This tutorial demonstrates how to convert HTML to PDF using the Java REST API. You’ll discover how to automate the transformation of an HTML document into a PDF with the Java Low Code API by leveraging the Java‑based Cloud SDK, and you’ll learn to apply a range of options to fine‑tune the output PDF.
Prerequisite
- Create an account and get API credentials for converting the HTML file to a PDF file
- Download the Aspose.HTML Cloud SDK for Java from its repository: https://github.com/aspose-html-cloud/aspose-html-cloud-java
- Set up a Java project that includes the SDK above
Steps to Convert HTML File to PDF using Java RESTful Service
- Start by adding the necessary libraries from Aspose.HTML Cloud so your project can work with HTML and file conversion
- Use your Client ID and Secret to securely connect to Aspose Cloud services and access its conversion features with the HtmlApi object
- Grab the conversion API from your initialized object so you can start turning HTML into other formats
- Declare the PDFConversionOptions and set the page size and margins by setting the width, height, and all four margins to shape your final PDF file
- Run the conversion with the ConvertAsync by giving it your source HTML file and telling it where to save the resulting PDF
These steps summarize the process for converting an HTM file to PDF using Java Low Code API. First, you set up access to Aspose.HTML Cloud by adding the appropriate libraries, logging in with your credentials, and getting the classes/modules that handle conversions. Then you choose how you want the PDF to generate, its size and margins—and invoke the API to turn your HTML file into a PDF.
Code to Transform HTML to PDF using Java REST API
This example illustrates how to convert an HTML document to PDF using the Java‑based API. Keep in mind that every setting in the PDFConversionOptions object is optional—simply omit any you don’t need and the defaults will be applied. All numeric values are expressed in inches.
In this guide we walked through extracting a table from an Excel workbook and saving it as an HTML file. If you also need to transform Excel data into JSON, be sure to check out the related article on Convert HTML to DOCX using Java REST API.
