$\begingroup$ Didnt have much progress to be honest. I have tried adding camera grain, but the effect is quite different. $\endgroup$– ManveruCommented Apr 2, 2022 at 13:07

1$\begingroup$ Did you try saving your render as a jpeg with very low quality settings ? $\endgroup$– thibsertCommented Apr 2, 2022 at 13:58

2$\begingroup$ Maybe actually save the file as actual jpeg with a File Output node as intermediate step, then reintroduce it as an image texture back into compositing tree. $\endgroup$– Duarte Farrajota Ramos ♦Commented Apr 2, 2022 at 14:34

1$\begingroup$ i tried something here, separating in channels, pixelate, and a couple of chained filters, blender makes it look more complex though..! it's just an aproximation, maybe try with some images besides of render as each one needs different settings $\endgroup$– alambreCommented Apr 9, 2022 at 16:10

its a pain, and its a chore, but just use a lot of pixelate nodes. Pixelate the image by an extreme amount, then mix that with the same image pixelated by a lesser amount, and do that over several times until you reach the desired resolution. Blur nodes can be used if the compression looks too intense.
