Google has released a mobile version of the Google Docs viewer for Android, iPhone and iPad.

Following last week?s announcement that the Google Docs viewer supports .doc and .docx attachments, Google unveiled the mobile version of Google Docs, which is designed to help users view PDFs, .ppt, .doc and .docx files they have uploaded to their documents list, without needing to download the file.

With Google?s mobile viewer, users can switch quickly between pages and pan or zoom within a page. On their iPhone and iPad, users can pinch to zoom in or out.

Consumers can try it out by going to http://docs.google.com on their Android-powered device, iPad or iPhone and select any document in these formats that they have previously uploaded.

Here is a screengrab of the mobile version of Google Docs:

Mobile Marketer?s Dan Butcher interviewed Jonathan Rochelle, group product manager for Google Docs at Google, Mountain View, CA. Here is what he had to say:

What is Google?s strategy behind releasing a mobile version of the Google Docs viewer for Android, iPhone and iPad?
Our viewer for the desktop has made it seamless for users to view files across the Web without needing to download files and install other services to view them.

With the mobile docs viewer, we are bringing this experience to the mobile device. 

In addition to the blog post, how is Google getting the word out about the release?
Users of supported mobile devices will automatically experience the mobile viewer for themselves.

Does Google Docs enable editing using a mobile device?
As you've noticed, Google Docs products are being displayed on the iPad in their mobile versions. We made individual decisions for each of Google's Web applications using the iPad Simulator, and served the version we think works best.

We chose mobile for Docs because Google Docs uses features of a browser that the iPad's version of Safari doesn't support.

We are continually working on better ways to display our Web apps on the iPad and other devices, and if you need any help using the mobile version of Google Docs, you can click the Help link in the corner of the screen.
