While PDF files are suitable for printing and publishing, not all types of documents are suitable for this format. For example, documents containing complex charts and graphs may not render well in PDF. HTML files, on the other hand, can be read and displayed on any computer that can run a browser. In addition, HTML has the advantages of occupying less server resources and being easily indexed by search engines. So, in this article we will explain how to convert a PDF document to HTML format through a Java application. The following are the specific steps and methods I compiled, and provide the Java code as a reference.
## Programming Environment 
**Method 1:**
Introduced manually. Download Free Spire.PDF for Java locally, unzip it, and find the Spire.PDF.jar file in the lib folder. Open the following interface in IDEA, and import the jar file in the local path into the Java program:
