JS Beautifier / Minifier

Format or minify JavaScript

This tool does two things. Beautify turns compact or messy code back into something readable with neat indentation. Minify does the opposite: it removes spaces, comments and unnecessary characters so your file is as small as possible — handy for production.

How it works

1. Paste your JavaScript into the input field (or click “Example”).
2. Choose “Beautify” or “Minify”.
3. Copy the result with one click.

Good to know

• If there's a syntax error while minifying, you'll get a message.
• Your input is kept when you reopen the page.
