Subdivision modifier renders with Viewport Subdivisions in Edit Mode Modelling a mask in Blender. Used subdivision modifier with 1 subdivision on the Viewport and 2 on the render. Like this:



I made sure the render and realtime buttons were active as can be seen above.

In object mode, behaviour is what I expected, 1 subdivision applied in the Viewport, 2 in the render, like so:

Object mode Viewport



Object mode Render



If I enter Edit Mode, the viewport still behaves as expected, but the render always shows the number of subdivisions set for viewport, like so:

Edit Mode Viewport



Edit Mode Render



I am new to Blender, do we have to exit Edit Mode and then render?
I am also new to Blender and noticed this recently. I believe it's due to the fact that you cannot apply modifiers (e.g. Subdivision Surface) while in Edit Mode. When you render, it still takes into account whether you're in Object or Edit Mode. So yes I believe you must be in Object mode for the modifier to be applied during the render.
