Frequently Asked Questions
Everything you need to know about the Minifier.
How does the minifier work?
Paste your code and choose the language; it removes comments and unnecessary whitespace to produce a smaller, minified version, and shows how much you saved.
Is it free?
Completely free, no sign-up, downloads, or limits.
Which languages does it support?
HTML, CSS, and JavaScript, with a selector and an auto-detect option.
Will minifying break my code?
No. It uses proper minifiers that understand the language, so strings, template literals, and comments inside strings are preserved. Valid code stays valid.
What is minification?
Removing characters that aren't needed to run the code — whitespace, line breaks, and comments — to reduce file size and speed up loading, without changing behaviour.
How much can I save?
It varies by code, but the tool shows the exact bytes and percentage saved for your input.
Are important comments kept?
Licence-style comments (like /*! ... */) are preserved where the language's minifier supports it.
What if my code has an error?
You'll get a clear message and your input is left intact, rather than getting broken minified output.
Is my code sent anywhere?
No. Everything runs locally in your browser, so your source never leaves your device.
Does it work on mobile?
Yes, fully responsive; the input, output, and options fit the screen without overflow.
