What is the difference between .stm and .webp?

Description: The STM file type is primarily associated with PhotoStudio, a photo editing software developed by ArcSoft. It specifically refers to the PhotoStudio Stamp file, which is used to store stamp data or templates that can be applied to images within the software. These stamp files allow users to easily add pre-designed graphical elements, such as symbols, icons, or decorative motifs, to their photographs or projects. The STM format facilitates the customization and enhancement of images by providing a library of creative assets directly within the PhotoStudio environment.; 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.
