HBmarkdown For Editors lets you upload any Markdown (.md) file directly into a WordPress post or page and converts it into properly formatted content — no copy-pasting, no third-party services, no fuss.
Works with both the Classic Editor (TinyMCE) and the Block Editor (Gutenberg).
<h4>How it works</h4>
In the Classic Editor, an Import Markdown button appears right next to the Add Media button. Click it, pick your .md file (or drag and drop), and the content is converted and inserted instantly.
In the Block Editor, an Import Markdown panel is available in the sidebar.
<h4>Key Features</h4>
<ul>
<li>Next to Add Media — the Classic Editor button lives exactly where you expect it, in the media button row</li>
<li>Modal file importer — sleek popup with drag-and-drop support and live status feedback</li>
<li>Auto post title — if your Markdown file has a <code>title:</code> or <code>Title:</code> field in its frontmatter, the post title is filled in automatically</li>
<li>Block-aware conversion — outputs native Gutenberg block markup (wp:paragraph, wp:heading, wp:table, etc.) when Gutenberg is active</li>
<li>Pure PHP parser — zero external dependencies, no Composer, no npm, no build step; runs on any shared host</li>
<li>Full Markdown support — headings (ATX + Setext), bold, italic, strikethrough, inline and fenced code blocks, ordered/unordered lists, GFM tables, blockquotes, images, links, horizontal rules</li>
<li>Role-based access — choose which user roles can import Markdown via the settings page</li>
<li>Configurable file size limit — set the maximum .md file size in KB</li>
<li>Zero front-end footprint — assets are only loaded on post/page edit screens</li>
</ul>
<h4>Supported Markdown Syntax</h4>
<ul>
<li>ATX headings (<code># H1</code> through <code>###### H6</code>) and Setext headings</li>
<li>Bold, italic, ~~strikethrough~~</li>
<li>Inline code and fenced code blocks (with language hint)</li>
<li>Ordered and unordered lists (nested supported)</li>
<li>GFM tables</li>
<li>Blockquotes</li>
<li>Images (<code>![alt](url)</code>)</li>
<li>Hyperlinks (<code>[text](url)</code>)</li>
<li>Horizontal rules (<code>---</code>)</li>
<li>YAML frontmatter <code>title:</code> field (auto-applied to post title)</li>
</ul>
<h4>Privacy</h4>
HBmarkdown does not collect, transmit, or store any personal data. Uploaded .md files are processed entirely in server memory and discarded immediately after conversion. No data is sent to external servers.
