Not only beginners but sometimes the masters also failed in selecting the appropriate image format type which results in slow loading of web pages.

The selection of the correct image format type is enormously important from the Search Engine Optimization point of view also.

Why I am saying this?

As per the new research by Google, it has found that if any web page takes more than 3 seconds to open then the particular website losses its 53% of users.

This is not the exact statement, words are different but has the same meaning.

Actually, this is not my statement, from time to time google always changes its algorithm to improve the quality of web pages.

In order to serve a great experience to the users, google always provides priority for the fast loading web pages. Though there are several factors that are responsible for the web page speed.

And the optimization of Images is one of the parts to improve the loading speed of a web page. We all know the importance of images for web pages, especially in blogs.

And this could be possible only when all possible file types are optimized and properly nested in your particular web page of blog and website.

So, In this post, I am gonna share the ultimate guide on the Best Image Size For Websites so that there will no issue on your website or blog regarding the slow loading of the web pages.

What is JPG and PNG?

Well both the JPG and PNG are a type of image format which are used to store the data of images in their respective formats. There are a lot of different types of images format are there like TIFF, BMP, PSD, PDF, and many others.

Each file type has its own importance and way of use but JPG and PNG are the most used formats. JPG stands for Joint Photographic Group while PNG stands for Portable Network Graphics.

What’s better jpeg or png?

First, of all let me tell you that JPG and JPEG have no difference at all JPG stands for Joint Photographic Group whereas JPEG stands for Joint Photographic Expert Group.

Actually, the only difference between jpeg and jpg is the number used in the characters. In the earlier version of windows, only three characters are required for the extension of the file name. That’s why JPEG was shortened to JPG.

Now coming to the point, which is better JPG or PNG for web?

To decide the better one we need to look the following things in it:

  • The file size should be small.
  • The image should be clear to the user.

JPG or JPEG images file format has low-quality pixels stored in it which results in small file types, means these type of images are smaller in size compared to PNGs.

JPG file types have lossy compression algorithms that compressed the image to provide an optimal sile size.

Whereas PNG image file format has high-quality pixels stored in it which results in a large file type, also it uses a lossless compression algorithm that means image data are not compressed.

That is the main reason PNG images have high quality and mostly used where there is a need for high-resolution pixel. Generally, PNG has a transparent or semi-transparent background.

So, if the images will be used on websites or blogs then only small files are good but if you don’t need images for the blogs and websites you can go with your choice both are good.

Recommended Image Format for Website use

If you are thinking to use JPG image format on your blog or website then you can use it there’s no problem with it.

But from the SEO points of view, most of the blogs and website doesn’t load faster then there’s only one reason and that is web page has the large file size for which the server is unable to respond faster.

There are several factors involve in this maybe there is a lot of CSS and JAVA code are present which need to be minified and removed. And might the images have a large file size?
