Frequently Asked Questions

What does JavaScript beautifier do?

It takes minified or compressed JavaScript and reformats it with proper indentation, line breaks, and spacing for readability.

Will it change how my code runs?

No. Beautifying only affects whitespace and formatting. The code behavior remains identical.

Does it rename variables back?

No — if variable names were mangled during uglification, this tool cannot restore original names. It only reformats structure.

Is my code stored?

No. Everything runs in your browser. Nothing is sent to any server.
