SVG to stitches

Digitizing works from the vector outlines in your SVG, so edges come out exactly as drawn. A stroked path becomes a satin column of that path's own width; a filled shape gets underlay, angled fill rows and a sealed edge; narrow filled shapes — outlined lettering — are found and satined across the stroke. Export from Illustrator, Figma, Inkscape or Affinity with text converted to outlines.

What is a JEF file?

JEF is the native embroidery format of Janome machines, also used by Elna and other Janome-built models.

Besides the stitches, a JEF file records which Janome thread colour each block uses and which hoop the design was prepared for. EmbroViewer shows both the colours (from Janome's thread chart) and the real design size, and you can switch the hoop outline to see how the design sits in any standard hoop.

How to open a JEF file online

Scroll up and click Open files, or drag your .jef file anywhere onto the page.

The design appears instantly. Zoom with the mouse wheel, drag to pan, press Space to play the sew-out.

Choose your hoop from the hoop menu to check the fit, and open Stats for stitch count, size, colours and run time.

Save a PNG preview or the thread list if you need to share it.

What you can check

Exact design width and height in mm or inches, and whether it fits a 4″×4″, 5″×7″, 6″×10″ or larger hoop

Stitch count, colour changes, jumps, trims, stitch density and thread length

Estimated sewing time

Thread colours and the stitch order, with stitch-by-stitch playback

Machines: Janome and Elna embroidery machines, including Memory Craft models.

Check Janome design dimensions and colour order

A JEF design can contain palette references and hoop information. Compare the actual design dimensions with your machine's supported sewing area, rather than relying on the file name. The viewer's generic hoop outlines are visual references; they do not certify compatibility with every Janome model.

Frequently asked questions

How do I view a JEF file on a Mac or Chromebook?

Open EmbroViewer in your browser and drop the file in. It works on any modern browser without installing anything.

Will this JEF design fit my 5×7 hoop?

Choose the 130×180 mm (5″×7″) hoop from the hoop menu above the design. EmbroViewer shows whether the design fits and by how much.

Can EmbroViewer convert JEF to PES or DST?

Not yet. It views JEF files; format-to-format conversion is planned.
