DOT is a template file format used by Microsoft Word for creating documents with a predefined layout and formatting. DOT files allow users to create consistent document designs, making them ideal for reports, letters, and business correspondence. They can be customized and saved as regular DOC files for further editing.
PNG is a lossless image format that supports transparency, making it ideal for logos, icons, and web graphics. Unlike JPEG, PNG doesn’t lose any image data during compression. It retains high-quality detail, especially in images with sharp edges, and is commonly used for design work where transparent backgrounds are required.
