8 CSS Compression Tools to Decrease Load Time

We all find ourselves searching for ways to decrease load time whether by enhancing our servers, the network, or performing code optimizations. One thing we all tend to do in different ways is the way we write out our CSS code. Some of us like to keep things shorthand, some of us like to separate each element, others do not like to lay out their code in a top to bottom fashion. Whichever way floats your boat, we all have one thing in common, seeking optimization. With that said, we dive right into CSS compression tools that help you optimize your code and additionally help you learn new optimization techniques to apply yourself.

CSS compression tools have an ultimate goal: to compress your CSS code as much as possible by eliminating and merging code to help eliminate download time. With that said, many compression tools use different techniques such as eliminating whitespace, merging properties and elements, and the likes. Therefore, when using these compression tools, make sure you do not quite overwrite your code with the compressed code for readabilities sake.

CSS Drive

CSS Drive

CSS Drive is a great utility to help increase load time and cut back on bandwidth usage. It uses compression modes to determine how far it should go on compression while providing you great control on how to handle comments within your code, which many CSS compression tools just strip out altogether.

CSS Compressor

CSS Compressor

CSS Compressor has to be second on my list for compression tools. Like CSS Drive, it provides different compression modes for you to choose from and it additionally provides some great compression options giving you great control on what it should tweak or touch exactly, and what it should not.

CSS Optimizer

CSS Optimizer

CSS Optimizer is a great lightweight CSS compression and optimization tool. You can easily upload your CSS file, or provide it by pasting the URL to it, and just hit optimize and it will do the rest. While it is lightweight, it is a great tool to jump on when you need some quick optimization performed.

Seven Forty

Seven Forty

Seven Forty is a great online compression tool based on the Java YUI Compressor. It has little to no setting customizations other than a line break option, but that should not mean that you should not use it, as its compression techniques are really extensive and definitely something you should put on your list to use.

Clean CSS

Clean CSS

Clean CSS is a great CSS compressor giving you complete control over what it does, and how. It contains a plethora of delicious customization options including a discard option which discards elements that are outside certain CSS versions. Additionally, if all the options it provides do not satisfy your own compression and optimization needs, you can create a custom code layout or template for it to base its compression and optimization techniques on to assure you are getting exactly what you want. Clean CSS is definitely a tool you do not want to disregard without at least giving it a try.



Pingates is another great CSS compression tool designed for long style sheets with countless lines of code that could use some compression and optimization. It has a nice set of options on how to handle rules, properties, and compression methods to give you some control on its methods.

Minify CSS

Minify CSS

Minify CSS is similar to that of Clean CSS with the template idea and set of options. It is another CSS compressor tool to give a whirl that might hit your favorites list.

Shy Gypsy

Shy Gypsy

While having an interesting name, it is a very lightweight simple option-less service with a simple CSS input and output box, along with a compress button. While being lightweight, it is a good tool to tinker with when you need something compressed quickly.
