HTML Beautifier & Formatter
Format and beautify HTML code with proper indentation, or minify it to reduce file size. Everything runs in your browser — your code stays private.
What Is HTML Beautification?
HTML beautification (or formatting) reorganizes HTML code with proper indentation, line breaks, and whitespace to make it human-readable. Minified or compressed HTML often comes as a single line — the beautifier restructures it into a clean, hierarchical format that's easy to read and debug.
This tool properly handles nested tags, void elements (like <br>, <img>, <input>), inline elements, comments, doctypes, and script/style blocks. The result is production-ready code that's both readable and properly structured.
When to Beautify vs. Minify
Beautify HTML when you need to read, edit, or debug code. If you receive minified HTML from a build tool or third-party source, the beautifier reformats it with proper indentation and line breaks. This is essential for code review, debugging, and maintenance.
Minify HTML before deploying to production. Smaller HTML files mean faster page loads and lower bandwidth costs. Combined with gzip compression on the server, minified HTML reduces transfer size significantly. Modern build tools usually handle this automatically, but this tool is useful for quick optimizations or testing.
Features
- Proper indentation with configurable spacing (2 spaces, 4 spaces, or tabs)
- Handles void elements:
br, hr, img, input, meta, link, etc. - Preserves inline elements option: keeps
span, a, strong, emon single lines - Respects
pre, code, script, styleblock content - Preserves HTML comments and doctype declarations
- Minification removes unnecessary whitespace while preserving functionality
- Character count and tag count statistics
- 100% client-side — your HTML never leaves your browser
How Much Can HTML Minification Save?
HTML minification typically reduces file size by 10-20% for well-written markup. Heavily indented or commented files can see savings of 30% or more. Combined with gzip compression on the server, total transfer size reductions of 60-80% are common. For large HTML documents, this translates to faster page loads and improved Core Web Vitals scores.
