In order to create embroidery designs (*.emb) from a common image (like *.jpg) you need to use a special embroidery software that has a digitizing function, ie. a feature that allows the software to create a vector based design from a bitmap source. The result greatly depends on the complexity of the original image, so you may be a little disappointed if you try to digitize a photograph for example. Works well for simple pictures though, like logos.

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.
