What changes in the PES to JEF conversion

PES and JEF are both home formats that can store a palette: converting from Brother to Janome keeps your colors, simply remapped to the Janome thread catalog.

The color palette is transferred; thread references are mapped to the closest Janome catalog entries.
The stitch count and design dimensions stay identical.
Brother-specific metadata (extended design name, version-specific palette) is only partially carried over.
No color check needed on the machine in most cases.

Understanding the PES and JEF formats

Format PES .pes

PES is the native format of Brother and Babylock home embroidery machines (and Bernina Deco). It is one of the most widely distributed formats: most design shops offer it by default. A PES file stores stitches (positions, jumps, trims), a color section and metadata — design name, dimensions in millimeters and, depending on the version, a thread palette. When converting, these elements are read and re-encoded into the target format: the stitch count and design dimensions stay identical, while the color palette is only kept if the destination format can store one. To open a PES file outside a Brother machine: PE-Design, Embrilliance Essentials, Ink/Stitch (free) or Wilcom TrueSizer (free).

Format JEF .jef

JEF is the native format of Janome, Elna and Kenmore machines. It stores stitches, design dimensions in millimeters and a color palette backed by the Janome thread catalog: original colors survive conversion, as long as the source file carries one. Like most home formats, it embeds no digitizing notes and no per-brand thread table. When converting from a « flat » format (DST, EXP) that carries no palette, software assigns default colors in thread-change order: check them on the machine before starting the embroidery. To open a JEF file: Janome Digitizer or Wilcom TrueSizer (free).

Machine compatibility and dimensions

The conversion changes neither the stitch count nor the design dimensions: a 90 × 90 mm design remains a 90 × 90 mm design. The maximum embroiderable area depends on your machine and hoop, not on the file: simply check that the converted design dimensions fit inside your hoop. All formats supported here (PES, DST, JEF, EXP, VP3) express stitch positions in the same base unit, which allows conversion without any rescaling.
