IronPdf.UpdatedChrome for Faster HTML Rendering
When HTML-to-PDF rendering is slow, particularly on modern or complex pages, switching to the IronPdf.UpdatedChrome package can cut render time noticeably. It ships a newer, better-optimized Chromium engine than the standard package.
Why It Renders Faster
The difference comes down to the Chromium version each package bundles:
- Standard IronPdf: Chromium engine
109.1.18.0. - IronPdf.UpdatedChrome: Chromium engine
131.2.7.0.
The newer engine is built to process today's web standards efficiently. Modern pages tend to carry complex layouts, heavy CSS styling, large and deeply nested DOM trees, and client-side JavaScript rendering, and the updated Chromium handles that structure far more efficiently than the older one.
When to Use It
Reach for IronPdf.UpdatedChrome when the standard package is rendering slowly on demanding input. It tends to help in these cases:
- PDFs that take several minutes to render.
- HTML with deeply nested elements.
- Pages built on modern CSS frameworks such as Bootstrap or Tailwind.
- JavaScript-heavy pages.
- Layouts that are complex or generated dynamically.
How to Test the Difference
You can predict the gain before swapping packages by checking how Chrome itself handles the page. The engine in IronPdf.UpdatedChrome behaves much like Chrome's own print preview.
- Open the page in Google Chrome. Load your HTML file directly in the browser.
- Open Print Preview. Press
Ctrl + Pand watch how quickly the preview renders. - Compare the speed. If Chrome renders the page quickly,
IronPdf.UpdatedChromewill typically perform at a similar speed.
