If you have a PDF document that you want to put on a web page, the most common scenario would be that you post it to the web in the PDF format, add a link to the document on a webpage, and allow people to download that document. A common example of this would be a medical practice that publishes their patient forms to their website and asks those patients to download the form, print it, complete it, and return it when they visit the office. This is different than having an online form that can be filled out in the browser. This is just a PDF document that they can download.
Sometimes you may want to do more with your PDFs. Instead of simply making them available for download, you may want to convert that content into a real HTML web page. To do this, you could obviously hand code the content from scratch and build the web pages manually. If you do not know HTML/CSS, however, this is unlikely to be possible for you.
Thankfully, there are some other (much easier) options if you want to turn PDFs into simple web pages (note that this process will not allow you to turn a PDF of an E-commerce site design into an actual working webpage complete with a shopping cart system - this process is for basic, informational pages only). The PDF to HTML converters covered in this article will help you turn PDF files into HTML web pages.
