HTML Minifier
Minify and prettify HTML online to optimize source code and improve readability.
About This Tool
This free online HTML minifier helps you quickly compress markup by reducing whitespace and optional comments. It is useful when you need smaller snippets for embeds, templates, and production output where reducing payload size improves delivery performance. You can also switch to prettify mode to turn compressed HTML back into readable structure for debugging and review.
The tool runs entirely in your browser so your markup is not uploaded or stored on IO Tools servers. With simple and advanced UI modes, both beginners and experienced developers can clean HTML fast without local setup.
