Creating embroidery designs is possible from both vector and bitmap sources. Whilst it is somewhat easy from vector graphics, it can be pretty tedious from a raster picture. You will need to look for an embroidery program with digitizing function, ie. a function that allows users to make embroidery designs (like .cnd files for Melco machines) from JPEG sources.
Convert JPEG bitmap image format to Melco embroidery design file.
We found one software available in the database for this conversion.

The table with program actions contains information about what each program is capable of doing with their files. This may be a good pointer for further searches for certain file conversions and help you find the converter you are looking for if our search result is insufficient for you. However, it is far from perfect and may sometimes show results which are not really usable because of the nature of the software handles the files. So a conversion that appears as possible, just because of matched actions, may in fact not be possible.
