Make a circle?

Is there any way to take a non circular outline and make it into a circle in bolender? I know you can take an object and turn it into a sphereical form, how about a circle? I’d like to take an outline and turn it into a circle.

Circle option in the Loop Tools addon (enable in user preferences)

The ‘To Sphere’ tool in blender

Like many tools in Blender, looptools circle and to sphere are sensitive to object scale. In object mode, ctrl+a -> scale (and perhaps rotation too) to apply, if you find your circles are getting distorted.

Thanks guys! Fast answers.
