JS & CSS Unminifier

Frequently Asked Questions

What does a JS & CSS unminifier do?

Our free (no hidden costs) JS & CSS Unminify tool lets you uncompress, reformat, and reindent ugly JS & CSS code to make it readable. Copy and paste your code directly into the box above, or upload multiple JS or CSS files to see the unminifier in action. This tool is especially useful if you want to analyse a site’s JS or CSS code, but you only have access to the minified version.

Why would you unminify JS or CSS code?

Minified JS & CSS code is streamlined to the point of being unreadable. It’s easier for servers and search engines to load minified code, but almost impossible for people to read it. If you want to be able to easily read this code, you have to recover lines, spaces, and other elements that were deleted through minifying. Our free JS & CSS Unminify tool can do this automatically, within seconds.

How do you use this tool?

Using our free tool is super simple. Just copy paste your minified code into the box above, or drag-and-drop entire files in the outlined area. Confirm whether you want to unminify JavaScript or CSS code, then click the “Unminify” button. Within seconds, you’ll have access to the unminified version of your code.

Can I still optimize my code after unminifying it?

Absolutely. Once you’re done analysing or editing the code, use our free minifier tool to remove unnecessary spaces and lines. This will reduce all your JS & CSS files by up to 80% of their original size.
