What is a Digital Image?
A digital image is an image or photo which exists in a non-physical, computer readable format. Digital images are stored on a hard drive in binary format as ones and zeroes. When processed for display the binary code is translated into a set of instructions used by the computer or device to display a pixel-based image. At its core, a picture displaying on a devices monitor or screen is a compilation of data including both color and location information.
There are multiple different digital image formats in use today. The most widely used formats are: JPG (or JPEG), GIF, and PNG. Other notable digital image formats include BMP, PSD, and AI.
Each different image format provides a particular set of benefits and, conversely, drawbacks. Your specific use case will determine the format of digital image needed.
