About the JavaScript Beautifier

Turn minified or messy JavaScript into neatly indented code.

Paste your code into the input box, or click Load Sample to load an example.
Choose a Style Preset: Modern (4 spaces), Compact (2 spaces) or Legacy (Allman braces).
Under Advanced, tick Break Chained Methods or Unescape Strings if needed.
Press Beautify Script.
Use Copy (or Download where shown) to keep the result. Clear empties the box.

Beautifying does not change what the code does, only how it is laid out.
Your code is not saved by this page, but avoid pasting passwords, API keys or private data into any online tool.

Can it restore the original variable names of minified code?

No. Minifiers replace names permanently. Only the layout can be restored.
