PDF file format makes the presentation of documents consistent across devices. However, when you need to put PDF documents on web pages, it's better to convert them to HTML files. In this way, all the content of your document can be displayed in the browser directly, with no need for downloading files. And the loading of large PDF documents takes a long time, while HTML files can be rendered in the browser very quickly. In addition, compared to PDF files, it is much easier for search engines to crawl HTML web pages to get information, which will give your website more exposure. This article will show how to convert PDF documents into HTML files in Java using Spire.PDF for Java.
