If there are a lot of images on a website, the browser has to download them one by one and load the website. Therefore, it takes a long time for a website to be fully loaded and this reason alone is enough for users to leave the website and this leads to an increased bounce rate.
To prevent this from happening, as the webmaster it’s your responsibility to optimize images to reduce the loading time of the website. According to Google algorithms, the speed of a website is very important in SEO, and images play an important role in this factor.

Based on the reasons we mentioned to optimize images for SEO, it’s time to discuss what factors you need to take into consideration when optimizing images for SEO.
Optimize Images by Changing the Size and Dimensions

Often, high-quality images are taken by professional cameras and due to the high resolution, the sizes are relatively big. These images are usually used in printing. However, to add them to a website, you have to compress them without losing the quality.
There are a lot of methods to compress an image. We will mention a few down below.
Choose the Most Optimized Image Format

- Never use the GIF format for relatively large images. This format increases both size and dimension and will slow down the website. Use this format for thumbnails.
- PNG can be used instead of both GIF and JPEG. If you are going to use PNG for a product, make sure you use PNG-8 instead of PNG-24.
Choose the Right Compression Rate for Your Images
Compressing an image is one of the necessary steps in optimizing for SEO. If you compress an image way too much, it decreases the size sure. However, it loses quality. On the other hand, if you don’t compress them right, they may be way too large to be added to a website.
