Frequently Asked Questions
What does HTML minification do?▼
HTML minification removes unnecessary characters from HTML without changing functionality. This includes whitespace between tags, HTML comments, redundant attributes, and optional closing tags. The result is a smaller file that loads faster.
Is minified HTML still valid?▼
Yes. Properly minified HTML is fully valid and renders identically to the original. The browser processes both versions the same way — it just downloads fewer bytes.
How much can HTML be compressed?▼
Typical HTML files can be reduced by 10-30% through minification. Files with lots of comments and whitespace see larger reductions. The tool shows exact compression statistics.
Is my HTML sent to a server?▼
No. All minification happens entirely in your browser using JavaScript. Your HTML never leaves your machine.
