PDF.js will let you render the PDF to a canvas. Then you can do something like: var img = new Image(); img.src = pdfCanvas.toDataURL(); I've been very impressed with PDF.js. I love letting the client's browser do as much of the work for me as possible.

In this quick article, we’ll focus on doing programmatic conversion between PDF files and other formats in Java. More specifically, we’ll describe how to save PDFs as image files, such as PNG or JPEG, convert PDFs to Microsoft Word documents, export as an HTML, and extract the texts, by using multiple Java open-source libraries.
The first library we’ll look at is Pdf2Dom. Let’s start with the Maven dependencies we need to add to our project: We’re going to use the first dependency to load the selected PDF file. The second dependency is responsible for the conversion itself. The latest versions can be found here: pdfbox-tools and pdf2dom. What’s more, we’ll use iText to ext...
To work with HTML files we’ll use Pdf2Dom – a PDF parser that converts the documents to an HTML DOMrepresentation. The obtained DOM tree can then be then serialized to an HTML file or further processed. To convert PDF to HTML, we need to use XMLWorker, library that is provided by iText.
There are many ways of converting PDF files to an image. One of the most popular solutions is named Apache PDFBox. This library is an open source Java tool for working with PDF documents. For image to PDF conversion, we’ll use iTextagain.
To extract the raw text out of a PDF file, we’ll also use Apache PDFBox again. For text to PDF conversion, we are going to use iText.
Creating PDF file from Word document is not easy, and we’ll not cover this topic here. We recommend 3rd party libraries to do it, like jWordConvert. To create Microsoft Word file from a PDF, we’ll need two libraries. Both libraries are open source. The first one is iText and it is used to extract the text from a PDF file. The second one is POI and ...
In previous sections, we described open source libraries. There are few more libraries worth notice, but they are paid: 1. jPDFImages– jPDFImages can create images from pages in a PDF document and export them as JPEG, TIFF, or PNG images. 2. JPEDAL– JPedal is an actively developed and very capable native Java PDF library SDK used for printing, view...
To convert a Docx file to a PDF document, we’ll need the Apache POI library to read the Word document and the iText library to generate the PDF. Here’s some simple code that reads a Docx file and writes its content to a PDF file: First, we create an InputStream object to read the Docx file. The XWPFDocument class helps to represent the Docx file in...
In this article, we discussed the ways to convert PDF files to and from various formats. As always, the source code for the examples is available over on GitHub.
PDF.js heavily relies on the use of Promises. If promises are new to you, it's recommended you become familiar with them before continuing on. This tutorial shows how PDF.js can be used as a library in a web browser. examples/ provides more examples, including usage in Node.js (at examples/node/).
