RoundPic. A awesome, minimalistic service that makes a task extremely simple.
We all need to round off the corners on some pics every now and then to make them look good for the internets, but before we always to go into Paint.Net, photoshop, or the GIMP. Introducing RoundPic, it just rounds off the corners of a picture that you upload or link to. It also lets you resize, change quality, choose the corners you want rounded, pick the size of the roundness, and choose a background color (or transparent png). This little site has made my life .82% easier and therefor I suggest everyone to use it.
