What does HTML formatting do?
HTML formatting (beautifying) takes messy, unindented, or minified HTML and reconstructs it with consistent indentation. Each nested tag is indented one level deeper than its parent, making the document structure immediately readable. This is especially useful when working with HTML generated by tools, CMS exports, or template engines that produce unformatted output.
Is my HTML code sent to a server?
No. All formatting and minification runs entirely in your browser using JavaScript. No data ever leaves your machine. This makes it safe to use with proprietary templates, internal tooling HTML, or any code that contains sensitive class names or content.
What is the difference between beautify and minify?
Beautifying (formatting) adds indentation and newlines to make HTML readable by humans — useful during development and code review. Minifying does the opposite: it removes all unnecessary whitespace, blank lines, and comments to produce the smallest possible HTML file. Minified HTML is used in production to reduce page load time and bandwidth.
When should I use the HTML minifier?
Use minification when deploying static HTML files to production, especially for landing pages, email templates, or any HTML that is served directly without a build pipeline that handles minification automatically. Reducing HTML size — even by 20–40% — can improve Time to First Byte (TTFB) and Largest Contentful Paint (LCP) scores.
