Before I can understand what EWWW IO does, I need to understand what happens to images in Wordpress.
I'm not a Web Developer but I know enough to get me through. Despite my knowledge I'm not quite sure how WordPress serves images.
Given that I know that Wordpress, your theme or your plugins automatically creates other copies of your image at other pixels dimensions respecting your aspect ratio.
My basic understanding is this.
In other words, I don't have a clue.
What I need to understand is why Browser Resizing takes place at all.

Here's the one I was thinking of: https://ewww.io/2018/06/14/resizing-images-wordpress/ And one I just ran across today: https://enginescout.com.au/wordpress-image-sizes/

I forgot about that YouTube Video. I still have a few questions.
Does WordPress upscale images larger than the Original full-size image.

this is one of our docs that briefly touches on some of what WordPress does in regards to the various "resizes": https://docs.ewww.io/article/20-why-do-i-have-so-many-images-on-my-site
But it certainly doesn't go into full details, and that's something I still want to do (and have on my todo list)

Seems like I might have written about that before. But if not, that's a good idea to write about how WP handles images, and I think it would fit in with one of the topics I already have on my todo list!

I'll try and find your blog post Shane. Even if you explained why browser resizing occurs would help a lot.

Nope, WP never upscales an image, but it does sometimes make the filesize larger when scaling images down. It's somewhat rare, but more common for 8-bit PNG images.
