HTML to PDF

In digital workflows, directly printing or archiving rich HTML web pages or large HTML files is often inefficient and ineffective. Foxit PDF SDK provides powerful The API interface is designed to solve this problem and support the efficient and accurate conversion of online web pages or local HTML files to PDF. Documents are widely used in invoices, reports and other scenarios to simplify printing and long-term archiving processes. More importantly, during the conversion process, Foxit PDF SDK can intelligently create and add PDF tags significantly improve the semantics and accessibility of PDF documents.

Core advantages:

• Excellent compatibility: Full support for HTML5, CSS3 and JavaScript, ensuring the accuracy and integrity of the conversion results, and restoring the visual effects and data structure of the original web page to the greatest extent.
• Cross-platform support: Starting from version 7.6, HTML to PDF conversion is supported on the Linux platform to meet cross-platform development needs. Please note that in Linux environment, HTML to The PDF engine depends on libnss 3.22 version.
• Flexible data processing: Since version 8.1, it supports outputting HTML2PDF converted files in the form of file streams, making it easier for developers to integrate into various real-time data processing applications.

Getting started:

See the detailed HTML to PDF example configuration and run guide to learn the setup steps and run the sample so you can get up to speed quickly.

Code examples:

The following code demonstrates how to call the relevant APIs to convert HTML to PDF.

Read HTML from a stream and convert it to PDF

The following uses Java as an example:

1. Define a FileRead class that extends FileReaderCallback to read HTML data from a stream or memory, and a FileWriter class that extends FileWriterCallback for file output. For implementations of FileRead and FileWriter, see the html2pdf demo in the \examples\simple_demo\html2pdf folder.
2. Read HTML data from the stream and configure resources related to the source HTML.
3. Call com.foxit.sdk.addon.conversion.Convert.fromHTML to convert the HTML to a PDF file.
