Consist of grids of tiny dots called pixels
Have a fixed resolution and cannot be resized without altering image quality
Edited in paint programs

Native File Formats: file formats that are default file format that are proprietary to a specific program that are generally not meant to be used with other software.
Standard File Formats: file formats that can be used with a variety of software programs. Standard file formats are usually created by using the “Save As” command or through exporting. Standard file formats include, but are not limited to: .gif, .jpg, .png, and .tif.
