Why convert SEW to PES?
SEW is the Janome SEW format, read by older Janome and Elna machines (Memory Craft 8000/9000 era) and some Bernina 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
SEW and PES both store thread colours, so your colour sequence transfers automatically — SewFlow re-encodes each thread into the Brother PEC palette. The SEW file stores thread colours as Janome palette indices, like JEF; 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 SEW 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 SEW 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.
