There are plenty of sites around that
perform some useful file conversion, such as transforming HTML code
into a PDF document. Online Converter goes a little further, though,
by providing tools to transform audio, video and image files, documents
and eBooks from one format into another.
There's excellent format support, so for instance the site can
handle 11 image file types, and 9 eBook variants. And the Video
module is able to output movies targeted at particular devices,
including the iPhone, iPod, Nintendo DS, PS3, PSP, Wii, and XBOX360.
