HTML tools for writing, checking and converting markup

HTML is the foundation of every web page and HTML email, and it travels between many systems: CMS editors, React components, template engines, forums and documentation. These HTML tools help you tidy markup, see how it renders, check it for errors and convert it into the format the next system needs.

Pick the tool for your task

Escaping and entity tools handle special characters, BBCode converters bridge forum content, and the responsive website tester shows a finished page at phone, tablet and desktop widths.

Example workflows

Publishing a Word document on a website: convert the .docx to HTML, tidy it with the formatter, preview it, and paste it into your CMS's source view. Clean semantic markup inherits your site's styles instead of fighting them.

Turning a design mockup into a React component: format the exported HTML, convert it to JSX, then replace repeated blocks with loops and hard-coded text with props.

Checking a page before launch: generate meta tags, validate the markup, then look at the page on several screen sizes.

HTML for email

Email clients support only a subset of HTML and CSS. Layouts are still built with tables and inline styles, and many clients ignore style blocks, web fonts and modern layout properties. Generate table markup with the table generator, preview the template in the HTML viewer, and always send a test message to real inboxes before a campaign.

HTML tips

  • Use semantic elements (header, nav, main, article, footer) and a logical heading order for accessibility and search engines.
  • Give every meaningful image an alt text.
  • Escape user-provided text before inserting it into HTML to prevent cross-site scripting.
  • Previews run in a sandboxed frame, so you can inspect unfamiliar HTML safely.

Frequently asked questions

How do I view HTML code as a web page?
Paste the code into the HTML viewer. It renders the markup in a sandboxed frame, including CSS and JavaScript contained in the document.
What is the difference between formatting and minifying HTML?
Formatting adds indentation and line breaks so people can read the code. Minifying removes unnecessary whitespace and comments to make the file smaller for browsers.
Can I convert HTML to React?
Yes. The HTML to JSX converter renames attributes like class and for, turns inline styles into objects and closes void elements so the markup works in React components.
How do I extract text from HTML?
Use HTML to text for readable plain text with paragraphs and lists preserved, or HTML to Markdown if you want to keep headings, links and emphasis.
