Optimising

When displaying images on the Internet, there needs to be the correct balance between the file size and the quality of the image. Normally, when a webpage is loading it is due to the images on that page, and this is why it is important to get the correct balance, as you don’t want the webpage to take a long time to load but also want the image to be of a good quality. There are certain areas within an image that can be reduced slightly in order to decrease the file size, such as the bit depth, resolution and the dimension of the image.

There are also several other ways that can help to reduce the file size of an image but keep some of the quality. There are different formats in which an image can be saved as in which some have smaller file sizes than others. The two main formats that are generally used are GIF’s which should be used for simple line drawing that are not too complex and the other is JPEG’s which should be used for photographs. There are other techniques that can be applied as well such as cropping out certain areas of the image that are not needed; this will help reduce the size.
