To begin with, let’s briefly define, why optimization (which is another word for compression) of website images is necessary.
Everyone knows that the acceleration of the site improves the behavioral factors, and raises the conversion of the site (sales growth).
Here is an example of graph of the conversion of load time, which is based on the study of Walmart.
The graph shows that the more time that page loads, the less customers make targeted actions on the site. If your site is not working as fast as possible, then you are missing out on potential profit. Website acceleration will improve conversion and thereby gain more potential customers and increase revenue.
A webpage usually consists of:
If you look at the picture in the middle section, and compare the amount (in bytes) of all of these types of resources on the page, you can see that the part containing images is the biggest part (containing the largest number of bytes).
Obviously, the optimization (reduction) of the images can significantly speed up the loading of the site.
We have identified the problematic part - due to the large volume of images the entire website loading slows down. Thus, if you reduce the volume of images on the site, the pages of your site will load faster.
Optimization (compression) of the images is exactly what allows reducing the image volume by 70-98% without loss of visual quality of the images.
And now let’s take a closer look - what the optimization of images means, and how image optimization speeds up the site.
Optimization (compression) of images - is the processing of the file in order to reduce its size (in bytes), preferably without loss of quality.
To do this, there are many complex algorithms. Their core principle is about the same - all service data are deleted from the file (name of the program, which saves the file, etc.), also similar colors are united/smoothed in a special way.
The resulting image is absolutely the same and no changes can be seen in it.
But the size in bytes of this optimized image will be many times smaller than of the original.
With proper processing, you can get up to 70-98% smaller file with no visual loss of quality.
You can manually optimize each image on the site. You can use Photoshop or another tool. Normally, when you save an image in the editor, there is an option "save for web".
But this means huge amount of wasted time (especially if you have not only hundreds, but thousands of images on the site).
Each image will have to be restored manually and uploaded to the site.
It will surely take much of either your own time or the time of your employees. Either way it will require certain resources and, therefore, financial spending.
OptiPic.io Service is specifically designed to solve this problem.
In just 2 minutes you will be able to connect your site to a system that will scan the entire site, find and optimize (compress) all found images.
Optimization of all images on the site continues to perform its operations automatically in the background.
The service will find all the images on the website and optimize them by itself.
And when you add new images to the site in the future (or change old images), they all automatically be queued for optimization. The system monitors these changes itself and reacts to them.
OptiPic easily connects to any site in just 2 clicks.
Supports all CMS and frameworks as well as self-made engine sites in PHP.
You are welcome to evaluate the optimization efficiency on OptiPic.io website. It is free of charge and requires no registration.
