Format and beautify or minify HTML markup instantly in your browser.
Beautify or minify HTML markup instantly in your browser. Format messy HTML into clean, properly indented code with configurable indent size, line wrapping, and newline preservation — or minify it for production by stripping comments and collapsing whitespace (pre, textarea, script, and style blocks are safely preserved). See original vs result size with percentage saved at a glance. 100% client-side: your markup never leaves your device.
The HTML Formatter & Minifier lets you instantly clean up messy markup or reduce file sizes for production directly in your browser. With configurable indentation, safe preservation of pre, textarea, script, and style blocks, and instant size reduction metrics, it streamlines everyday markup management without requiring software installations. Because processing runs entirely client-side, your code never leaves your device.
Good to know: Very large HTML files or automated pipeline workflows may benefit from dedicated command-line build tools rather than a browser-based utility.
