Importance of Image Compression : A Great Performance Factor

In this article you are going to get info on how much important image compression can be in obtaining a good level of performance for your website. You will also get info on various image resize plugins that you can use as well to compress images.

If you are using images and not compressing these images on your post then this might be the prime reason for your website’s reduced performance.

So as the title suggests image compression is very important for your website performance. If you are not doing image compression then you are bringing extra load to your website itself.

Now let me get you to the point straight :

The compressed images in your website will load faster than uncompressed images. So for better performance always compress the images before uploading to your website.

Now let’s see how images affect your website performance or load time.

How images affect your website’s performance :

As we know images are very important for making your content engaging. Without Images our blogs will look not so decorative and appealing as it looks with images.

But using images without properly optimizing it can cost you performance. The thing is that an image can take more space than the whole texts sometimes. So images can make your website heavier to load due to it’s size.

Some reasons how images can reduce website performance :

  • If you have not compressed images before uploading then it will add extra heaviness into the website. The heavier the website the slower it becomes to load.

  • The larger images take more number of inodes on your servers. So again that is how you will lose unnecessary inodes if you use unnecessarily larger images. This can cost you a lot in future if you are given limited inodes by your hosting.

  • Even if you have unlimited Inode limits you still should use smaller or compressed images because there is going to be a lesser load on the visitors browser to fetch it. right !!

Furthermore according to imagify images can account for 50% of your loading time.

In short Larger sized or uncompressed images will become heavier for browsers to fetch and show it on visitors’ screen. So always do image compression before using the image on your website.

So if you really want to see rise in performance then use lesser images or compressed images.

Importance of Image Compression :

Now seeing the reasons how images can take most of your content space it is always better to compress the images.

No matter smaller or bigger you should do image compression of every image that you are going to use over the internet.

Use compressed images everywhere :

Not only on your website but also on various social media posts you should use compressed images. I am talking about using compressed images on Instagram and Pinterest as well.

Because if you are using compressed images over the internet you are doing a great job. It makes it easier for the browser to fetch the images and present it to the visitors.

So it’s a thumbs up from the whole internet to you if you are using compressed images everywhere. It reduces burdens off the servers and browsers eventually.

So who knows maybe if your images are compressed over Instagram and Pinterest then your account might perform better than others. 🙂

Now let’s see how you can do image compression.

Ways to do image optimization or image compression :

So there are two ways you can do Image Optimization :

1) Image Optimization or compression before uploading to WordPress Website.

2) Image resize or Image compression or Image optimization after uploading to WordPress with a Plugin.

Now there is a question : which method is better !!

Answer :

The first method is better in general. Because you don’t have to invest in any Plugin and you are giving lesser workload to WordPress.

How to do Image Compression before Uploading to WordPress ?

Answer :
