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. When an image is large, it may have millions of pixels, and that means storing all information for an image like that in a computer or any device will take millions of bytes.
When a camera or cellphone says it takes 10 megapixels photos, it means that each photo has 10 million pixels (mega = million). And having 10 million pixels means it takes 30 million bytes (or 30 megabytes) to store that photo (which is a lot of space!). If you want to send this photo (or many photos) to a friend by e-mail, it will have to transfer 30 megabytes of data and it will take a while to upload it and a lot for the recipient to download it later.

How can I reduce image file size?
Is there any solution? Yes, there are two main solutions. One of them is compressing the image: compression reduces file size without having to resize the image, but image quality will suffer as you increase compression and start losing more image data.
Resizer
The other solution is to resize your photo, decreasing the number of pixels it takes to store the image, which reduces it's file size proportionally. Reducing image size doesn't reduce image quality, although it may lose some very small details if they become too small.
Photos taken using modern cellphones and cameras usually have over 6 million pixels, while most cellphones, tablets, notebook or TV screens have only about 1.5 million pixels, which means you end up seeing a resized version of the image (you only use the full image if you print it). So if you resize your image, decreasing its width and height to a half, your image would have about the same number of pixels than the screens that will display it, so you wouldn't be losing any quality or detail at all, even looking at your image in full screen mode.
So remember, if you have a huge photo, you can reduce its file size by resizing it until it's about 1900 by 1100 pixels, and getting a JPG image with just a little compression (about 95% quality). Doing so, you will get a versatile image with great quality, that you can send to anyone without taking too much time, or spending too much bandwidth on your mobile data plan.
