Future file types (Patreon)

I want to ask for yall opinions on what file type I should use in the future

I've been using PNG this whole time and the image quality is guaranteed. But recently I found out that while the image quality for JPG isnt perfect, it's not very noticeable and the file size is MUCH smaller, so if you download my images, they won't take up so much space

PNG
-Pros: Perfect image quality
-Cons: Very heavy file size (x10 larger)

JPG
-Pros: Small file size
-Cons: Imperfect image quality (barely noticeable imo)I added noise to both images, but you can see some difference in image quality between them

JPG is 1.43MB, while PNG is 14.4MB
