Try this. Seems pretty straight forward and appears to do an acceptable job for websites and whatnot. The one odd thing I noticed is that the compression scale seems opposite to others. In other words, in most software I have used, the lower the compression, the lower the number. Higher compression, higher number. This is the opposite. So if you want less compression (higher quality but higher size) then you need to slide the scale up more. Play around with it a little and you will see what I am referring to. But it did 10 photos with low compression in about 30 seconds. It's also freeware.
