// and /* ... */ comments.---A JavaScript beautifier formats code with consistent indentation, line breaks, and spacing so it’s easier to read and maintain. A JavaScript minifier removes unnecessary whitespace and optionally comments to reduce file size and improve load times. Both are useful for debugging, reviewing third-party scripts, or preparing production builds.
This tool runs entirely in your browser for privacy. Beautify JavaScript when you need readability, and minify it when you want smaller payloads for faster website performance.
Beautifying only changes whitespace and formatting, so code behavior typically stays the same.
Minifying removes whitespace and optionally comments to reduce file size and improve load times.
Minification is usually safe, but rare edge cases exist (especially with tricky regex or string hacks). Test before deploying.
This is a lightweight minifier for quick use. It focuses on whitespace/comment reduction rather than advanced mangling.
Yes, it attempts to respect quoted strings and common comment styles, but extremely complex edge cases may need a full parser-based tool.
Semicolons can prevent automatic semicolon insertion edge cases. Keeping them is safer for mixed code styles.
No. Everything runs locally in your browser. Your code stays private.
Yes. This is a common use case for understanding or debugging included scripts.
Yes. Use bulk mode and separate blocks with ---.
Yes. Once loaded, it works offline since processing happens in the browser.
