How it works
HTML Beautifier
Re-indent HTML copied from DevTools, a CMS export or a minified build. Inline <style> and <script> blocks get formatted too.
Paste or type to begin. Everything runs in your browser.
- 01
Paste HTML, drop an .html file onto the input, or load the sample.
- 02
Choose an indent and whether long lines wrap at 80 or 120 characters.
- 03
Copy the clean markup or download it as an .html file.
Good to know
- Whitespace inside <pre> and <textarea> is left alone, and inline tags like <a> and <strong> stay on the line with their text.
- It won't repair broken markup, but once the nesting is visible, an unclosed <div> is easy to spot.
FAQ
Frequently asked questions
Will it change how my page looks?
Almost never. Only whitespace between tags changes.
Does it handle email templates?
Yes. Nested tables get the same indentation, which makes them far easier to follow. To see how the email renders, use the Email HTML Previewer.
