CSS, JS & HTML Minifier / Beautifier
Compress your code to shrink file size and speed up page loads, or beautify minified/messy code back into a clean, readable format — all in your browser.
Why Minify or Beautify Code
Faster Page Loads
Minifying removes whitespace, comments, and extra characters, cutting file size so your pages load faster.
Smaller Bandwidth
Smaller CSS/JS/HTML files mean less data transferred, which helps on mobile connections and reduces hosting costs.
Readable for Debugging
Beautifying reformats compressed or messy code with proper indentation, making it easy to read and debug.
Runs In Your Browser
All processing happens locally in JavaScript. Your code is never uploaded to any server.

Frequently Asked
Questions
1. Is it safe to minify my code with this tool?
Yes. All minifying and beautifying happens entirely in your browser using JavaScript — nothing you paste or upload is sent to a server, so your source code stays private.
2. Will minifying break my CSS, JS, or HTML?
The minifier only strips comments, line breaks, and unnecessary whitespace — it doesn’t rename variables or change logic, so the resulting code behaves the same as the original. As with any minifier, it’s a good idea to test the output before deploying to production.
3. Can I beautify already-minified code?
Yes. Paste your minified/compressed CSS, JS, or HTML into the input box and click Beautify to reformat it with proper indentation and line breaks.
4. Is there a file size limit?
There’s no hard limit enforced by the tool, but since everything runs in your browser, extremely large files (several MB of code) may process more slowly depending on your device.
