Many tools are available are available out there that can help you ameliorat your web pages’ loading speed, so here is a list of 7 Ways of Improving Your Page Load Time Using CSS and JavaScript. Check them out.

1. Site Load Test

Site Load Test

This one operates like a validator, and provides you more information about each error you encounter. Although it has got some errors, but still it will prove to be helpful for you in getting rid of tiny little errors you didn’t even think about. It also aids you in finding errors concerning uploaded files, websites’ size and total things to load, not only CSS and JavaScript faults you have made when coding. But keep in mind that this is not an app that will remove the errors all by itself but you are required to do it by yourself.

2. Packer

Packer will prove to be really helpful for all the people out there who wish to use JavaScript code in their webpage. Packer is not going to create the code for you, but it will compress it. This is a really quick tool. All you have to do is to copy your original code into the top field, followed by a click on “Pack”. And you will be provided with the same code but in a different state. Theis new compressed code will not cause any errors and will ameliorate the loading time.

3. SquishIt

SquishIt is a GitHub trademark. SquishIt will also help you a lot. If you have both CSS and JavaScript in your website then this tool will definitely make your life a little easier as it “bundles” both of them into a single file, reducing the number of files that need to be loaded. This tool has quite a poor interface so some people might find it a bit difficult to use at first, but once you get used to it, you will see how useful it can be.

SquishIt has a Google Group and the discussion forum that can help you even more. You can obviously get advice and opinions from there.

4. Minify


Minify is a PHP5 app that aids you with your CSS and JavaScript. It combines several CSS and JavaScript files and this thing removes white space and comments and transfers them with gzip encoding and optimal client-side cache headers.

If you have 5 JavaScript files, then they will be bundled into one. It is an extremely handy app that eliminates HTTP requests and reduces CSS/JavaScript bandwidth by 70%.

This app is incorporated in other projects too. You can use its plugin if you have WordPress: WP Minify and W3 Total Cache.

5. JSMin

JSMin removes the white space and comments from a JavaScript page just like Minify does. The official website of Minify states that it helps decrease the file size by half. JavaScript Minifier will not change anything else in your code, and will not cause any errors, so that the script will work nicely.

6. Google Closure Compiler

This tool is by Google that simply cleans your code to provide you a faster loading speed. It will efficiently correct and remove a great number of common coding errors in JavaScript.

This tool boasts a massive JavaScript library, which has been tested on many browsers and computers, a style checker and fixer and a JS optimizer. This tool is quite powerful and it works really amazingly, compiling up each of your JavaScript pages till there is nothing left to done.

7. YUI Compressor

YUI Compressor

As the name suggests, this tool compresses your files and it does it very quickly too. This tool works both with CSS and JavaScript and claims itself to be better than its rivals like Packer or JSMin. What this app does is that it simply preserves the qualities of the code and to only modifies the things that are not working perfectly.
