About the JavaScript Whitespace Minifier

This lightweight JavaScript whitespace minifier protects quoted strings and template literals while trimming indentation and redundant blank lines. It deliberately keeps comments and tokens intact instead of attempting risky parser-free rewrites.

How to use the JavaScript Whitespace Minifier

  1. Paste a valid script.
  2. Create the conservative compact version.
  3. Run tests before using the downloaded file in production.

Practical tips

  • Use a parser-based project build tool when comments, identifiers and dead code must also be removed.
  • This conservative output keeps regular-expression literals and automatic semicolon insertion boundaries intact.
