Implementation Guide

Minification of HTML Documents

Minifying HTML reduces file size and improves load times, making it a crucial step for web optimization.

Step 1: Define Output Directory

Start by specifying where your minified files will be saved:

string outputDirectory = @"YOUR_OUTPUT_DIRECTORY/";
string pageFilePathFormat = Path.Combine(outputDirectory, "page_{0}.html");

Step 2: Initialize Viewer with Minification Option

Load the document and configure HTML view options to enable minification:

using (Viewer viewer = new Viewer(@"YOUR_DOCUMENT_DIRECTORY/SAMPLE_DOCX"))
{
    HtmlViewOptions options = HtmlViewOptions.ForEmbeddedResources(pageFilePathFormat);
    options.Minify = true; // Enable HTML minification
    
    viewer.View(options);  // Render the document with minification
}

In this setup:

  • HtmlViewOptions configures how documents are rendered.
  • Setting options.Minify = true activates HTML minification.
