About PNG files
PNG is a lossless image format with full transparency support. A transparent PNG background is detected automatically, so your design's edges come out clean without any manual background removal. Lossless compression means no edge artifacts — colour regions trace exactly as drawn.
Tip: Export logos and clip-art as PNG with a transparent background for the cleanest stitch regions.
About the JEF format
JEF (Janome Embroidery Format) is read by Janome Memory Craft and Skyline series machines, plus Elna eXpressive models. The format stores thread colours as indices into the Janome thread palette. Copy the .jef file into the EMBF folder on a USB stick and open it from the machine's built-in file browser.
