Digital Image

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.

For more information on the individual digital image formats, see their specific glossary entries: JPG (JPEG), GIF, PNG, BMP, PSD, and AI.
