Image file size - GCSE Computer Science Definition

Image file size refers to the amount of digital storage space an image takes up on a computer or any digital device. It is measured in bytes, with larger sizes usually measured in kilobytes (KB), megabytes (MB), or even gigabytes (GB). The file size of an image depends on various factors such as its resolution (the number of pixels that make up the image), the file format (like JPEG, PNG, or BMP), and the level of compression used. Larger file sizes mean higher quality images but take up more space and may take longer to upload or download. Understanding image file size is important for managing storage space and ensuring efficient file sharing and uploading on the internet.
