If you don’t intend to use this information, you can remove this information which will reduce the file size of your image. Note that you won’t see a significant difference in your image’s file size, as the metadata usually doesn’t use too much space.

With various methods outlined above, you can quickly and easily reduce the file size of any of your images. You can either use web-based tools if you don’t like installing apps, or use installable programs to compress your images.
