so from its hard in the first opinion towards it is deathsimple ..
UHU !!
nothing wrong with keeping your tips and tricks behind closed doors though
I said "it isn't hard to bring it to below 500 KB" - that would mean it is easy, right. :)
I don't have any tips and tricks, set to jpeg, adjust colors, since picture will look better - at least I do it that way, and then save as, I check the pic size, if it is too big then I decide will I change the % of picture quality or will I resize it for e.g. 10 % and so on, and after maybe 30 seconds all done.
It would be great if there is no limit to picture size, I'm ok with the post limit size, but if someone will post only one picture, why limit it to 500 KB then.
EDIT: We are here to share our game screenshoots, not the sizes of our displays, right.
Anyway:
Here is link to some pic - original size 3.12 MB, went to 7.29 MB after adding collors,
https://images.hdqwalls.com/wallpapers/doom-eternal-4k-2020-75.jpg ....and down to 473 KB, and if you set it up to 1920x1080 I still think it is pretty decent, check attachment, it looks good enough for me, but everyone up for its taste.
...or 2048x1152, slightly better if you look carefully, and only 8 KB more :)
