File type: Adobe Illustrator File


The AI file extension is a type of vector image specifically created with the Adobe Illustrator image editing application. This file format is made up of paths or lines connected by points as opposed to bitmap data which includes text, color, and objects.

It is a type of illustrator drawing that can also be accessed with other applications developed by Adobe like Photoshop.

However, when opening the image with programs like Photoshop, it is converted into a raster image which essentially transformed it from a vector image format to a bitmap file. In computing terms, vector graphics like the AI file extension utilize geometric primitives like curves, lines, points and polygons in representing computer graphic images.

These shapes are all established through mathematical equations. This graphics type is complementary to raster formats which represent pixel arrays and is normally associated with photographs. Vector images are more applicable when creating drawings and shapes.

It uses the mathematical formula in attempting to reconstruct the image on the computer screen.
This is usually achieved by producing the best possible quality image based on the given screen resolution derived by the mathematical data. The mathematical formula determines where the dots on the computer screen would be placed in order to achieve the best result in displaying the image represented by the AI file extension.
Essentially, the dots are arranged by the formula in such a way that the lines would be as clear as possible. In vector graphics like the AI file extension, the formula produces images which are scalable to practically any detail and size. The quality of the displayed image is dictated by the maximum resolution supported by the computer monitor including the file size of the vector data that would be required to generate the same image.
Printing this image on paper would produce a sharper image with a higher resolution compared to its onscreen representation.
