What is what are pictures with no background called?

Pictures with no background are called transparent images or PNG (Portable Network Graphics) images. They are graphics that are saved in a way that allows them to have a transparent background, meaning that the background of the image is see-through. Transparent images are commonly used in graphic design, web design, and other creative projects, as they allow for easy integration with other elements and backgrounds. They can be created using specialized software such as Adobe Photoshop or online tools such as remove.bg.
