Don’t be embarrassed to admit that you don’t fully understand image size. Most people don’t! The truth is that it is a little more complicated than it may seem, so we will break it down to the basics for you.
The size of the image is measured not in centimeters or inches, but rather in pixels. Each pixel is a tiny digital dot of information, and together they make up an image.
A computer can count the number of pixels in the height and width of an image. This is what gives us the image size. It is impossible to count pixels by eye as they are far too small.
The image size is determined when the image is created. The higher quality camera you use, the larger the image size it can create. Many cameras also give the option for you to select the default image size. This can be convenient as you can set it up according to your needs.
Large photographs take up more space on a memory card or a hard disk drive. If you select to create smaller photographs, you can fit many more of them on the space you have available.
For others, large photographs can be useful if they are to be used in billboards or large-scale advertisements. In this case, a large-size photograph would maintain its image quality even when it is printed on a big surface.
Images that are created on a computer or software program may also vary in size. In most cases, the user is given the option of what size he or she would like to save the image as when it is completed.
Once an image has been created, it cannot be increased in size because a computer program cannot fill in missing pixels or “information” that was not previously there.
However, it is easy to reduce image size using photo resizer, and that is where our online image compressor comes in.
