This is in answer to a question I was asked some time back, somewhere or other, in response to a rather derogatory comment I made regarding Microsoft Paint, the graphics program shipped with Windows. I can't for the life of me remember where the conversation took place, so I'm just hoping that the person in question follows this blog.
In M/S Paint, there is no user-adjustable quality-setting or an option to save to a better format. You get a low-quality jpg file and that's it. Doesn't matter if you're producing your own artwork from scratch or editing a super-dooper high-quality image which you've imported from elsewhere. The output will be the same. It will be a heap of crap.
Here's one I made earlier. It's a jpg file (obviously) and weighs in at 3.09 Kb. Notice the "ghosting" effect around the lettering? That's a consequence of saving an image at too low a quality setting, and is an almost sure-fire way to tell that it's been produced in M/S Paint.
For comparison, here's a jpg I created using Paint.NET (although I could have used almost any graphics program). It's the best-quality jpg setting I could get, and has a file-size of 12.2 Kb. The text still isn't exactly crisp-edged, but at least there's little of that unsightly ghosting.
Here's a png image of the same thing, which weighs in at a mere 4.5 Kb; not much more than the M/S Paint jpg, and way smaller than the "good quality" Paint.NET jpg:
And that, Gentle Reader, is why we should not use Microsoft Paint for anything. Ever.
