HTML Minifier
Strip whitespace and comments from HTML to reduce file size.
What gets removed
Redundant whitespace between tags, blank lines, and optionally HTML comments are all safe to remove without changing how a page renders, since browsers collapse most whitespace in rendered output anyway.
Minify at build time, not by hand
Minification is meant to be an automated build step run against your final output — never hand-edit a minified file directly, since any change will be lost on the next build.
Common Mistakes to Avoid
Stripping comments a template engine relies on
Solution:
Some server-side templating uses HTML comments as markers. Review your comments before enabling comment removal if your build relies on them.
Minifying content inside <pre> or <textarea>
Solution:
Whitespace inside these tags can be meaningful. Double-check formatted code samples or ASCII layouts after minifying.
Frequently Asked Questions
No — only whitespace and optionally comments are removed, both of which browsers already ignore when rendering.
No — minification happens entirely in your browser.
