Let visitors upload an HTML file and download a CSS-faithful PDF, right from any WordPress page. The plugin renders a native form on your site and sends the file directly to the Enconvert API for conversion. No iframe, no extra tracking — just a clean form on your page.
How it works:
<ol>
<li><a href="https://enconvert.com/auth?mode=signup" title="Sign up for Enconvert" rel="nofollow ugc">Create a free Enconvert account</a>.</li>
<li>Generate a public API key (<code>pk_*</code>) on your <a href="https://enconvert.com/dashboard/api-keys" title="Open your Enconvert API keys" rel="nofollow ugc">Enconvert API keys page</a>.</li>
<li>Add your WordPress site’s domain to the key’s allowed-domains list.</li>
<li>Paste the key into the plugin settings.</li>
<li>Drop <code>[enconvert_html_to_pdf]</code> into any page, post, or shortcode block.</li>
</ol>

What the API does behind the scenes:
<ul>
<li>Accepts <code>.html</code> and <code>.htm</code> files</li>
<li>Renders via WeasyPrint, respecting your CSS <code>@page</code> rules, named page sizes, margins, headers, and footers</li>
<li>Returns a downloadable PDF in seconds</li>
<li>Supports paginated output with named sizes (A0–A6, B0–B5, Letter, Legal, Tabloid, Ledger) or custom dimensions</li>
</ul>
Free tier available — 100 monthly conversions, no credit card. Paid tiers raise the limit and increase the max file size.
<h3>Third-Party Service</h3>
This plugin sends visitor-uploaded files directly from the visitor’s browser to the Enconvert API:
<ul>
<li><code>https://api.enconvert.com</code> — receives the HTML file and returns a presigned URL for the PDF download.</li>
</ul>
The visitor’s browser sends an <code>X-API-Key</code> header containing the public API key configured in plugin settings. The API validates the key and the requesting domain (the page’s origin) before accepting the conversion. Your WordPress server is not involved in the conversion request.
<ul>
