About PNG files
PNG is a lossless image format with full transparency support. Transparent pixels can be treated as background without estimating where the subject ends. Lossless compression avoids JPEG-style edge noise, but gradients, tiny details, and anti-aliased edges are still simplified into stitchable colour regions.
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.

Frequently asked questions
How do I convert a PNG to JEF?
Upload the PNG on this page — SewFlow digitizes it automatically (colour detection, background removal, stitch generation), shows a free preview, and lets you save the design to your account. Pick your size, then download the JEF file for Janome & Elna machines with a paid plan or bonus credit.
Does a transparent PNG background help the conversion?
Yes — transparency is the cleanest possible input. SewFlow treats transparent pixels as background automatically, so only your actual artwork is digitized, with no halo or leftover background patches.
