About the JavaScript Beautifier

Paste minified, bundled or badly indented JavaScript and get it back with consistent indentation and line breaks, so you can read a production bundle or clean up a snippet before sharing it. It parses the code rather than guessing, and runs in your browser.

• Re-indents and re-breaks code from a real syntax tree
• Good for reading minified bundles and third-party scripts
• Nothing is uploaded

Frequently asked questions

Can it restore original variable names?

No. Names shortened by a minifier are gone unless you have a source map. Beautifying restores layout, not names.
