How do I create a cool needs more jpeg effect

what I want to do is to be able to make all my sprite look like they have been put through http://needsmorejpeg.com/ simple put them through needs more jpeg. the problem is I want to fade the effect in is there a construct 3 effect that can do this or do I need something else

There are plenty of C3 effects you could use and if the effect accepts parameters then you can change them at runtime with a system action called set layer effect parameter or set layout effect parameter.

Downscale the object, paste it into Drawing canvas, then reload the sprite with the paste. Upscale.
