Why convert DST to EXP?
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 EXP when your Bernina or Melco machine expects EXP. 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
Neither DST nor EXP stores thread colours — both formats use colour-stop commands only. The conversion preserves every stitch, jump, and stop exactly, so nothing is lost either way.

Download as EXP
EXP is preselected as the target — click Convert and the .exp file downloads instantly. Load via USB. EXP carries stitches and colour stops only, so you set the actual thread colours on the machine.
Frequently asked questions
Will my design stitch out the same after converting DST to EXP?
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 EXP file sews out identically to the original DST design.
Which machines read EXP files?
EXP (Melco Expanded format) is read by Bernina home machines and Melco commercial embroidery machines. Load via USB. EXP carries stitches and colour stops only, so you set the actual thread colours on the machine.
