Frequently Asked Questions
Does HTML minification break any functionality?
When done correctly, no. Whitespace between block elements is not significant, and comments are decorative. Whitespace inside <pre> tags and inline elements is preserved by default to avoid visual changes.
Should I minify HTML in production?
Yes, especially for server-rendered pages. Every byte saved reduces time-to-first-byte. Combined with gzip compression, minified HTML can be 60–80% smaller than unminified.
Are HTML comments removed during minification?
By default, yes — HTML comments are removed as they have no effect on rendering. The exception is conditional comments (<!--[if IE]>) which are sometimes preserved.
