Zoho Viewer Updates

Posted by Posted on by

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.

If you are using our bulk upload option, you will notice that selecting multiple files for upload has now been made easier. In the file chooser, you will be presented with a filtered list of files supported by Zoho Viewer and you will be able to select multiple files using the ctrl/shift keys. We have also added an option “Email these links” which will be visible once you upload files in bulk. You can email the links to yourselves for your future reference.

The wpd file format is supported in our Viewer APIs as well. Here is the full list of supported file formats:

Presentation Viewer and API Enhancements in Zoho Viewer

Posted by Posted on by

Here are some of the recent updates in Zoho Viewer:

1. Presentation Viewer

The presentation viewer has been enhanced. We now use Adobe Flash to display the presentations. Here are some highlights:

  • No more fixed size. The slides now occupy the maximum space available on your browser window. 
  • The slide navigation bar has been enhanced and is now similar to Zoho Show.
  • You can click on the Play icon to automatically run through the presentation (Auto Play) with 5 secs pause on each slide.
  • Of course, you have the already existing SlideShow link and a new icon to view it in full screen.
  • The upload and processing of presentations is now much faster.

Here is a screenshot of the new presentation viewer. Click on the image to open the online presentation.

Next, we are working on the PDF viewer. Online viewing of PDF files is one area where Zoho Viewer is lacking and we are fixing that.

2. API options

We now
provide options to hide the links such as Edit, Print, Save, etc while
using our Viewer API to display private documents stored in your
servers. Refer
for more information on the new options. Look out for the “displaylinks”
and “linkoptions” parameters. You will also notice a new “skey” parameter.
This is required if you want to send the document and bring up the viewer
securely over HTTPS.

3. Edit option now available for docx, xlsx and ppt files

We now display the Edit link for uploaded docx, xlsx and ppt files in addition to the already supported formats. Editing such files will open up the editors of Zoho Writer, Zoho Sheet and Zoho Show respectively. You can edit online and save (export) them to your system in various formats. Editing of pptx files will be available in a future version.

Let us know how you are using Zoho Viewer and what you will like to see in it. Send us your valuable feedback to

Zoho Viewer + Google Translate = Document Translation

Posted by Posted on by

I saw a tweet from Ken Huang recently and found it interesting.

Zoho Viewer + Google Translate =

is very cool. If you have document you want to quickly view, Zoho Viewer works perfectly well. It is like TinyURL for documents. But in cases where the content of the document is in a
different language, you can upload the document to Zoho Viewer and input
that URL in Google Translate to convert the contents of the document to
any language.

Here is a Zoho Writer document in Zoho Viewer and here is the translated version in Japanese.

Thanks for the tip Ken.
