Format, minify, and preview HTML online
HTML Tools cleans up messy markup, shrinks it for production, and lets you preview the rendered result — all without leaving your browser.
Why use this tool
Consistent formatting
Re-indents nested tags to a clean, readable 2-space style, making markup easy to scan and debug.
Safe live preview
See exactly how your HTML renders in a sandboxed frame — scripts are disabled so it's safe to paste untrusted markup.
Production-ready minify
Strip comments and collapse whitespace to reduce page weight before deploying.
No upload, ever
Formatting, minifying, and previewing all happen locally in your browser.
