Why convert JEF to PES?
JEF is the Janome Embroidery Format, read by Janome Memory Craft and Skyline series machines, plus Elna eXpressive models. Convert to PES when your Brother or Baby Lock machine needs PES. 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
JEF and PES both store thread colours, so your colour sequence transfers automatically — SewFlow re-encodes each thread into the Brother PEC palette. The JEF file stores thread colours as indices into the Janome thread palette; the converted PES file embeds a PEC colour block using the 64-colour Brother thread palette.

Frequently asked questions
Will my design stitch out the same after converting JEF to PES?
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 PES file sews out identically to the original JEF design.
Which machines read PES files?
PES (Brother embroidery format) is read by Brother PE800, SE600/SE700, Innov-ís and Luminaire series machines, and Baby Lock machines. Copy the .pes file to a USB stick and open it from the machine's Embroidery menu.
