How to resolve the issue of Blink binaries (Portable Chromium) no longer being included?

Blink Binaries are no longer bundled with Nutrient Document Converter. We provide the following two workarounds:

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(opens in a new tab).

1. Installing Chrome

Install the Chrome application on the Conversion Service machine and configure the Web Service to use the Chrome application:

<!-- It's possible to use the version of the Chrome application that's installed system wide.
      This configuration only has an effect if the `HTMLConverterFullFidelity.HtmlRenderingEngine` configuration is set to `Chromium`. Accepted values include:
      * Chrome — The software will try to detect the installed instance of Chrome and will use it for converting HTML documents into PDF.
      * Leave it empty to use the default Blink engine bundled with Document Converter. -->
<add key="HTMLConverterFullFidelity.UseInstalledChromiumBrowser" value="Chrome"/>
<!-- It's possible to use a custom version of Portable Chromium stored on the local file system.
      This only has an effect if `HTMLConverterFullFidelity.HtmlRenderingEngine` is set to `Chromium` and `HTMLConverterFullFidelity.UseInstalledChromiumBrowser` is left empty.
      Enter the full path of the folder containing the custom Portable Chromium executable. -->
<add key="HTMLConverterFullFidelity.ChromiumPath" value=""/>

2. Downloading Portable Chromium

Download Portable Chromium from our website and configure the web service to use it.
