What is image optimization?

It also helps reduce the number of people who leave your site quickly saves server storage and bandwidth and increases the number of people who do what you want them to do on your site.

To optimize images you need to choose the format.

There are a few formats you can use:

* JPEG is good for photographs and colorful images. It makes the file size small. Still keeps the image looking good.

* PNG is good for logos and images with backgrounds.. It makes the file size bigger than JPEG.

* WebP is a format to use for modern websites because it makes the file size small and the image still looks good. It also loads faster than JPEG and PNG.

* SVG is good for logos and simple illustrations. It is a vector format so it looks good even when it is big and the file size does not get too big.

Before you upload images to your website you should make them smaller. A lot of people upload images from their phone or camera but these images are often too big. You should make your featured images about 1200 x 675 pixels and your other images about 800-1000 pixels wide.

You should also compress your images. Compression is when you remove data from an image to make the file size smaller. There are two kinds of compression: lossy and lossless. Lossy compression makes the file size smaller. The image does not look as good. Lossless compression keeps the image looking good. The file size is not as small.

You should use image formats like WebP and AVIF because they compress better than old formats. This helps your website load faster and use bandwidth.

When you upload images you should give them names. This helps search engines understand what your images are about which can improve your image search engine ranking. For example of naming an image "IMG_4587.jpg" you could name it "website-speed-optimization.jpg".

You should also write alt text for your images. Alt text is a description of an image that screen readers can read. It should be natural, accurate and relevant to the image. For example of writing "image1" as the alt text you could write "Laptop displaying website speed optimization tools".

Another thing you can do is enable loading. Lazy loading is when your website only loads images when the user scrolls near them. This helps your website load faster and use data.

You should also use images. Responsive images are images that change size depending on the device the user is using. This helps your website load faster and look better on devices.

Do not use many big images on one page. This can make your website load slowly. Instead use the images you need break up long articles into sections and use simple graphics instead of decorative images when you can.

Using a content delivery network (CDN) can also help. A CDN is a network of servers that stores copies of your images. When someone visits your website, the images load from the server that's closest to them. This helps your website load faster and use bandwidth.

If you use WordPress there are plugins that can help you optimize your images. These plugins can compress your images convert them to WebP and enable loading.

After you optimize your images you should test your websites speed regularly. You can use tools like Google PageSpeed Insights, GTmetrix and Pingdom Website Speed Test to see how fast your website is loading and find ways to make it faster.
