How to Paste a picture as JPG instead of PNG

I managed to find a solution for my problem, and want to share with you guys. But it is only applicable with MS Word, since it is what I am having issues with. So basically you need to use ShareX, and set it so that the image format output is JPG. Then, MOST IMPORTANTLY, use the “save, copy image file” option from the quick task menu that popped out whenever you take a screenshot. If the menu does not pop up, set it so. Now when you paste it into MS Word, it will automatically be pasted as JPG.

Why this works is because I think MS Word only recognize the image type copied from certain source. If it doesn’t recognize the source, it will be pasted as PNG/bitmap by default. So when you setup ShareX per above steps, you are saving the pictures in your PC. Then ShareX will automatically copy from the image file itself (which Word recognize), so you can directly paste it as JPG into Word.
