HTML Formatter
Paste an HTML fragment and expand its tag structure into readable indentation without executing the markup.
How this tool works
The formatter separates adjacent tags, tracks opening and closing element depth, and treats standard void elements such as img, input and br as self-contained.
Example
A compact main element containing headings, paragraphs and list items becomes a nested, line-oriented representation.
Common questions
Is this a full HTML parser or beautifier?
No. It is a lightweight formatter for common markup and may not perfectly format malformed or unusual embedded content.
Does it execute scripts in the pasted HTML?
No. The input is treated as text for formatting.
