Convert JPG to JEF embroidery files
JPG files work well once their compression noise is cleaned up. The digitizer smooths JPEG artifacts and blurry edges before it picks thread colors. Download a Janome JEF file for Janome, Elna machines.

Compression noise is filtered
"Clean up noise" removes the speckles and color fringes JPEG adds around edges, so they don't become extra threads.
Solid backgrounds are removed
A white or single-color background around the artwork is detected and left unstitched.
Fewer colors, cleaner result
Cap the number of colors if gradients or shading split into too many thread colors.

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
- Use the highest-quality JPG you have. Screenshots of small logos lose detail.
- If the logo sits on a busy background, crop it or remove the background first.
- For photos, start with 4 to 6 colors and adjust from there.

JPG 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.
Will JPEG artifacts show up in the embroidery?
No. Noise reduction and anti-alias cleanup run before color separation, so blocky artifacts and soft edges are folded into the nearest real color.
Can I convert a photo saved as JPG?
Yes. Photos are simplified into a few flat thread colors, which suits simple, high-contrast pictures best. See the photo-to-embroidery page for tips.
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.
