Minify HTML, CSS, JavaScript, and JSON online

Minifiers strips whitespace and comments from your code to reduce file size before shipping to production — with instant before/after size comparison.

Why use this tool

Four languages in one tool

HTML, CSS, JavaScript, and JSON minification without switching between separate tools.

Instant size savings

See exactly how many bytes — and what percentage — minifying saves.

Safe transformations

Only whitespace and comments are removed; your code's behavior stays identical.

Private by design

Minification happens entirely in your browser.

How it works

  1. 1Pick a language: HTML, CSS, JavaScript, or JSON.
  2. 2Paste your code into the input box.
  3. 3Copy the minified result or download it as a file.

Frequently asked questions

Good to know

  • Minifying removes whitespace and comments — it doesn't change what your code does.
  • For maximum JS/CSS compression (variable renaming, dead-code removal), use a build tool like esbuild or Terser.
  • Runs fully in your browser — nothing is uploaded.
