What changes in the JEF to PES conversion
From Janome to Brother, two palette formats talk to each other: your JEF colors are transferred into the target PES, and the design stays ready to embroider on any Brother or Babylock machine.
- The color palette is kept; Janome thread references are mapped to the PES palette.
- Design dimensions stay identical, expressed in millimeters.
- The PES file adds design-name metadata the JEF does not fully carry.
- The stitch count does not change.

Understanding the JEF and PES formats
JEF .jef · as a source file
JEF sets out with the strengths of a Janome home format: stitches in tenths of a millimeter, explicit dimensions and a color palette backed by the Janome thread catalog. When the target format accepts a palette, your colors follow; otherwise, the section order remains the guide for reassigning threads.

- HoopsFixed table: from 80 × 80 mm to 140 × 200 mm
- ColorsPalette (Janome thread catalog)
- MetadataDesign dimensions, selected hoop
- Internal unitTenth of a millimeter
PES .pes · as an output file
As a target, PES produces a file every Brother and Babylock machine can read, ready to open in PE-Design, Embrilliance Essentials or Ink/Stitch. If the source carries no colors (DST, EXP), a default palette is built in thread-change order; otherwise the original palette is kept.

Machine compatibility and dimensions
JEF stores the design dimensions and a hoop code; the converted PES reuses the same millimeter dimensions and aligns with Brother hoops. A 130 × 180 mm Janome design remains a 130 × 180 mm design on Brother — provided the hoop of your machine accepts it.
