When 50KB is the right target

50KB is a sweet spot for upload forms and web use. It is small enough to load instantly and satisfy strict form limits, but slightly more generous than 40KB or 20KB, so portraits and ID photos keep a bit more detail.

If a form gives you a 50KB cap, target just under it (the tool aims at or below 50KB). If the result looks too soft, reduce the image's dimensions first with the resize tool, then compress; smaller dimensions reach 50KB with less visible quality loss than a large image squeezed hard.
