• ⚙️ Configurable - Control line length and selectively disable minification features
• 🔧 Framework Support - Special handling for Knockout.js, Angular, and other comment-dependent frameworks
• 🎯 Targeted Minification - Choose what to minify: HTML comments, JavaScript comments, or Knockout comments
• 🔄 CI/CD Ready - Easy integration with MSBuild and build pipelines

1. Download the latest release from the releases page
2. Extract the HtmlMinifier.exe to your desired location
3. Add the tool to your PATH or reference it directly

Transform verbose HTML into compact, optimized code:

<h2>
    Admin Menu</h2>
<ul>
    <li>@Html.ActionLink("Edit blog entries", "List", "Admin")</li>
    <li>@Html.ActionLink("View Comments", "CommentList", "Admin")</li>
    <li>@Html.ActionLink("Clear Cache", "ClearCache", "Admin")</li>
</ul>

<h2> Admin Menu</h2><ul><li>@Html.ActionLink("Edit blog entries", "List", "Admin")</li><li>@Html.ActionLink("View Comments", "CommentList", "Admin")</li><li>@Html.ActionLink("Clear Cache", "ClearCache", "Admin")</li></ul>

Minify all HTML files in a folder (including subfolders):

HtmlMinifier.exe "C:\Folder"

Restrict the maximum number of characters per line:

HtmlMinifier.exe "C:\Folder" "60000"

For frameworks that rely on HTML comments (Angular, Knockout, etc.), preserve them:

HtmlMinifier.exe "C:\Folder" ignorehtmlcomments

Keep JavaScript comments in your code:

HtmlMinifier.exe "C:\Folder" ignorejscomments

Specifically preserve Knockout.js comments:

HtmlMinifier.exe "C:\Folder" ignoreknockoutcomments

HtmlMinifier.exe "C:\Folder\fld1" "C:\Folder\fld2"

HtmlMinifier.exe "C:\Folder\file1.html" "C:\Folder\file2.html"

Integrate HTML Minifier into your build process for automatic minification during deployment. Check out this detailed guide on using HTML Minifier with MSBuild.
