Web images take up most of the download time in viewing web pages. But if you optimize your web images you will have a faster loading website. There are many of ways to optimize a web page but keeping your images as small as possible will relevantly improve the speed of your website. A good rule of thumb is to keep the total size of your web page including all images, HTML, CSS, and JavaScript no larger than 100KB.

To do this, you need to have graphics software to edit your images. You can get a graphics editor or use an online tool like Photoshop Express Editor or JPEGmini.
