HTML beautifier
如何使用HTML beautifier
HTML beautifier reformats HTML markup with consistent line breaks and indentation, using 1 to 8 spaces per level. The markup is parsed as text and never rendered or executed, so scripts in it do not run. Attribute quotes are normalized to double quotes, and invalid markup returns a parser error instead of output.
- Paste the source into the input editor, or load the built-in example.
- Set indent spaces.
- Run html beautifier, review the output, then use the available copy or download controls.

常見問題
Does the HTML beautifier run scripts in my page?
No. The HTML is parsed as text and printed back with new indentation. Nothing is rendered, loaded or executed, including inline script elements.
How do I change the indent size for formatted HTML?
Set Indent spaces to any whole number from 1 to 8 before running the tool. The default is 2 spaces per nesting level.
Can I beautify a partial HTML snippet?
Yes. You can paste a fragment such as a main element with children rather than a full document. Elements that fit within the line width may stay on one line.
Where is my input processed?
This operation processes its source in your browser. Copy and download are explicit actions; source input is not saved in an account or history.
What are the input limits?
Text operations generally accept up to 2,000,000 characters. Individual parsers, generators and formulas apply additional limits shown by their controls.
