The 6 reasons for slowing the website speed (how to repair it)

Do you want to know why the image is loaded slowly on your website, or they take a long time for a long time Can I load it? You are reading the right article. Let us start with two important things: the picture occupies a large part of the website traffic, so optimization pictures help reduce the loading time. At the same time, images are usually the culprit of performance problems: they occupy loading resources, which is why they reduce the speed of WordPress website.

Why your image is loaded slowly (or always loaded forever)

1. The picture is too large (you may use too much)

When talking about the speed of the webpage, the first thing you should do is optimize your heavy image. The high -resolution of the larger size will occupy a large bandwidth and slow down the loading time of the visitors on your website -then why not upload them in a small size? And, don’t let your image quality affect! Use a reliable and effective application for image compression. This will ensure that when you reduce their size, they still maintain visual preservation, and the quality loss is small.

2. There are unspecified sizes in the picture

Properly zooming images are important for avoiding the loading time of website images. Don’t let the browser a zoom in you -this will give it more data to load. In other words, the browser will still load the entire image. If you have a 2000 X 2000 pixel image, but you have narrowed it to 200 X 200 pixels, your browser will have to load ten times more than the required capacity.

3. The picture is not performed according to the deviceOptimization In order to prevent the image loading slowly, your page should not show the version of the version displayed on the user screen. In short, anything greater than the device will cause waste bytes and slow down your page speed.

4. Browser starts to load pictures at one time

By default, your browser will try to load everything at the same time. If you do not give priority to the image that needs to be loaded first, the browser will be busy rendering them once. It is the most important image that needs to be loaded in the visitor’s viewport.

5. You use the heavy format

The size of the picture is only part of the problem. The type of file you use will also occupy precious space. Do you use formats like .tiff or BMP? In this case, remember that TIFF is an unprepared format that can present more detailed pictures and contain more data … This will create larger files and eventually occupy a large amount of storage space. If you do not use .tiff but use JPEG and PNG, you should know that you can use a lighter format, and you will find in the next section. A simple conversion can improve your image!

6. Your cache does not store images The main advantage of the cache image is Improve the performance of WordPress website. Users should directly view images or JavaScript and CSS files directly from his system instead of waiting for them to through the network. In other words, your image should slowly exist in a temporary local folder to avoid unnecessary ping database.
