In the Krita file browser, I can see them saved with little blue and white pictures beside them, but when I go to upload them to a site or even look for them in my file explorer, they're not there
You have to give us some more information before we can help you. It is very unlikely to be a bug in krita, of course, and very likely to be a problem with your Windows setup. * which version of Krita are you using, exactly? * which file format are you saving as? * do you have any security software installed other than Windows defender? * Can you check whether https://forum.kde.org/viewtopic.php?f=139&t=150612&p=402650#p402650 is the case? * can you make a screenshot of Krita's file dialog after saving and Windows Explorer of that same folder?
