Frequently asked questions
Is this HTML formatter free?
Yes, completely free, with no sign-up, no watermark, and no limit on how often you can use it.
Is my HTML uploaded anywhere?
No. All formatting happens entirely in your browser with JavaScript. Your markup is never sent to our servers, so it stays private even for confidential or internal pages.
Does it format inline CSS and JavaScript too?
Yes. As well as indenting your HTML tags, the formatter tidies the CSS inside
<style> blocks and the JavaScript inside <script> blocks, so the whole document comes out readable.Can I choose the indentation?
Yes. Switch between 2-space, 4-space, and tab indentation to match your project’s style, then copy or download the cleaned-up markup.
Does formatting change how my page renders?
No. The formatter only adds whitespace and line breaks between tags; it never rewrites your content, attributes, or structure, so the page renders exactly as before, just easier to read.
How do I host the formatted HTML?
Click Publish and your page goes live at its own HTTPS link in seconds, a fast way to share a prototype or a one-off page with no build step or server setup.
