Steps to convert HTML to Image using Java RESTful Service

  1. Import the namespaces Aspose.HTML.Cloud.Sdk and Aspose.HTML.Cloud.Sdk.Conversion for using desired classes and methods
  2. Create an object of the HtmlApi class and set the Client ID and secret
  3. Instantiate an object of the ConverterBuilder class and set values for the from local file and to local file properties
  4. Invoke the ConvertAsync() with the above builder properties to perform the conversion

These steps summarize the process to change a file format from HTML to JPG using Java REST Interface. Import the namespaces for the required classes and methods, create an instance of the HtmlApi with client ID and secret, and get the ConvertApi object from it. Create an object of the ConverterBuilder class, set the local or cloud storage references for the input and output files, and call the ConvertAsync() method in the API to convert the file according to the configuration in the ConverterBuilder object.

Code to convert HTML to JPG using Java API

The sample code illustrates how to generate an image from HTML using the Java Low‑Code API. You can retrieve the source files from Cloud storage if they’re already uploaded, or use files stored locally. Additionally, you can mix and match—reading HTML from the cloud while writing the JPEG to a local disk, or vice versa.

This guide has shown you how to convert HTML into a JPEG image using the Java REST API. When you’re ready to turn an HTML file into Markdown, see our companion article on Convert HTML to Markdown using Java REST API.
