Large images can dramatically reduce the speed of your site and diminish the impression the site has on visitors. Visitors will tend to wait only 3 to 5 seconds for a website to load.
Whether you are working on your website, your Facebook page or an e-commerce site you want to make sure the images you post are optimized for speed. The faster your website appears in full, the faster your visitor can find what they are looking for and that could mean sales for you.
To fix the problem of large images that slow down your site it will be necessary to reduce the image’s resolution by applying compression that will make the image size smaller but have no loss to the quality of the image. This process is called optimizing an image.
First, it is smart to save your large original images in a safe spot on your hard drive or online. Then you can work with a working version that you edit and rename. If you don’t have Photoshop you can find free optimization software by searching reducing image size or image optimization.
But only certain types of images can be optimized. You won’t be able to optimize pictures that have a drawing type of format (vector graphics) such as .wmf, .emf, and .eps.
But you can optimize high-resolution images, such as photographs. File types like these are good candidates .png,.jpeg or .jpg, .tiff, .bmp, and .gif.
