Why convert SEW to DST?
SEW is the Janome SEW format, read by older Janome and Elna machines (Memory Craft 8000/9000 era) and some Bernina models. Convert to DST when you're sending the design to a commercial embroiderer or multi-needle machine — DST is the industry's common denominator. 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 don't store thread colours — the format stores no thread colours at all — only stitches, jumps, and colour-stop commands. Your stitch order and every colour stop are preserved exactly; you assign the actual thread colours at the machine, matching the free preview shown before you convert.

Frequently asked questions
Will my design stitch out the same after converting SEW to DST?
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 DST file sews out identically to the original SEW design.
Which machines read DST files?
DST (Tajima stitch format) is read by Tajima commercial machines and nearly every multi-needle or commercial embroidery machine — DST is the industry's most widely supported format. Transfer by USB or network. Because DST carries only colour stops, you assign the actual thread colours at the machine.
