The image format provides a standardized method for organizing and storing image data.
The image format can save images as raster (uses pixels) or as vectors.
The file size of an image, expressed in bytes, increases in tandem with the number of pixels in the image and the color depth of the pixels. A pixel depth of 8 bits (1 byte) allows 256 colors and a pixel depth of 24 bits (3 bytes) can store more than 16 million colors (called true color).
Image compression is a method of decreasing the amount of byte size an image file occupies. For example, an image taken at 8 megapixels will occupy 24 million bytes of storage (about 23 megabytes). This is too much for an image, for this problem there are different image formats and different compression algorithms that they use.
Graphics compression can be lossy and non-lossy. Compressing a lossy image will cause it to lose quality, but generally offer better compression than lossless techniques.
