What changes when you convert
Every stitch is kept
Needle positions carry over exactly: both JEF and EXP store them in 0.1 mm steps. Moves longer than EXP allows are split automatically.
Colors become a color sheet
EXP doesn't store thread colors, only where they change. Download the ZIP to get a color sheet with the thread order.
Jumps become trims
Every jump between sections is written as a trim and a jump, so loose threads are cut on machines with an automatic trimmer.

JEF to EXP questions
The quickest way to see what it does with your artwork is to try it. It's free and takes about a minute.
Is converting JEF to EXP lossless?
The stitches are. Every needle position is copied exactly. Thread colors can't be stored in EXP, so they go into the color sheet.
Will my Melco machine read the converted file?
Yes, if it reads EXP. The file is written to the Melco EXP specification and checked against independent readers. Most Melco machines read EXP; your manual lists the exact formats.
Is my file uploaded anywhere?
No. The file is read and converted entirely in your browser, so it never leaves your computer.
Can I resize the design while converting?
Not in the converter, which keeps the stitches exactly as they are. To change the size, digitize the original artwork again in the free digitizer, since scaling stitch files changes their density.
