About HTML Formatter
The HTML Formatter indents tags and attributes for readability, or minifies markup for faster page loads. It is useful when auditing landing pages, email HTML, embed codes, or server-rendered templates that arrived as a single compressed line.
How to Use HTML Formatter
Paste your HTML document or fragment into the editor. Run Format HTML to apply consistent indentation to nested elements. Switch to Minify HTML when you need compact markup for templates or inline bundles. Copy the output into your IDE, CMS, or testing environment.
When to Use HTML Formatter
Web development: Inspect nested `<div>` structures, forms, and semantic landmarks quickly. Email marketing: Pretty-print table-based layouts before troubleshooting rendering issues. SEO & accessibility reviews: Scan heading order and alt attributes in a clear layout. Education: Teach students how elements nest without fighting unreadable source.
Why Use This HTML Formatter?
Well-structured HTML is easier to debug and safer to edit than minified source. This tool gives you both pretty and compact output without local CLI setup, which helps freelancers and teams who only need occasional formatting.
