Java - Convert Word to PNG, PDF, HTML, XPS, Etc.

In our daily work, we often encounter the need to convert Word documents to other formats. For example, we need to save contracts and invoices as PDF after being made in Word, and we also need to save Word documents as HTML if we want to browse them in a browser. In this article, I am going to show you how to convert Word to PNG, PDF, HTML, XPS, TXT, RTF, etc. using Spire.Doc for Java.

If you create a Maven project, you can easily import the jar in your application using the following configurations. For non-Maven projects, download the jar file from this link and add it as a dependency in your application.
