Is there a way to smooth the outlines of the edges/vertices/faces?

[firstlast1234]

I have an object, but the edges of it are all squiggly and jagged. Is there some way I can smooth them out?

Thanks in advance.

Do we talk about the geometry or the shading?

Smooth shading can be found in the Object menu.

For smoothing the geometry, well, this depends of your geometry and what you want to do. You could add a subdivision surface modifier. Or a remesher. Or a Smooth modifier. Or simply model more accurate
