Convert PNG to JEF embroidery files
PNG is the best raster format to digitize from: edges stay sharp, colors stay flat and transparent backgrounds come through intact. Download a Janome JEF file for Janome, Elna machines.

Transparency is removed for you
A transparent background is detected and left unstitched, so only the artwork is sewn.
Flat colors separate cleanly
PNG doesn't add compression noise, so each color in your artwork becomes one thread color.
Resolution matters
Export at least 1,000 px across. Small PNGs are enlarged and smoothed, but fine details may merge.

The Janome JEF format
JEF is Janome's embroidery format, used by the Memory Craft and Skyline embroidery machines and by Elna machines built on the same platform.
Thread colors are mapped to Janome's thread palette. The file also records the smallest standard Janome hoop the design fits in.
Moves longer than 12.7 mm, the format's limit, are split into shorter jumps automatically.
Tips for the best result
- Export logos from your design tool as PNG with a transparent background.
- Remove drop shadows, glows and gradients first: thread can't blend colors.
- Thin lines should be at least 0.5 mm wide at the final size, or they become a running stitch.

PNG to JEF converter questions
The quickest way to see what it does with your artwork is to try it. It's free and takes about a minute.
Does a transparent PNG work?
Yes. Transparent areas are treated as background and never stitched. Background-colored shapes inside the design are listed as their own color so you can decide whether to stitch them.
What resolution should my PNG be?
Around 1,000 to 2,000 pixels across is ideal. Larger files are scaled down for analysis, and very small ones are enlarged and smoothed.
Which Janome hoop will the design use?
The file is tagged with the smallest standard hoop it fits (50×50, 126×110, 140×200 or 200×200 mm). Set the size in the digitizer to fit your hoop before downloading.
Can I change the thread colors?
Yes. Choose the Janome thread chart in the digitizer and pick any thread for each color before you download.
Is this embroidery digitizer really free?
Yes. You can digitize and download as many designs as you like, in every format, without signing up. Everything runs in your browser, so there are no server costs to pass on.
Is my image uploaded to a server?
No. Your image is processed entirely on your own device in your web browser and is never uploaded. If you sign in and save a design, only the finished stitch file, a small preview and its thread colors are stored in your account, never the original image.
