About HTML Tools
This category offers 43 tools for writing, cleaning and converting HTML. The HTML Formatter indents messy markup, the HTML Minifier shrinks it for production, and the HTML Validator points out unclosed tags and other common mistakes. Converters turn HTML into plain text, Markdown or JSX for React, and Markdown to HTML goes the other way.
Generators write the snippets that are easy to get slightly wrong: meta and Open Graph tags for sharing previews, JSON-LD structured data, responsive srcset attributes, iframes, forms, tables and accessible details accordions. Most show a live preview next to the code. Parsing is done by a tokenizer written for the browser rather than by loading your markup into the page, so scripts inside pasted HTML never run. The Meta Tag Generator is a quick place to start when launching a new page.
