Frequently Asked Questions
What is CSS Minification?
CSS Minification is the process of removing unnecessary characters from source code without changing its functionality. This includes removing whitespace, newlines, and comments.
What is CSS Beautify?
If you have minified code and want to read or edit it, the Beautify button adds back indentation and newlines to make it human-readable.
Why should I minify my CSS?
Minified files are smaller in size, which leads to faster download times, reduced bandwidth usage, and better SEO rankings due to improved page speed.
Is minification safe?
Yes, minification does not change the logic of your CSS. It only changes how the code is written, which browsers can interpret perfectly.
Who is this tool for?
Web developers, site owners, and SEO specialists use this tool to optimize their website performance and clean up their production code.
Are comments preserved?
No, standard CSS comments (`/* ... */`) are removed during minification to save maximum space. If you need to keep specific license comments, you should add them back manually.
When to use minified CSS?
Always use minified CSS in your production environment. You should keep the original (beautified) version for development and only minify before deployment.
Can I minify multiple files?
Currently, you can paste the contents of multiple files into the input area to combine and minify them all at once.
Where to use the output?
Save the output into a `.min.css` file and link it in your HTML `
