JPEG and PDF are the two most widely used file formats at the current point in time. PNG and JPEG are raster image files whereas, PDF is based on vector files. However, you need to convert JPEG to PDF as the business requirements change. Therefore, we will use this enterprise-level PDF generator library to achieve the JPEG to PDF conversion. Moreover, it enables you to programmatically parse, process, and convert popular image file formats to PDF files. Let’s write the code snippet to convert JPEG to PDF using Java API.

We will cover the following sections:

  3. Instantiate an instance of the Image class.
  4. Load sample JPEG image file by calling the setFile method.
  5. Invoke the setFixWidth method to set the width of the image.
  6. Call the setFixHeight method to set the height of the image.
  7. Initialize the constructor of the TextFragment class and call the setTitle method to set the title of the JPEG image.
  8. setApplyResolution method sets a boolean value that indicates whether the image use resolution during generation.
  9. setBlackWhite method sets a boolean value that indicates whether the image is forced to be black-and-white.
  10. Invoke the getParagraphs().add(image) method to add the JPEG image to the page.
  11. Call the save method to save the output as a PDF document.

Copy & paste the following code into your main file:
