Meet CSS Uglify and Prettify, a simple online tool that does exactly what it says; uglifies and prettifies CSS quickly and easily. Minify your CSS in a hassle-free way, or prettyprint it into human-readable format.

Uglify (or minify), in computer science is the process of removing all unnecessary characters from source code without changing its functionality. These unnecessary characters usually include white space characters, new line characters, comments, and sometimes block delimiters, which are used to add readability to the code but are not required for it to execute. Uglified source code is especially useful for interpreted languages deployed and transmitted on the internet (such as Cascading Style Sheets), because it reduces the amount of data that needs to be transferred.

An uglified source code may be reversed using a prettify (or prettyprint) process, which applies various stylistic formatting conventions to it. These formatting conventions usually adjust positioning, spacing, and similar modifications intended to make the content easier for people to view, read, and understand.

Easy to use

Begin with the "type (or paste) here..." area to enter your data, then hit the "uglify" or "prettify" buttons respectively. After a blink of any eye, the results will be shown below these buttons. That's all!
