CSS is the web standard. It is the today and tomorrow of most of the graphics seen on the web. CSS3 and now, the latest CSS4 have even started to challenge JavaScript for day-to-day tasks.
But one cannot use CSS to its full potential unless he uses optimized code. And for that, one needs high quality tools for CSS Optimization.

These tools we are sharing today are free online tools that can parse, check, format, beautify, clean, validate, compress and optimize your CSS code for today’s web.

Online Tools for CSS Optimization

This is a brilliant resource for all web designers.


Devilous CSS tool

Probably my favorite tool for optimizing large size CSS files. Devilous smartens your CSS code by removing unnecessary codes and making them tidy, clean and slick. This is probably the best CSS code compressor available on the internet right now. It also supports CSS 3.0

CSS Comb

CSS Comb is a tool for ordering css code

The tool claims to be the greatest tool for sorting out your CSS codes. And you know what… it’s hard to argue with that. This tool really does the job better than anyone else. It can parse your code, sort your code alphabetically and through other standards, checks, formats and optimizes your CSS code. Supports up to CSS4 (Yes, there is a CSS4).

CSS Beautifier

CSS Beautifier formats your css code

Almost the same as CSS Comb but CSS Beautifier does not sorts your code as powerfully as CSS Comb does. Sometimes web templates and themes come with difficult to read CSS files. You just copy the code and paste in this CSS tool and voila!

CSS Lint

CSS Lint is one of the best CSS tools for code optimization

CSS Lint is one of the truest CSS tools for code optimization. It can do loads of stuff. Details would take too much time, so just go to site and click the arrow button on the right side of Lint button.


zBugs minifies your CSS code

This is one of the simplest CSS tools. It compresses and minifies your CSS code and converts the file into Gzip format. This tool also supports JavaScript.


Clean CSS

A fairly simple tool. Doesn’t support CSS3. Nice resource for beginners but not that awesome for the gurus.



This CSS tool does nearly everything you can ask for from a code optimizer.
