How to Format HTML
- Add your HTML. Paste it into the editor, upload an .html file, or click Sample to try it out.
- Pick your style. Choose 2 spaces, 4 spaces or tabs, a line length and how attributes should wrap.
- Format it. Click Beautify and the code is tidied right inside the same editor, with syntax colours and line numbers. Pasted code is formatted automatically.
- Copy or download. Copy the clean code to your clipboard or save it as an .html file.
Features
Clean Indentation
Every tag is placed on its own line with consistent indentation, so nested elements are easy to follow. Code inside pre and textarea tags is left exactly as it is.
Formats CSS and JavaScript Too
Styles inside style tags and scripts inside script tags are tidied as well, so the whole page is readable, not just the HTML.
Minify With One Click
Switch to Minify to strip comments and extra whitespace. You’ll see how much smaller the file got, which helps pages load faster.
Fast on Big Files
Formatting runs in the background, so the page never freezes. Even files with tens of thousands of lines are ready in under a second, and the editor scrolls smoothly through all of them.
Easy on the Eyes
Tags, attributes, values and comments each get their own colour, with line numbers down the side. It feels like working in a proper code editor.
Private and Offline Friendly
Your code never leaves your browser. It’s handy for client work, internal pages and anything you’d rather not paste into a random website.

Frequently Asked Questions
Is the HTML beautifier free?
Yes. Format and minify as much code as you like, with no sign up.
Does it change how my page works?
Beautifying only changes spacing and line breaks, so the page works the same. Minifying removes comments and spaces between tags, which in rare cases can change spacing between inline elements.
Is my code uploaded?
No. Formatting happens entirely in your browser. Your code is only saved locally so it’s still there if you reload the page.
Can I format PHP or template files?
You can paste them in, and the HTML parts will be formatted. Template tags are usually left as they are, but always check the result before using it.
