Convert now — no account neededWhat to know about starting from a logo
A logo is the most common thing anyone digitizes and the most demanding, because people know what it is supposed to look like. Flat colours and hard edges convert well; thin outlines, small tag lines and drop shadows do not.
Logo to JEF specifically
Janome hoop sizes are the binding constraint on logo width, and JEF records the hoop in the file, so a logo sized for a hoop you do not own will simply be refused. Size it against your actual hoop first. Your brand colours are also matched to Janome's thread chart on export, so check the nearest entries if the match matters.
How to convert Logo to JEF
- Upload your logo. Decide the finished width first — a left chest logo is about 90mm — then look at what is still legible at that size. Anything under about 1.2mm wide cannot be stitched as its own shape, so a hairline keyline or a 6pt tag line has to be thickened or dropped.
- Set the finished size. Work in millimetres and set it before you judge anything else — every decision about detail depends on how big the design will be. Detail that survives at 150mm disappears at 60mm.
- Reduce the colours. Each colour is a thread change on the machine. Pick the fewest that still read as your artwork.
- Check the preview, then export as JEF. The stitch preview plays the design in the order the machine will sew it, so you can catch problems before there is thread in the hoop.
About the JEF format
JEF is the native format for Janome and Elna. JEF stores thread colours and also records which hoop the design is meant for, so it is worth picking the right hoop size at export rather than letting the machine complain about it later.
What makes the difference to the result
Digitizing is not tracing. The converter decides how each region gets filled, which direction the stitches run, where the underlay goes and how much to compensate for the fabric pulling the design in as it sews. Those decisions are what separate a design that stitches cleanly from one that puckers, gaps at the edges or takes twice as long as it should.
- Size before everything. A shape narrower than about 1.2mm cannot be stitched as its own satin column; it has to be widened or dropped.
- Fewer colours, better result. Every extra colour is a thread change, a trim and a chance for registration to drift.
- Flat beats subtle. Gradients, glows and soft shadows have no equivalent in thread and become banding.
- Check the stitch order. The simulator plays it back so you can see the sequence before you sew it.
Already have the vector?
If whoever designed the artwork can send you the SVG, AI, EPS or PDF, use that instead. Converting from vector skips the whole business of inferring edges from pixels, and the difference is visible in the finished stitch-out. See SVG to embroidery.
Common questions
How small can the text in my logo be?
Roughly 6mm cap height is the floor for legibility, and it is a physical limit rather than a software one — below that the enclosed holes in letters fill in with thread. A tag line that sits under 6mm at your finished width has to be enlarged, set in a bolder face, or dropped.
Why did my Janome refuse the design?
Usually the hoop. JEF records which hoop a design expects, and Janome machines decline anything that does not match the hoop they think is attached. Set the finished size against a hoop you actually own before exporting.
Does JEF store thread colours?
Yes, as an index into Janome's own thread chart rather than as an RGB value. Each colour you choose is matched to the nearest thread Janome sells, and if two of your colours would land on the same entry, one is pushed to its next-nearest so the two stay distinct.
JEF or SEW for a Janome?
JEF unless the machine cannot read it. SEW is the older format from the Memory Craft 5700, 8000 and 9000 era and caps at twelve thread colours; JEF has no colour ceiling and records hoop information.
Is it free?
Yes, to start. A free account converts up to three designs a day at up to three thread colours and three inches, with every export format available. Premium lifts the colour and size limits and raises the daily allowance.
