Most of these DOT to PNG converters are also helpful to view the DOT graph as SVG document but you can’t save DOT file to SVG document.

Apart from DOT to PNG conversion, these websites also help to edit the content of DOT file to modify its output and then save that content to the clipboard. After that, you will be able to create a new DOT file by pasting the clipboard content to some text editor and then save that file as *.doc or *.gv.
