I have 1 question
how to convert from jfif to jpg when taking a screenshot without renaming it?
Which system and browser do you use? I am testing this now on Chrome, Firefox, and Safari, and a screenshot.jpeg is being created in each case.
It looks like a Windows issue, perhaps introduced by one of the updates. Windows saves images in browsers as JFIF instead of JPG format. Please take a look at this Reddit thread to learn how to fix it: https://www.reddit.com/r/Windows10/comments/lggspj/having_problems_with_win_10_saving_images_as_jfif/
