HTML Formatter
Make compact HTML easier to read with consistent indentation.
About HTML Formatter
Readable HTML helps when examining templates, copied snippets, and generated markup. This formatter separates tags and text onto lines and indents nested elements so a document’s structure is easier to scan.
Browsers intentionally repair many HTML errors, and this simple formatter is not a standards validator or a DOM-preserving minifier. Review the output for inline elements and whitespace-sensitive content such as preformatted text before using it in production.
How to use this tool
Paste HTML source and choose Format HTML. Review whitespace-sensitive sections and confirm the result in your own rendering or test environment.
Frequently asked questions
Does this validate HTML against the standard?
No. HTML is tolerant of malformed markup, and this formatter only adjusts line layout and indentation.
Can formatting change rendered text?
Whitespace between some inline elements or within preformatted content can affect rendering. Inspect those areas and test the formatted markup before publishing it.
Is my markup uploaded?
No. The formatter processes the text in your browser and does not send it to a formatting API.
