Frequently Asked Questions
Find answers to common questions about our CSS & JavaScript Compressor.
Is this CSS & JavaScript compressor free to use?
Yes. This tool is free to use without an account.
Will my code be stored on the server?
No. Files and code are processed locally in your browser by this tool.
What is the benefit of minifying CSS and JavaScript?
Minification can reduce transfer size by removing comments and unnecessary whitespace.
Can I upload .css and .js files directly?
Yes. Use the Load File button above either editor.
Does it support modern CSS and JavaScript (ES6+)?
The CSS compressor supports common modern CSS syntax. The JavaScript compressor uses conservative whitespace and comment removal; it does not rename variables or perform full AST minification.
Will it break my code?
Complex JavaScript syntax can be sensitive to whitespace and comments. Review and test minified files before using them in production.
