About This Tool

The tool accepts an HTML string and a set of formatting options. The core capability is to parse the HTML into a structured model and reserialize it using the chosen rules, producing formatted output that is easier to read and maintain.
Key features include indentation control (spaces or tabs, size 2 or 4), optional wrapping of attributes, a maximum line length, and a choice of quote style for attributes. It also preserves content within pre, code, or script blocks and normalizes the rest of the markup.
Intended users include developers, CMS teams, QA, and content authors who must deliver consistent HTML across environments. The tool helps reduce diffs in code reviews, prevents inconsistent spacing, and supports CI workflows via integration as a string formatter. Unique value comes from combining parsing accuracy with flexible, non-destructive formatting rules and a focus on producing valid, standards-compliant markup.
Common use cases include template formatting, email HTML formatting, and linting in pull requests. Edge cases such as heavily malformed input yield best-effort output with diagnostics, while safe transformations aim to preserve semantics.

Frequently Asked Questions

Find Quick Answers

What input formats are supported?
The formatter accepts a raw HTML string or fragment as input. It does not fetch external resources or execute scripts. It preserves script/style content, but formats surrounding markup. It targets standard HTML5 markup and can handle common templates, emails, and CMS partials.
Can I minify output?
Yes. Enable minify mode to collapse whitespace between elements, remove unnecessary line breaks, and reduce attribute spacing. Minified output remains syntactically valid and suitable for production HTML, email markup, and delivery contexts.
How are attributes wrapped?
If max_line_length limits are configured, attributes may wrap onto new lines with consistent indentation. Short attributes stay on one line when feasible. The tool aims to keep readability while respecting the line-length target.
Is output guaranteed to be valid HTML?
Output is formatted to be valid HTML if the input is well-formed. The tool does not perform full validation or semantic checks, and it may not correct deeply malformed markup; it preserves content and attempts safe restructuring.
