No. Our minifier only removes non-functional elements like whitespace and comments. For JavaScript, it performs safe variable renaming that preserves logical flow. Always test minified code before production use.

Typically 20-80% depending on code structure. JavaScript with many comments and long variable names sees 40-60% reduction. CSS with extensive formatting sees 30-50% reduction. JSON is usually 10-30% smaller.

Yes, minifying JSON simply removes whitespace and newlines. The data structure remains identical and valid. This is commonly done for API responses to reduce transmission size.

Never. All processing happens in your browser using JavaScript. Your code is never sent to our servers, logged, or stored. Refreshing the page clears all input.

Minification reduces file size by removing whitespace and shortening names. Obfuscation intentionally makes code hard to read for security. Our tool minifies only—it doesn't obfuscate or protect code from reverse engineering.

Currently, files are processed one at a time. For bulk minification in projects, consider build tools like Webpack, Vite, or Rollup which handle multiple files and generate source maps.

Minified code is harder to debug due to single-letter variable names and no line breaks. For production debugging, generate source maps alongside minified code to map errors back to original source.

No. Only minify for production builds. Development should use readable, formatted code with full comments. Minification is an optimization step before deployment.
