Why convert DST to JEF?
DST is the Tajima stitch format, read by Tajima commercial machines and nearly every multi-needle or commercial embroidery machine — DST is the industry's most widely supported format. Convert to JEF when your Janome or Elna machine reads JEF natively. SewFlow re-encodes your existing stitches for the new format — it never re-digitizes, so the design sews out identically.
What happens to thread colours
DST files carry no thread-colour information (the format stores no thread colours at all — only stitches, jumps, and colour-stop commands), so SewFlow assigns a preview palette to each colour block. The stitch sequence and colour stops stay exactly as digitized — check every block in the free preview before downloading.

Frequently asked questions
Will my design stitch out the same after converting DST to JEF?
Yes. SewFlow re-encodes the same stitches rather than re-digitizing: stitch paths, jump and trim commands, and colour stops are preserved exactly, so the JEF file sews out identically to the original DST design.
Which machines read JEF files?
JEF (Janome Embroidery Format) is read by Janome Memory Craft and Skyline series machines, plus Elna eXpressive models. Copy the .jef file into the EMBF folder on a USB stick and open it from the machine's built-in file browser.
What happens to thread colours when converting DST to JEF?
DST files carry no thread-colour information (the format stores no thread colours at all — only stitches, jumps, and colour-stop commands), so SewFlow assigns a preview palette to each colour block. The stitch sequence and colour stops stay exactly as digitized — check every block in the free preview before downloading.
