Make it your habit, because Google pays attention to this! As for the average user, it is very important that the site is loaded very quickly, and for Google metrics, the moment of optimization of images is very important, since this affects the ranking in the SERP. When creating a new site, the webmaster should optimize all the images so that you get a site that is quickly loaded and has no problems with Google. But what about next? It’s simple! You should take it as a rule to compress all the images before uploading to the site. The first stage of compression is the fit of the desired image size. Very often it happens that for the site the photographer provides images in high resolution from 5000 pixels and weight more than 5 megabytes. Such images must first be reduced in a visual editor. The maximum recommended image size for uploading to the site is not more than 2200 pixels. Such a picture will look good on the retina display. If the image is not used on a large scale, then the size should be done as little as possible, but keep in mind that your site will be viewed from the retina. We have a picture of the appropriate size, what’s next? Further it needs to be compressed and, preferably, without loss of quality. For compression, you can use the following online resources. So, 3 useful resources for image compression:
  1. Tinypng  
  2. Jpegmini  
  3. Optimizilla Of all the three, I would recommend optimizilla, it is more versatile and works with a group of images. Approximate percentage of compression without loss of quality is 60%. Just imagine that your page with a lot of photos will be downloaded 60% faster, which will not only bring convenience to your visitors, but Google will not lower such pages in the issuance because of the volume.
