HTML Minifier
Paste HTML and get a lighter version in real time. Comments are removed (IE conditional comments survive), runs of whitespace collapse to a single space, and whitespace between block-level tags is dropped entirely — while inline text spacing is preserved so words never fuse together.
This is a deliberately conservative minifier: it does not rename classes, remove quotes or restructure anything. That makes it safe for email templates and legacy markup, and the live size readout shows exactly how many bytes you saved.
Frequently asked questions
Can minification break my HTML?
This tool takes the safe route: whitespace inside pre, textarea, script and style is untouched, whitespace-only gaps between inline elements become a single space, and only gaps between block-level tags are removed. Comments are dropped except IE conditional comments.
Why is the saved percentage lower than other minifiers?
Because it is conservative by design — it never merges text with tags or removes quotes. What it does remove (comments, indentation, inter-block whitespace) is always render-safe.
Is anything uploaded?
No. Everything runs locally in your browser; the page and its markup never leave your device.
