What is the .JEF format?
The Janome JEF format is the native format for Janome Memory Craft machines, with support for detailed color sequences and strict hoop-size validation. It stores color sequence stored per stitch block, and is natively read by Janome Memory Craft, Elna machines.
When you convert a BMP image to JEF, every stitch path, fill area, and satin column is encoded in the Janome JEF specification — ready to load directly onto your machine with no additional software.
Tips for better BMP → JEF results
- Use at least 300 DPI resolution for sharp stitch paths
- Increase contrast before uploading for more distinct color regions
- Limit colors to 6–12 for cleaner thread separation
- Simple, bold shapes produce better stitch quality than fine gradients
- For best results on Janome Memory Craft, Elna machines, test at 100 % zoom in your machine software before production
