Alpha-channel data in your WEBP is used as a no-stitch boundary, so transparent areas stay clean in the final embroidery.

Our AI engine adds underlay stitches and pull compensation automatically, reducing puckering and improving fabric stability on all stitch types.

Stitch density, satin column width, and fill angles are optimized for professional JEF output — no manual parameter tuning needed.

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 WebP 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 WEBP → JEF results
- Use at least 300 DPI resolution for sharp stitch paths
- Transparent areas will become no-stitch zones — use them to shape your design
- 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
