+It accepts `POST` requests with a `multipart/form-data` Content-Type.

+
+This endpoint does not accept an `index.html` file nor assets files but a form field
+named `remoteURL` instead. Otherwise, URL conversions work the same as HTML conversions.

+                <p>Gotenberg provides the endpoint <code>/convert/url</code> for remote URL conversions.</p>
