Beautify, format and minify HTML instantly — free, private, runs in your browser
Copy any HTML — from a file, CMS output, email template, or browser DevTools — and paste into the input.
Select indent size (2 spaces, 4 spaces, or tab). Optionally remove HTML comments or collapse empty lines.
Click Format to beautify with proper indentation. Click Minify to compress for production — removes whitespace and comments.
HTML emails are often generated by tools and have no indentation. Beautify to edit them or understand their structure.
WordPress, Shopify, and other CMS platforms often output unformatted HTML. Format it for editing or debugging.
Minify HTML before deploying to reduce file size, remove developer comments, and improve page load speed.
Hard-to-read HTML from a browser DevTools copy? Format it to understand tag nesting and find issues quickly.
An HTML formatter adds consistent indentation and line breaks to HTML code, making the tag hierarchy easy to read. It shows visually how elements are nested — block elements on separate lines, child elements indented relative to parents.
Beautifying adds whitespace and newlines for human readability. Minifying removes all unnecessary whitespace, comments, and line breaks to produce the smallest HTML file — used in production to improve load speed.
Yes. All formatting runs in your browser — no data is sent to a server. Safe for internal templates, proprietary code, and staging site HTML.
Press Shift+Alt+F (Windows) or Shift+Option+F (Mac) to format the current file. Install the Prettier extension for consistent HTML formatting with configurable options like tab size and print width.
Use the html-minifier-terser package: npx html-minifier-terser --collapse-whitespace --remove-comments input.html. For build pipelines, integrate with Webpack or Vite.
