It is one of the most effective web development processes to have fast loading web page speed. Read further on to get detailed insights about what minification really is and how it works.

What is Minification in detail?

Minification can be defined as the process of reducing all unused code and characters from the original code of the page without letting the functionality be altered or sacrificed. It works in such a way that it eliminates a code file containing all redundant or unnecessary data that are unimportant for the file to be carried out.

Unnecessary code happens because of the use of characters like comments, block delimiters, line breaks, and white space characters. In order to make code lighter, you can concatenate those unused files and save memory.

Minification is carried out once coding has been completed, before final deployment. It is majorly about editing your code to make it quickly accessible for webpage visitors. As a result, minifying CSS & JavaScript allows your users to get fast access to the minified version of the webpage instead of rendering its full version.

If seeing a bigger picture, increases the response times and reduces the loading time. Whether you are having a blog, or high traffic website, minifying will be beneficial. Minification can be used with different languages like; HTML, CSS, and even JS.

How Does Minification Works?


Minification is a well-known development practice that works in a way that allows developers to rework the general code file and make reductions in the size of the file. Minify Resources helps in extending the script, style, and other components used by the web browser to power the website.

Minification makes code lighter to render the website, making your website assets and resources quicker to distribute to the requested users. But what the minification is exactly about is what you need to understand with this how-to guide.

The browser reads all the extra characters that the web page developer creates while writing code. As a result, the webpage becomes heavier and larger to load. The optimization developer Minify Resources or eliminates this extra code present in the form of whitespace, comments, and line breaks, that were previously action as redundant space in the file.

These excesses of code don’t require the computers to render the page. When a code goes from the Minify Resources process, it goes a long to reduce the file size by the given process:

  • A web programmer makes a JavaScript or CSS file of a web page which will be further formatted by the programmer or optimization developer to make it minified.
  • The optimization developer will use minification to convert the file into its light and short version. The minification process helps in making creating an augmented or compressed format of a web page. This compact code of the file is now difficult to understand. The popular ways to minify your file are to reduce every variable name, eliminate all the white space within a file, converting longer functions into short functions.
  • Minified version of the webpage used by the web server and used when a response is required by the user to render it. This minified page uses less bandwidth without sacrificing the original function of the files.

  • You don’t need to download unnecessary data: After removing the unwanted codes like; comments, line breaks, from the code file. Minification can help you reduce the file size by keeping important code from the general file and removing unnecessary code. Accordingly, this saves your users time by not allowing them to download unnecessary data.

Doing concatenation can significantly reduce the number of files that need to be downloaded, thereby, greatly increasing the speed.

Why don’t developers write minified code?

JavaScript code written by programmers uses whitespace, formatting, and comments to let other programmers understand and debug the code. While minification results in compressed code to achieve higher web performance, it is also harder to understand minified code.

What are the disadvantages of minification?

Minification makes the scripts straightforward and breaks complicated code because of site variables like themes, plugins, and servers. Moreover, it must be done in conjunction with other performance optimization tricks and techniques. Minification doesn’t have significant gains and can also end up giving many errors that are hard to debug.
