Convert Markdown to Clean HTML with Str::markdown()

Use Str::markdown() to convert GitHub Flavored Markdown into secure, sanitized HTML using CommonMark under the hood.

Rendering user comments, documentation pages, or blog post content written in Markdown traditionally required installing third-party parser packages.

Laravel includes CommonMark natively via Str::markdown().

Basic Markdown Conversion

use Illuminate\Support\Str;

$markdown = "### Welcome
This is **bold** and *italic*.";

$html = Str::markdown($markdown);
// Output: "<h3>Welcome</h3>
<p>This is <strong>bold</strong> and <em>italic</em>.</p>
"

Using Fluent String Syntax

$html = str($post->body_markdown)->markdown();

Rendering in Blade

In Blade templates, use raw output tags to display the compiled HTML:

<article class="prose">
    {!! str($post->content)->markdown([
        'html_input' => 'strip', // Strips raw unsafe HTML tags for security
        'allow_unsafe_links' => false,
    ]) !!}
</article>

Summary

• Powered by the robust league/commonmark parser.
• Supports security options to strip unsafe raw HTML and malicious JavaScript links.
• Available as a static method (Str::markdown) and fluent string helper (str()->markdown()).
