannot carry. Applique designs built in the studio can be downloaded in DST directly, without converting.

Reverse: DST → JEFPES → DSTJEF → PESEXP → DST

How to use it

  1. 1

    Drop the JEF file

    Drag it onto the page or click to choose it. The file is decoded on your device and drawn on a hoop grid with its size, stitch count and colour blocks.

  2. 2

    Choose DST

    Pick the output format. Rotate or mirror here if the placement needs it; centring on the origin is what most machines expect.

  3. 3

    Download

    The file is written and read back on your device before the download starts.

  4. 4

    Copy the colours over

    DST stores no colours, so print the colour sheet from the viewer and set the needles from it on the machine.

Questions

What changes when converting JEF to DST?

Janome JEF colours are dropped in DST; the block order and trims are preserved.

Which machines read DST?

Tajima, Ricoma, Barudan, Happy, SWF and most commercial machines. DST stores stops, not colours: the operator threads the needles from a colour sheet.

Will the DST file stitch identically?

Yes for geometry: every needle position is kept to 0.1 mm. Colour and trim behaviour follow the target format's capabilities, described on this page.

Is the file uploaded?

No. Reading and writing happen in your browser; close the tab and nothing remains.

Does this work on applique designs?

Yes; placement, tack-down and satin blocks convert like any other stitches. If you need the cut file for an applique design you already own, use the cut-file tool after converting.
