Our website offers a free transformation service based on uml2svg: http://uml2svg.sourceforge.net/online. This is the ideal approach when you wish to try uml2svg without the trouble of having to install an XSLT processor. While this solution works fine when you have only a couple of small XMI files you wish to process, when your files are large or your Internet connection is slow you will have to use the Standalone Edition. Another reason for not choosing the online edition is security. If the diagrams you wish to process are supposed to be secret for your corporation, than sending them over the Internet is not a wise decision at all.

The Online Edition of uml2svg is actually different from the Standalone Edition in only one way. It is run on our web server via a script. We have installed the Standalone Edition ourselves so that you can access it via a web interface.

The Standalone Edition is the main edition of uml2svg that you can download from: http://uml2svg.sourceforge.net/download

Although there might be multiple versions available you will usually want to download the latest. You can also chose the archiving method: Windows users will usually prefer zip files over tar.gz files that make the delight of UNIX users. There are no structural differences between the archives; just the compression method is different.

So, aside from these issues, what you need to remember is that uml2svg only comes in only one flavor: XSLT source code. And you will need an XSLT processor to make it work.
