HTML Minifier
Collapse HTML whitespace & comments.
Runs entirely in your browser — nothing you enter is uploaded, logged, or tracked.
Paste HTML to remove comments and squeeze out whitespace between tags for a smaller download — while the contents of pre, textarea, script and style are kept exactly as written, so layout and code are never broken.
Frequently asked questions
Will it break my pre or script blocks?
No. The contents of pre, textarea, script and style are preserved verbatim; only the markup around them is collapsed.
Does it remove comments?
Yes, HTML comments are removed (conditional comments are kept), and runs of whitespace in text are collapsed to a single space.
Is anything uploaded?
No — it runs entirely in your browser.
