Does this minifier send my code anywhere?

No. All minification and beautification happens entirely in your browser. Your code never leaves your device.

How accurate is the minification?

It handles standard whitespace, comments, and formatting well. For advanced JS minification (variable shortening, dead code removal), consider tools like Terser or UglifyJS.

Can I beautify minified code too?

Yes, the Beautify button reformats compact code into a human-readable, indented structure.

Does it support TypeScript or SCSS?

The HTML tab works for any markup. CSS handles standard CSS. JS will work for TypeScript syntax in most cases since it focuses on whitespace and comments.

Is there a file size limit?

There's no hard limit, but very large files (several MB) may cause your browser to slow down since processing is local.

How do I minify CSS without Node.js?

Simply paste your CSS into this tool and click Minify, no Node.js, npm, or command line needed. It runs entirely in your browser.

What's the difference between minification and compression?

Minification removes whitespace and comments from code. Compression (like gzip) encodes the entire file into a smaller binary format. They're complementary, minify first, then compress on your server.

Can I minify multiple files at once?

Currently the tool handles one file at a time. Paste or type your code, minify, copy, and repeat for each file.

What Is Code Minification?

Minification removes unnecessary characters, whitespace, comments, and line breaks, from source code without changing functionality. The result is a smaller file that loads faster for your users.
