How can I save a png (or anything really) image as a dds one?

Does anyone know a (free) way to do this? I tried getting a GIMP plug in but it didn't even work.

I've looked it up on google

Maybe you can use an online convertor? I found this: http://online-converting.com/image/convert2dds/

I saw this do, but it wouldn't accept any images for whatever reason.

Paint.NET lets you do it. You can find it on CNET or at www.getpaint.net/download.html
