JavaScript beautification makes compressed source easier to read and inspect

Beautification adds indentation and line breaks to JavaScript source so functions, blocks and expressions are easier to follow during debugging or manual review.

A beautified script is not automatically safe, correct or understandable. Obfuscated logic, dynamic code and application behavior still require real code analysis.

Useful beautification tasks

  • Inspect a compact script during debugging.
  • Create a readable working copy of source you are authorized to analyze.
  • Review block structure before making manual edits.

What beautification cannot do

  • It does not reverse all forms of obfuscation.
  • It does not establish whether code is safe to execute.
  • It does not replace linting, testing or source-level documentation.

Before relying on the result

Keep the source until you have checked the generated output. The source and destination formats can represent structure, layout and metadata differently, so important documents should be reviewed in the application or device where the result will actually be used.
