Parallel PDF Generation
Through IronPDF's support for asynchronous, multi-threaded PDF generation, parallel programming is a breeze. Through this, you can do two or more tasks at the same time, or use the Parallel.ForEach
loop as we have in this code example for PDF generation.
Steps for Parallel PDF Generation
Here is an example that demonstrates how to use Parallel.ForEach
to generate PDFs concurrently:
Explanation
ChromePdfRenderer: The first thing we need to do when using parallel PDF generation with IronPDF is to create a new
ChromePdfRenderer
instance. This gives us access to the powerful Chromium-based rendering engine and its methods for generating high-quality PDF documents from HTML strings.HTML Strings List: Next, we define our list of HTML strings, which here contains three HTML strings that we intend to convert into PDF documents.
Parallel Processing: The next step is to use
Parallel.ForEach
to process these strings concurrently. This allows the application to generate multiple PDF documents simultaneously, significantly improving performance when dealing with a large number of items—such as generating large batches of PDF documents.- Render and Save PDFs: Inside the
Parallel.ForEach
block, we call theRenderHtmlAsPdf
method. This method takes the current HTML string for each iteration through thehtmlStrings
list and converts it into a PDF document. You can then save the PDF documents or manipulate them further using IronPDF's other PDF editing features.
