What is a JEF file?
JEF is the format of Janome machines, also used by Elna and some Kenmore models. It stores every stitch, the thread colors from the Janome chart and the hoop the design was made for.
What is a XXX file?
XXX is the Singer format, also read by Compucon software. It stores the stitches, color changes and exact thread colors.
Is the conversion exact?
Every stitch keeps its position. After converting, we read the new file back and compare it with yours, stitch by stitch; a file that doesn’t match is never offered. XXX keeps the exact thread colors.
How to load the XXX file onto your machine
Copy the file to a USB stick and plug it into your machine, or send it with your machine maker’s app or software. Hoop your fabric with a stabilizer, choose the design on the screen and start sewing.
