Convert Text to PDF using Java

A text document in TXT format contains plain text in the form of lines. TXT files are the simplest and easiest way to store plain text without any formatting. We can easily create, open, and edit TXT files in any text editor or word processing application. In certain cases, we may need to convert the text into read-only formats such as PDF. In this article, we will learn how to convert a text to PDF programmatically using Java.

The following topics shall be covered in this article:

Text to PDF Converter - Java API

For converting text to PDF, we will be using the Aspose.Words for Java API. It allows creating and manipulating MS Word documents. Moreover, it lets you convert MS Word and text documents to various other file formats.

The Document class of the API represents a document loaded in a defined format. It is a root node of a tree that contains all other nodes of the document. The save() method of this class saves the document in a specified file format. The TxtLoadOptions class of the API allows specifying additional options when loading the text document into a Document object.

Please either download the JAR of the API or add the following pom.xml configuration in a Maven-based Java application.

  2. Next, specify various TXT load options.
  3. After that, load the text file using the Document class with the TxtLoadOptions object.
  4. Save as PDF using the Document.save() method. It takes the output file path as an argument.
