ても構わない gives permission, like てもいい, but with more of a sense of "I don't mind": 窓を開けても構いません, "you're welcome to open the window".

構う means "to mind" or "care about", so the negative says there's nothing to mind. It's a little more formal than てもいい, which makes 構いません common at work and in shops: カードで払っても構いませんか, "is it all right if I pay by card?"

The negative version works too: 来なくても構わない, "it's fine if you don't come".

On its own, 構いません is a polite "that's fine", while 構わないで means "leave me alone" or "don't go to any trouble".
