An Images are account for the vast majority of the downloaded bytes on a site page and furthermore frequently involve a lot of visual space. Accordingly, optimizing images can frequently yield a portion of the biggest byte saving and improvement for your site.

What is image optimization?
Image optimization is about minimizing the file size of your images without sacrificing quality so that your website load times remain low. Other than that, it can also improve your website SEO on search engine.
Png vs Jpg for Web
PNG format is a lossless compression file format, which is common use on the Website. JPG format is a lossy compressed file format, however it’s also good for website and smaller size than a BMP format. But if for smaller icon or graphic, png is better because it’s lossless. I personally also prefer png, because the quality look better on web, even I’ve reduce image size in kb.
Use Facebook to Reduce Image Size in kb
Facebook have their own way to optimize all image in facebook, every image from users sending to facebook, the size will be reduce in kb. Thus, we can use facebook to do image optimization.
Upload you image to Facebook or Messenger, open the image and “Download”, it easy. Now, let see our experiment on the below.
To do the experiment, we need one image from Facebook, and one original. I have already upload one image to Facebook messenger through my phone, the image was taken from my iPhone. On the below, you can see the comparison of the two image. The image on left is original image taken directly from my iPhone, and the image on right was downloaded from Facebook messenger.
As we can see, the original image size was 3.45 MB, which is very large. And messenger have reduce image size in 148kB(without using compression tools), which is 23x time smaller size than the original files.
If you using original image without any compression in your website, you may take longer time while loading the website. As a site speed for google is a ranking factor, fast site is good user experience and a satisfaction will leads to higher conversions.
53% of visits are abandoned if a mobile site takes longer than three seconds to load. That’s a big problem.” Google

Find the Actual Size of Place hold
Another way to optimize the images on your website, is to find the actual size for the image place hold. Actual size can prevent you use an over size image and reduce image size in kb, which will decrease your website load size.
To find the actual size, we can simply use the website inspect to find the image place hold, and check for the size. Here, i will demonstrate for image used in blog post.
To do this, simply open one of the blog post. After that, press “F12” on your keyboard to open inspect. Click on the selecting tools (the icon see screenshot).
Now, move your mouse to the content place and find the “inner-post-entry”. Because WordPress name the html writing area for this “class”.
Here you can see on the right of the “inner-post-entry”, 779.98 (is the max-width) is the actual size we are looking for. So you can resize your image that used in the writing area maximum width to 779.98 pixel. Because this is the maximum size that the image will be display on this area, even a 2k high resolution image will also be displayed in 779.98 px.
Therefore, fit every images on every position is one thing that can reduce the burden of your website while loading. But this is not the end, this until here you can only improve the image on your website about 75% of the optimization.
