Various embroidery designs formats can usually be converted between each other so they can be used on different sewing or stitching machines. The problem is usually with finding a software capable of conversion between formats you need. We know that SewWhat-Pro software supports both .emd and .emb files so seems like it should be your first choice.

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.
