Some Pictures Are Too Large For US Satellite Internet People

Right. And here's the same image compressed 75% instead of your 92%, 146KB , 48% smaller than your 278KB and looks NO different.

You got me bobby131313 ... Thank you very much.
And here's the serial number I wanted to show everyone in the image.
Roughly 79KB

Yeah sure quality drops, but a large drop? No, for our purposes it's just fine, 99% will see NO difference whatsoever. We're not building rocket ships here.

No, I'n not talking about the compression factor, I'm talking about the actual resizing of the image that was performed first.

If you take an image and resize it to 50%, it's actually 1/4th the size - 50% height and 50% width. But because it's an integral reduction, each block of 4 pixels is averaged to a single resulting pixel.

At a non-integral resize, there is high order maths applied to the reduction, including fractions of pixels and that reduces... maybe quality is the wrong word... edge sharpeness.

In the printing industry I been in forever, if I received a bad image file, no matter the size or resolution, if it is bad to start with, it usually ends bad.

The bottom line.

Garbage in. Garbage out!
The same applied here, you have clear sharp contrast image, it will reduce fine without any noticeable difference.

For sure. And for most pictures when displayed as a small part of a 1920x1080 monitor the compression doesn't matter. When you try to zoom in to see details is where you do see the artifacts of all of the processing that happens.

But then, as jbuck stated earlier, you just crop out the "Zoom In" section you need from the original and post it as a separate image.
