# How to make HTML-to-PDF conversion more secure?

The version of Google Chrome releasing on 8 January 2025 removes headless functionality. If you’re using Nutrient Document Converter (formerly Muhimbi PDF Converter) or Nutrient Document Converter Services (formerly Muhimbi PDF Converter Services) on-premises applications, configured to use Chrome, this may have an impact on your HTML-to-PDF conversions. To resolve this, switch to Blink Binaries or [Chrome headless shell](https://www.nutrient.io/guides/document-converter/document-converter-services/troubleshooting/chrome-headless-shell-update.md).

Administrators can make HTML-to-PDF conversion more secure (when the Chromium-based converter is used) by automatically removing potentially malicious HTML tags. To do this, add the following entry in the configuration of the Conversion Service:

```xml

<add key="HTMLConverterFullFidelity.RemoveNodes" value="iframe, embed, object"/>

```

With the configuration above, all `<IFRAME>`, `<EMBED>`, and `<OBJECT>` HTML tags will be removed before conversion, thereby blocking any attempts to exploit security vulnerabilities tied to them.
