Advanced Minify Settings Of W3 Total Cache Plugin

In the previous article, I have written about general settings of W3 total cache plugin which should be used by bloggers. There are many settings of this amazing plugin and you must know.

You should know advanced minify settings of W3 Total cache because most of the bloggers do it wrong and face problems with their website. As I have discussed earlier that if you do wrong minify settings of this plugin then it may break CSS of your website and even it can conflict with other plugins too.

If you want to use this plugin effectively then you should know about the best minify settings. In general, settings you have selected “auto” option for minifying the settings but do you know about its advanced settings?

Minify settings of W3 Total Cache :

For better performance, you should do the best minify settings of W3 Total Cache. Many bloggers may think that why am I focusing on these settings of this plugins? I must let you know that these settings are so crucial and you should know about them otherwise, you may fall into trouble. It’s better to know them so that you wouldn’t face any difficulty in future. I am going to show you the correct settings with some steps.

Step 1). First, you need to open “Minify” by going to “performance corner in the dashboard of your WordPress. You can find this option easily at which you have to click. After clicking to “Minify” a new tab will open in front of you where you will find many settings from which you need to choose the best.

Step 2). You can see that first setting is “General”  in which you can see some options. You should enable “Rewrite URL Structure”. It will help your users to get optimized results for their query. It’s a good practice to rewrite URL structure for embedded CSS and JS.

Another option is to “Disable minify for logged in users” by enabling which the logged in users will not get any minified page. But it’s better to keep the nature of your website same for all users.

Last option in this phase is to get a notification whenever your website gets any minification error. No need to enable it so select “Disabled” from the list.

Step 3). Here you come at “HTML & XML” settings. These settings are very important and you must keep an eye upon these. For better minification of your CSS and JavaScript files, you should “enable” it. Check to inline minification for CSS and JS which will ignore extra codes from the CSS and JS of your website. You should check on “Don’t minify feeds” because there is no need to minify your feeds. Only last option should be unchecked.

It is recommended that if you face any problem with the appearance of your website or any CSS error then you should disable this setting. Uncheck inline CSS & JS minification. I would recommend you to keep this setting disabled to have less risk.

There is another section to choose minification for the comments you get on your website. When minification is done then all the codes are removed to decrease page size but you should keep the comments from Google AdSense which is already written default. You can use any additional comments which you don’t want to get minified.

Step 4). Now it’s time to enable the JavaScript minify settings. Here you should click on “Enable”. Under “Operations in areas” you must use “Minify” with Default(blocking). Enable both the remaining option.

Note :- You must test this setting at your website and if you notice any visual change then disable it.

Step 5). In CSS minify settings you should check all the three options except “Combine only”.  In “@import handling” you must choose “process” from none, bubble, and process.

Note :- CSS id responsible for the design of your website and if you see any change in the design of your website then you shouldn’t use these settings.

Step 6). The last section is of advanced minify settings of W3 Total Cache. In this section, you shouldn’t click on the first option. Check it if you get any error related to the working of “Auto” option of minify. You can use manual option to remove such errors.


  • Filename length = 150
  • Update external files every = 21600
  • Garbage collection interval = 86400
  • Never minify the following = You can add particular pages you don’t want to get minified.
  • Never minify the following JS files = Here too you can add files which you want to get ignored.
  • Never minify the following CSS files = You have the option to add CSS files too.
  • Reject user agents = Leave it blank.
  • Include external files/libaries = Keep it default.


After doing setting for each section you should save settings. Keep in your mind that you may try these settings to reduce the page size of your website but most of the settings may harm the appearance of your website so it’s better to test them before permanent settings.

You can use CloudFlare with W3 Total cache plugin which can give better response in which you don’t need to do these settings.

Have you done minify settings of W3 Total cache properly?

Now have you become aware of the best minify settings of this amazing W3 Total cache? Are you ready to check this plugin with the minify settings?

It is dependent on the nature of your website and web hosting as how these settings would work? You have to do these settings with care and keep in your mind that after doing one setting you should check your website. If you see any visual change then it’s good to disable that setting.

Most of the settings are related to CSS and JavaScript so it’s better to check the design of your website every time to check minification for them.

    All the same, thanks for sharing, hope it would be beneficial to wordpress users.

    1. Hi Larry,

Website speed mattes a lot and using any caching plugin will help you in that. W3TC is one of the best caching plugin in WordPress directory and its necessary to know about its settings properly so that you can get more output from this plugin.
      Thanks for stopping by.
      Have a great day.:)

  3. Hi Ravi,
    This is going to be very helpful to bloggers who want to fine tune the decrease of their website load times. I am glad you mentioned that sometimes the minify settings can cause some loading and other css type issues with the blog. I think that it also depends on the theme that a blogger is using and plugins that they have. And I agree that it is a good idea to test things out before making the settings permanent. Sound advise! And I really like your tutorials!


