In one of our previous posts, we had provided some simple tips to speed up a website.
It concludes that compression facilitates the reduction of the image size hence, making it optimized for the website. Now, here at Templatetoaster offline website builder software, let’s discuss some of the popular image compression software tools available on the Internet, to help you for speeding up your website!
What are Image Compression Software Tools?
Image compression is a method where data is compressed especially, digital images in order to cut down the value of transmission and storage size. There are several such tools available which can help websites in their smooth loading.
These tools help in pacing up a website’s functioning. In fact, research shows that for every additional second a website takes to load, it witnesses a prominent loss in the conversions. Therefore, these tools are a must when it comes to balancing the load speed and in turn, maintaining the SERP ranking. As it seems like a “ranking factor”, suggested by Google.
“To make our results more useful, we’ve begun experiments to make our index mobile-first. Although our search index will continue to be a single index of websites and apps, our algorithms will eventually primarily use the mobile version of a site’s content to rank pages from that site, to understand structured data, and to show snippets from those pages in our results. Of course, while our index will be built from mobile documents, we’re going to continue to build a great search experience for all users, whether they come from mobile or desktop devices.
If you have a responsive site or a dynamic serving site where the primary content and markup is equivalent across mobile and desktop, you shouldn’t have to change anything.” – GOOGLE
