Website that can optimize my images

[windows]

Is there a site that I can take images on my hard drive and somehow "optimize" - reduce the size of the file so I can put it on a webpage and it's not so big? I have MS PhotoDraw but heck, it's 120mb install and I don't want to do that.<br />
<br />
In lieu of that, a program I could Download <!--more--> that's a whole lot smaller than 120mb.<!--content-->Something like this? <!-- m --><a class="postlink" href="http://www.netmechanic.com/GIFBot/optimize-graphic.htm">http://www.netmechanic.com/GIFBot/optimize-graphic.htm</a><!-- m --><br />
