Code Example: Set PDF to Grayscale

import {PdfDocument} from "@ironsoftware/ironpdf"; (async () => { // Configure render options const renderOptions = { // Set color to grayscale grayScale: true, }; const pdf = await PdfDocument.fromHtml("my-content.html", { renderOptions }); // Export the PDF document await pdf.saveAs("my-content.pdf"); })();

Set to Grayscale

Converting a colored PDF document to grayscale can offer several advantages, such as removing the consideration of color and focusing solely on color intensity.

The feature to generate grayscale PDFs is only available when converting HTML to PDF with IronPDF's HTML to PDF Conversion Feature. You can apply a rendering option that includes a grayScale property, which can be set to true or false. Setting this property to true will generate a grayscale PDF instead of a colored one.

Below is a sample code snippet demonstrating how to convert an HTML file to a grayscale PDF using IronPDF in C#:

Explanation of the Code

Using IronPdf: Include the IronPdf library to access PDF rendering functionalities.
HtmlToPdf Renderer Initialization: Create an instance of the HtmlToPdf class, which facilitates the HTML to PDF conversion process.
Setting Render Options: Define the rendering options through the PdfPrintOptions class. The key property here is GrayScale, which, when set to true, ensures that the resulting PDF is rendered in grayscale.
Rendering HTML to PDF: Use RenderHtmlAsPdf to convert HTML content into a PDF document.
Saving the PDF: The resulting grayscale PDF is saved to the specified file path "output.pdf".
Console Notification: Display a message on the console to inform the user that the PDF has been created successfully.
