What is an image file size?

Images are composed by several dots called pixels, and each of them has a color, represented as a combination of three basic colors (red, green and blue). To store each of these pixels, 3 bytes (24 ones or zeros) are generally used.

How can I reduce my image's file size?

One way is compressing the image, which reduces file size without having to resize it. Image quality will suffer as you increase compression and start losing more data.
