How do I convert an HTML file to HTM?

Upload your HTML file to the converter, select HTM as the output format, and click Convert. The tool renames the file extension from .html to .htm while keeping all content intact. Download the converted HTM file and use it as needed.

Why convert HTML to HTM instead of keeping the .html extension?

HTML and HTM are identical in structure; only the extension differs. Converting to .htm is necessary when you're working with legacy web servers, older operating systems, or local file systems that require three-character file extensions. It ensures your pages load correctly in these environments.

Does converting HTML to HTM affect my web page's styling or interactivity?

No, the conversion only alters the file extension. All HTML tags, CSS styles, JavaScript code, and other attributes remain exactly the same. There is zero loss of data or functionality, so your page renders and behaves identically in any browser.
