HTML to XHTML – Convert HTML to XHTML Online

What is HTML to XHTML

HTML to XHTML is a free online converter that transforms HTML into XHTML 1.1-style markup, including the appropriate doctype, using a well-formed serialization process. It provides a simple way to convert HTML to XHTML when you need more structured, XML-style markup.

This HTML XHTML converter is useful for developers and website owners working with systems that expect properly closed tags and XHTML-style xmlns conventions. It can also help normalize HTML fragments before they are used in an XML-based workflow.

The tool does not validate the generated markup against an XHTML DTD. If your project requires strict XHTML conformance, always confirm the requirements of your target system and validate the final output separately.

How to Use HTML to XHTML

Step 1: Add HTML

Paste your HTML code into the converter, import an HTML file, use the provided sample, or fetch HTML from a public URL.

Step 2: Convert

Generate XHTML-style output from your HTML markup. The converter processes the input and creates a more structured XHTML representation.

Step 3: Copy or Download

Copy the generated markup or download the result for use in systems and workflows that expect XHTML-style closed tags.
