Frequently asked questions
- What does JS minification remove?
- It strips comments (single-line and multi-line), collapses whitespace, and removes unnecessary characters. String literals and template literals are preserved exactly as written.
- Does the beautifier produce production-quality formatting?
- The beautifier adds consistent indentation and line breaks for readability. For complex formatting needs like specific brace styles or semicolon preferences, a dedicated IDE formatter may be more suitable.
- Is my code sent to a server?
- No. Both minification and beautification run entirely in your browser using plain JavaScript. Your code never leaves your device.
