We made a few changes to the Zoho Viewer home page in the last couple of months. The main change is that you can now view a document without publishing it to a URL. This is quite useful when you want to view a private document without publishing it and you don't have the appropriate software on your computer. However, if you want to publish a document to a URL, you can still do so by using the "Publish this document" setting. There is also a separate form to view a document file already available on a public URL. In this case, the Zoho Viewer URL of this document will be available as long as the file resides on the original URL.
