pdf.SaveAs("async_example.pdf");

using IronPdf;

// Instantiate Renderer
var renderer = new ChromePdfRenderer();

// All IronPdf Rendering methods have Async equivalents
var pdf = await renderer.RenderHtmlAsPdfAsync("<h1>Html with CSS and Images</h1>");

// Export to a file or Stream
pdf.SaveAs("async_example.pdf");

Imports IronPdf

' Instantiate Renderer
Dim renderer = New ChromePdfRenderer()

' All IronPdf Rendering methods have Async equivalents
Dim pdf = Await renderer.RenderHtmlAsPdfAsync("<h1>Html with CSS and Images</h1>")

' Export to a file or Stream
pdf.SaveAs("async_example.pdf")
