About WebP files
WebP is the modern web image format with transparency and strong compression. WebP supports transparency like PNG, so graphics saved straight from the web convert directly — transparent pixels are treated as background and stripped automatically.
Tip: Right-click-saved web graphics are often WebP already; upload them as-is, no need to convert to PNG first.
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 WebP to JEF?
Upload the WebP on this page — SewFlow digitizes it automatically (colour detection, background removal, stitch generation) and shows a free preview. Pick your size, then download the JEF file ready for Janome & Elna machines.
Can I upload a WebP image saved from a website?
Yes — WebP uploads work directly, including transparent WebP. Keep in mind that web images can be small; artwork at 500px or larger on its shortest side gives the digitizer more edge detail to work with.
Which machines use JEF files?
JEF is read by Janome Memory Craft and Skyline series machines, plus Elna eXpressive models. Copy the .jef file into the EMBF folder on a USB stick and open it from the machine's built-in file browser.
