About HTML Beautify / Minify

Pretty-print an HTML document or fragment with 2, 4 or 8 spaces or tabs, including inline <style> and <script> blocks, or minify it. Beautify uses js-beautify; minify removes comments (except conditional comments), collapses whitespace between block elements and inside tags, and minifies inline CSS and JavaScript, while leaving <pre> and <textarea> content as-is.

Common uses

Make minified or generated HTML readable before inspecting or editing it.
Normalize indentation of a template before committing it.
Compact a static HTML snippet or email template to reduce its size.
Format markup copied from browser DevTools.
