Yes, but this is only true as long as your graphic can be represented
reliably in the target format. And yours cannot.

It is like asking for conversion of a vector image of a circle into a
target format that only supports straight lines (also vector format,
but without support for splines).

If this is your own graphic, you need to alter it in such a way that
it will be representable with what PDF is capable of doing. See the
chapter on smooth shading. You can do a lot with that, but it might
require a bit of extra effort (and then maybe hunting developers to
fix rendering bugs; Apple doesn't know how to render smooth shading
properly and even used to crash).
