JavaScript Minifier FAQ
What does a JavaScript minifier do?
A JavaScript minifier reduces file size by removing comments, whitespace, and formatting that browsers do not need to execute the code.
Can minification break JavaScript?
Most simple minification is safe, but aggressive transformations can break code that relies on specific variable names or string formatting. Always test production output.
Should I use this instead of a build tool?
For production apps, use a bundler like Vite, Webpack, or Next.js. This tool is useful for quick scripts, snippets, and manual optimization.
