What is an HTML formatter?
An HTML formatter takes code that is minified or poorly spaced and adds line breaks and indentation so the structure becomes visible. Nested tags line up, and the whole document is easier to scan and edit.
Formatting never touches the meaning of your page. It only rearranges whitespace, so what works before formatting still works after.
How to use this tool
- Paste your HTML.
- Click Format HTML to add clean indentation.
- Click Minify to compress it for production.
- Copy the result whenever you need it.
When to format
- After copying minified HTML from a build tool.
- When debugging a template you did not write.
- Before sharing code that others will maintain.
Format and minify are partners
Keep the readable version in your source code and minify only when you deploy. That gives you maintainable code during development and fast, small files in production.
Frequently Asked Questions
It takes HTML that is minified or badly indented and adds line breaks and indentation so the nesting is visible and the code is easy to read.
No. Formatting only changes whitespace. Tags, attributes and content stay exactly the same, so the rendered page is identical.
Click the Minify button. It removes unnecessary whitespace and comments, shrinking the file for faster loading in production.
Block tags like div, p and section are placed on their own lines, while inline tags like span stay in the flow of their line for natural reading.
The formatter needs well-formed tags to indent correctly. Unclosed or mismatched tags can confuse the indentation, so fix those first.
No. Formatting runs entirely in your browser. Your HTML never leaves your device.
