3. Download a PDF from a URL using IronPDF

You can easily download a PDF document from a URL with just a few lines of code using IronPDF. URL to PDF conversion has a lot of applications, such as saving or sending UI designs and record-keeping to name a few. Using IronPDF's URL to PDF file conversion takes just a few seconds, as it uses the world's number one rendering engine to render HTML.

This tutorial will demonstrate IronPDF's precision and efficiency with two different websites that vary in size and complexity.

3.1. Downloading a PDF from the URL of an eCommerce Website

IronPDF can render text images and descriptions of any eCommerce website from a URL with just a few lines of code.

To perform this conversion, copy the URL of your favorite eCommerce website and execute the project with code similar to what's given below.

using IronPdf;

// Instantiate renderer
var renderer = new IronPdf.ChromePdfRenderer();

// Create a PDF from a URL or local file path
var pdf = renderer.RenderUrlAsPdf("https://www.daraz.pk/#hp-flash-sale");

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

using IronPdf;

// Instantiate renderer
var renderer = new IronPdf.ChromePdfRenderer();

// Create a PDF from a URL or local file path
var pdf = renderer.RenderUrlAsPdf("https://www.daraz.pk/#hp-flash-sale");

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

Imports IronPdf

' Instantiate renderer
Private renderer = New IronPdf.ChromePdfRenderer()

' Create a PDF from a URL or local file path
Private pdf = renderer.RenderUrlAsPdf("https://www.daraz.pk/#hp-flash-sale")

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

The output for the given sample is below. Compare this image with how it appears in a web browser:

3.2. Downloading a PDF from the URL of a Blog Website

Blog websites have a lot of small details that are important for their UI. Ideally, these details should be preserved when converting blog pages to PDFs.

The next example will present the results of converting a Wikipedia article to PDF.

A Wikipedia article in the web browser

using IronPdf;

// Instantiate renderer
var renderer = new IronPdf.ChromePdfRenderer();

// Create a PDF from a URL or local file path
var pdf = renderer.RenderUrlAsPdf("https://en.wikipedia.org/wiki/URL");

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

using IronPdf;

// Instantiate renderer
var renderer = new IronPdf.ChromePdfRenderer();

// Create a PDF from a URL or local file path
var pdf = renderer.RenderUrlAsPdf("https://en.wikipedia.org/wiki/URL");

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

Imports IronPdf

' Instantiate renderer
Private renderer = New IronPdf.ChromePdfRenderer()

' Create a PDF from a URL or local file path
Private pdf = renderer.RenderUrlAsPdf("https://en.wikipedia.org/wiki/URL")

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

The output PDF file from the Wikipedia article

When creating the PDF of blog pages, internal links should not be broken. PDFs created using IronPDF maintain all links correctly.
