Beautiful HTML Formatter

The Beautiful HTML Formatter converts input HTML into a clean, readable, and consistent markup version. It targets developers who maintain templates, content teams producing email or web content, and teams enforcing code style across projects. It handles typical HTML fragments and full documents, producing predictable outputs that facilitate review and collaboration.
Conceptually, the tool tokenizes the markup, reconstructs the tree, and serializes it with defined indentation and line breaks. It distinguishes between element nodes, text nodes, and comments, applying rules for multi-line attributes, quote styling, and self-closing tags. The result is stable across repeated runs for the same settings.
Unique value includes deterministic formatting, quick turnaround, and parameterized output that integrates into build pipelines. Use cases include standardizing HTML templates, processing CMS exports, and preparing markup for email campaigns where consistency matters. It supports HTML5 semantics and can be integrated into development workflows to enforce consistent markup across teams.
Core features include indentation control, optional minification, attribute wrapping, doctype preservation, comments handling, and script/style blocks handling. Outputs include the formatted HTML string and optional metadata such as input size, output size, and processing time.
