Convert HTML to PDF Example
Here we have an example of IronPDF renderig HTML file into a PDF by using the RenderHtmlFileAsPdf()
method. The parameter is a filepath to a local HTML file.
This method has the advantage of allowing the developer the opportunity to test the HTML content in a browser during development. They can, in particular, test the fidelity in rendering. We recommend Chrome, as it is the web browser on which IronPDF's rendering engine is based.
If it looks right in Chrome, then it will be pixel-perfect in IronPDF as well.
Input File
