HTML Minification
HTML contains significant whitespace for readability—indentation, line breaks, and spacing between tags. While browsers ignore most of this whitespace, it still transfers over the network. Minification removes it without affecting how pages render.
What Gets Minified
- Whitespace: Reduces multiple spaces to one, removes unnecessary line breaks
- Comments: Strips HTML comments (except conditionals)
- Optional tags: Removes closing tags that HTML5 allows to be omitted
- Attribute quotes: Removes quotes from attributes when safe
- Boolean attributes: Simplifies checked="checked" to checked
Embedded Content
HTML files often contain inline CSS and JavaScript. Our minifier can optionally process these embedded blocks, providing comprehensive minification in a single pass.
Safe Defaults
Aggressive minification can occasionally cause issues. We use safe defaults that preserve whitespace in pre tags, maintain conditional comments for IE, and keep significant whitespace in inline elements.
