Convert stm to png

What is the difference between .stm and .png?

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 PNG file is an image file stored in the Portable Network Graphic (PNG) format. It contains a bitmap of indexed colors and uses lossless compression, similar to a .GIF file but without copyright limitations. PNG files are commonly used to store graphics for web images.
