Reducing the size of an image vs. compressing a file
There is an important difference to understand between the process of shrinking an image to make it smaller and the process of reducing the size of a file without changing the image. The latter is what the term file compression refers to, and it is very important for image files that take up a lot of disk space. The goal of compression is to reduce the size of an image file while minimizing the effect of this change on the image itself.
The uses of image file compression
Image file compression is a valuable tool in many situations. For example, if you are working with a high-resolution image, the size of such a file is very large, and this might make it difficult for you to share the file via email. Fortunately, image file compression tools are available to reduce the size of the file so that you can upload it as an attachment.
