The TUB file type is specifically associated with PaintShop Pro, a popular image editing software developed by Corel. It represents a Picture Tube, which is essentially a collection of graphic elements that can be used to decorate or enhance images within the program. These elements can include objects, decorative motifs, or even themed sets of graphics that users can "stamp" onto their projects with ease. The Picture Tube format allows for creative flexibility, enabling users to apply multiple instances of these elements across their works in a seamless and efficient manner.
A WEBP file is an image saved in the WebP (pronounced "Weppy") raster image format developed by Google for web graphics. It is designed to reduce image file sizes over standard JPEG compression while maintaining the same or similar quality. WEBP files allow images to be downloaded more quickly.
