Frequently Asked Questions
Why should I minify code?
Minification reduces file size, which speeds up page load times and reduces bandwidth usage. Smaller files parse faster and start executing sooner.
Does minifying change how my code works?
For JavaScript, no — removing whitespace and comments does not affect runtime behavior. For CSS and HTML, collapsing whitespace can occasionally affect visual layout (e.g. removing the space between adjacent inline elements). Review the output before deploying to production.
Is it safe to minify production code here?
Yes, all processing happens in your browser using JavaScript. No code is sent to a server.
What is the difference between minification and obfuscation?
Minification reduces file size by removing unnecessary characters. Obfuscation (like mangling variable names) makes code harder to reverse-engineer. Both can be applied together.