    1. Hi Harish,

      This plugin is wonderful in its use but sometime it conflict with other plugins so its better to test it better activation. It may effect the CSS and JS of your website so you need to keep an eye at the design of your website while changing any setting. If you find any expected change in your website then you should disable that particular setting. In most of cases you need to look the design of your website because it is noted that W3TC settings may effect some CSS and JS files by reducing unnecessary codes from them.
      Thanks for sharing your thoughts with us.
      Enjoy your weekend.:)

  4. Hello Ravi,

    It is a nice tutorial and frankly speaking I really don’t know about that. But I do have a question will that be a problem if I use the above procedure with CDN ?

    Have a nice day !!

    1. Hi Rohit,

      You know there are many settings of W3 Total Cache plugin. You can use CDN with it in which most of settings would be same but still there are some changes you have to do. While using CDN you have to do minify settings according to that only. And other settings should be done with that only. Though it is experienced that W3TC with free cloudflare is also good in its response.
      Thanks for taking time to visit.
      Have a nice weekend.:)

  5. Hi Ravi,

    The minify settings are definitely the most important aspect of a caching plugin. It can improve a site’s load times drastically but even cause havoc instantly, if minify is not set right. So, its good that you took up this topic and explained it in detail.

    I’ve personally experienced many problems on Aha!NOW due to incorrect minify settings and learned the right way through trial and error.

    I’ve enabled the minify error notification so that I get to know if there’s any problem in minification. Under HTML & XML settings, I also have checked the line break removal option and everything runs smooth.

    In the JS minify settings, I’ve the embed type as non-blocking using “async” and under JS file management, I’ve specified the JS files that are shown as render-blocking by Google PageSpeed.

    Under the CSS settings, I had none @import handling, but now made it process after your suggestion. Again, under CSS file management, I’ve mentioned the CSS render-blocking files.

    I increased the garbage collection interval as per your suggestion. Sometimes, you do have certain pages or files that you do not want to minify, like the registration page or JS files of nrelate plugin or others.

    Overall, I agree with you that the user needs to go with the personal experiences and observations of the site and adopt what suits the site after experimentation. It’s also good to take the feedback of the site visitors because somethings that work at your end might not work at other places.

    If anything goes wrong, the minify option can be disabled, and the minify cache can also be manually emptied too. I do have CloudFlare, but I use the minify options of W3TC.

    There’s always scope for learning in blogging and site management and I thank you for bringing some new facts to light.

    1. Hi Vinay,

      No doubt that this plugin is great in its work but only if you use right settings. Most of bloggers do wrong minify settings due to which they get into trouble. They should know about perfect settings of this plugin so that it would be great for them to have better speed of their website.

      As I have mentioned above that its the matter of choice as if you want to enable error notification or not. Many bloggers don’t like to get notification again and again but somehow it helps to check the status of this plugin.

      While in JS settings there is not any proper settings because the settings get changed with the nature of Web Hosting. If you have VPS hosting then you have to use different settings which you use with shared Web Hosting.

      Minify settings are crucial and bloggers should know about them so that they don’t face any problem with their website speed.
      Thanks for dropping your informative input.

      Have an awesome weekend.:)

      Thanks for comment.
      Enjoy your weekend.:)

  10. Hi Ravi,

    I don’t use W3, but I like your suggestions about testing performance after each settings modification.

    I’ve found that with any plugin, it you set a bunch of things (or re-set), and then find incompatibilities with your theme or other plugins, it’s almost impossible to figure out. Then you tend to simply get rid of the plugin because it is “incompatible.”

    In fact, it may not be incompatible at all, but some of your settings may result in adverse performance with other plugins. So, you need to drill deeper. Your advice to test one setting at a time is excellent. Thanks for that.

    1. Hi Donna,

      In the case of W3 total cache you must check your website after doing each and every website because it may harm your website design. Many bloggers have experienced that with the use of this plugin they have many problem with their other plugins. This is all because they don’t use the correct settings.

    That’s why I appreciate these posts so much, you’re the man.

      Advanced minify settings are dependent on the type of web hosting you have. There are many changes in these settings for VPS hosting. And the most important thing is that you need to check them at your blog before allowing this plugin. Many hosting providers don’t prefer this plugin because it may create problem with their own super cache. But still you should know these minify settings.

    I am sure this post will help all those to fully optimize W3Total in first go without having any problem.

    Thanks for sharing this very useful and easy to understand post.
