A file name that identifies the file's type and indicates the application that created it typically includes a file extension, which is a suffix added to the base name of the file, preceded by a dot. For example, a file named "document.docx" indicates that it's a Microsoft Word document. The ".docx" extension specifies the file type and suggests the application used to create it. Other examples include ".xlsx" for Excel spreadsheets and ".jpg" for image files.
The extension is actually immaterial. It merely serves to give the operating system a hint as to the file's content, allowing the file to be associated with a particular application, such as a GIF file viewer or an image editor application. In order to save a GIF file, you must first re-encode the image (assuming it is not already in GIF format), and save the output to a file with a GIF extension.
