HTML Minifier
WEBFree online HTML minifier that removes comments and whitespace to shrink pages, or beautifies them, right in your browser.
What it does
The Carbide HTML Minifier shrinks markup by dropping comments and collapsing the insignificant whitespace between tags, while preserving the contents of script, style, pre, and textarea blocks so nothing important is mangled. When you need readability instead, the same tool beautifies minified HTML back into cleanly indented, easy-to-scan markup. It is free, runs entirely in your browser, and is offline-friendly once loaded, so your code never leaves your device and is never uploaded to a server. Paste a fragment or a whole page, choose Minify for the smallest output or Beautify for clear nesting, then copy the result or download it as an .html file. It is ideal for trimming page weight before deploy, cleaning up exported templates, or inspecting compressed markup.

- No. The tool preserves the contents of script, style, pre, and textarea blocks verbatim, so your code and pre-formatted text stay intact.
