The H1 Tag Attributes Remover is a free, browser-based tool that strips unwanted, presentational, or deprecated attributes such as class, id, style, and align from HTML <h1> heading elements, producing clean, standard-compliant markup.
Paste your <h1> tag below, specify the attributes to remove, and click Remove.
The <h1> tag is the most important heading on a page for both SEO and accessibility it tells search engines and screen readers what the page is about. Extra attributes like inline style or the obsolete align attribute add no semantic value and can even hurt code quality. This tool removes them in one click.
The tool safely parses your HTML, lets you choose exactly which attributes to remove (or use * to strip all), and protects important attributes like role and aria-* through a preserve list. It never touches the heading text itself only the attributes on the opening tag. Everything runs locally in your browser: no uploads, no installation, full privacy. A one-click Copybutton and a Clear reset make it fast to use repeatedly.
