4K Screenshots to 1080p

[BornToBattle]

As the title states, how’s the best method to do this? I took screenshots in 4K but waaaay to big obviously to submit online here so need to downgrade the image. I’ve got about 30 or so to post FYI. Weird thing is while taking the screenshots it formatted them in .bmp which according to the site they won’t accept. 
 

I did reduce the file to 1920x1080 but that doesn’t work as they still go over 30MB in size each. I’m unfamiliar with downgrading screenshots to 1080p. If I find a way to do that then I guess next step in to converter them all to something like a .jpg image. I’m trying to post in the thread that Jason requested screenshots for.

So far every time I do a search online it’s all for blasted videos! It must be possible with a pic, or you would think so, or it’s how to take 4K screenshots on a 1080p monitor - never the opposite! Argh!

 

Thanks in advance!
