HTML / CSS / JS Beautifier
Beautify or minify HTML, CSS, and JavaScript. Companion to the JSON formatter.
100% client-side — your data never leaves this device.
Beautify uses js-beautify. JS minify is conservative (not a production bundler minifier).
Format or compress code
Paste HTML, CSS, or JavaScript to pretty-print for readability or compress for size. Pair with our JSON formatter for full-stack snippet cleanup.
