About This Tool

The HTML Minifier compresses your HTML documents by stripping unnecessary whitespace, removing comments, collapsing boolean attributes, and eliminating optional closing tags. Paste your HTML and get an optimized version with a clear breakdown of the size reduction achieved.

While CSS and JavaScript minification get more attention, HTML minification provides meaningful savings - especially for content-heavy pages, email templates, and server-rendered applications that generate large HTML documents. Removing just whitespace and comments can reduce HTML size by 10-25%.

The tool applies safe optimizations that preserve the visual rendering and functionality of your document. It handles modern HTML5 features including custom elements, data attributes, SVG inline content, and template tags. Options let you control which optimizations to apply, keeping full control over the output.
