Generative art defines a process where the creator sets rules (usually in a text sentence) that are then actioned by artificial intelligence. Often, the creator then refines the image. The art form combines artistic expertise and algorithmic serendipity.
This is a new art form and there will be technological advances, so watch this space. Try these six generative art applications. There is no charge – unless you get hooked! Most require you to open an account before downloading to reduce hacking opportunities.

PNG ('P-N-G') is preferred for NFTs because the image is designed to be displayed on-screen. The advantage of a PNG is that there is no loss of quality when you compress the file size, which is often necessary to ensure a fast loading time or to reduce dimensions. PNG is not suitable for printing purposes as it does not support the CMYK color scheme.
JPEG ('JAY-PEG') files are entirely suitable for general on-screen use. It is best used when file size is more important than having a very high image quality. A typical JPEG image has a 10:1 compression ratio, which means that if you export a 10MB image as a JPEG, your final image will be about 1MB. However, JPEG images are lossy, which means that after the image is saved, the data lost during the compression can’t be recovered. This is not an issue in many cases but does need to be considered if the image is to become an NFT.
SVG ('S-V-G') files are increasing in popularity for on-screen images. These are vector files. SVG images are scalable, can be printed with high quality at any resolution, and hold quality if they are zoomed or resized. They are crisp on any screen and also small in file size.
Image resolution refers to the amount of detail in an image. Higher the resolution, the more detail in the image.
Images on-screen are made of squares called pixels. The usual screen resolution is 72 pixels per inch (ppi). If an image is less than 72ppi, it will appear fuzzy or pixelated. There is considerable debate about whether the resolution really matters for an on-screen image because the best display resolution depends on the size of the viewer’s screen.
However, image resolution does affect the size of a printed image.
Dimensions refer to the height and width of the image. There are no ‘standard’ dimensions for an on-screen image.
Square is very fashionable at the moment because social media profiles use it. A square NFT can be used as a person’s profile picture. Blocks of solid colour are popular backgrounds for the same reason. The image looks crisp when resized.
- Square - 1080px by 1080px or smaller.
