Document Conversions in SharePoint 2010

In SharePoint environment, Document conversion i.e. converting one document from one format to another can be possible.
This is achieved by the following two services.

The primary infrastructure for conversions includes two components:

•The Document Conversions Load Balancer, which manages the availability of document converters.
•The Document Conversions Launcher, which launches document conversions on an application server.

And the following PowerShell command can be used to activate it at the web application level.

$app = Get-SPWebApplication https://mysites/sites
$app.DocumentConversionsEnabled = 1
$app.Update()
