Some projects use ZIP packages for more efficient storage and transfer. If a user wants to render an HTML file contained within a ZIP, there's no need to manually extract its contents. With IronPDF, you can render the entire project including all assets directly from the ZIP file. In this article, we’ll demonstrate how to convert an HTML ZIP package into a PDF with ease.

Convert HTML ZIP File to PDF Example

Below is an example of utilizing the RenderZipFileAsPdf method to convert the HTML ZIP file into a PDF. The RenderZipFileAsPdf method takes in two parameters: the path to the ZIP file and the HTML file name within the ZIP file.

After converting it, we then save the PDF as output.pdf.

Input File

This is the htmlSample.html HTML file that the code renders:

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Sample HTML with External CSS and JS</title>
  <!-- Link to External CSS -->
  <link rel="stylesheet" href="style.css">
</head>
<body>
  <div class="container">
    <h1>Welcome to the Sample Page!</h1>
    <p id="greeting">Click the button to change the background color and greeting text.</p>
    <button id="changeButton">Change Background</button>
  </div>

  <!-- Link to External JavaScript -->
  <script src="script.js"></script>
</body>
</html>

Here's a quick preview on how it looks on a Chromium browser.

ChromePdfRenderer renderer = new ChromePdfRenderer();

PdfDocument pdf = renderer.RenderZipFileAsPdf("htmlSample.zip", @"htmlSample.html");

pdf.SaveAs("output.pdf");

Dim renderer As New ChromePdfRenderer()

Dim pdf As PdfDocument = renderer.RenderZipFileAsPdf("htmlSample.zip", "htmlSample.html")

pdf.SaveAs("output.pdf")

$vbLabelText $csharpLabel
