Best Image Optimization Plugin WordPress 2020: Is your site slow due to heavy image file size? Don’t worry! I am sharing with you the 5 best image optimization plugin WordPress 2020 to speed up your WordPress website.

Also, I am showing you the process of how to reduce image size online for your website, social media, etc.

Most people make the mistake of uploading their pictures to their website without compressing them. Especially beginners don’t give it much importance on this WordPress image optimization topic the first time and they make mistakes there.

As a result, the site is running slow and they lost their visitors, as well as increase the bounce rate of their website.

For example, if you have hosted an image website or writing blog posts on your website, there are lots of pictures you are used for your image website or blog posts. So that you have to know the process of image optimization to increase your website speed.

Similarly, you can reduce image size for any purpose like sending a fast email, quick upload your image in social media or an online photo gallery, etc.

Today I am helping those beginners who not to do again these mistakes. There are several ways to optimize images for your WordPress website. So, I am sharing the best image optimization plugin WordPress 2020 with you and all the ways and processes within this post.

Why is it important to optimize or reduce image size?

Previously, I have already told that if you hosted a website or you want to write blog posts for your website, lots of photos are needed and those images have to be optimized.

Because if you don’t optimize your images, you don’t rank in Google SEO. So the main reason to optimize your images is to take up lesser space, faster site and also for better ranking in the Google SEO.

If you are downloading HD images from free image sites like Pixabay, Pexels or Unsplash to use them or download the graphic design images for your blog posts, those images are high-resolution images and their sizes are in Megabyte (MB).

So, if you are using those images for your blog post and not optimized then your site will be slow down.

Similarly, those high-resolution images are also 4000 pixels wide and 3000 pixels height. By reducing the size of these high-resolution images as well as resizing of these images are also important.

You can resize and reduce image size directly from your WordPress. Let’s see how I do it?

Resize & reduce the image size in WordPress

— Reduce Image Size in WordPress

Choose your image which you want to resize from the media library. As you see on the above screenshot file size is 325KB and the dimension is 1920 w x 1200 h. Now I am going to change the dimension as well as reduce the file size of this image. Click on Edit image.

After that, this page will open in front of you. From here, you can change the dimension of your image from the left-hand side. Just enter your image width then it automatically chooses the height of your image. Then click on Scale. After that, Clik on Update.

As you can see on the above screenshot, it reduces the image file size from 325 KB to 54 KB as well as resize the dimension from 1920h x 1200w to 800h x 500w of this image.

From the beginning of this article, as I mention that speed matters for your website and your blog posts. In fact, studies have shown that over 53% of mobile users will leave the site if it takes more than 3 seconds to load.

If you have a responsive website then I recommend you to analyze your site speed with Google’s page speed insight tool. It analyzes the Mobile and Desktop version both and gives you a detailed report.

If you want to specifically check your site speed for mobile version then test it with Google’s “Test my site” tool. It indicates you how fast your site loads and try to load your site within the 3 seconds.

How to resize & reduce image size with the Online tool?

These online tools are very helpful to reduce and resize your images. These tools help you to save your webspace as well as make your website fast. Here I am covering all the process, let’s see…

1. TinyPNG

TinyPNG is a popular site for compressing your image file size both JPG and PNG files. It compresses your maximum image file size based on the resolution of your image. But the quality of the image remains the same as your original image shows.

But there are some Pros & Cons in the free plan.

By default, it is selected the “C” method, but you can change them within the method A to E & after that, select the image quality (%) as per your choice. Also if you want not to change the quality of your image then select the F or G method.

You can play with these methods and see what compresses well without losing the quality. But my recommendation is that select within the D or E method and select the image quality 50 – 80%.
