HTML Minifier
Minify HTML by removing comments and extra whitespace.
HTML Minifier shrinks markup by collapsing whitespace, stripping comments, and optionally minifying embedded CSS/JS. Paste your HTML and download a smaller version for production. Runs fully in your browser.
Frequently Asked Questions
Does my text leave the browser?
No. This tool runs entirely in your browser. Nothing is uploaded to our servers.
Will minifying break my HTML?
Safe for most documents. Be careful with whitespace-sensitive content (e.g. <pre>) — review the output before shipping.
Does it minify CSS and JS inside the page?
Yes. Inline style and script blocks are minified when possible.
