Can anyone recommend good file conversion apps/programs that exist for converting jpegs to svg files?  I have used one app, which exports a decent 'line drawing' svg, but it does not retain the colors of the native jpeg image.  Appreciate any and all feedback.  Thanks.

I have used this for other file conversions but I am not sure if it will work for yours. 

Just a suggestion
