What is .htm?

.htm is a file extension used for web pages that contain HTML (Hypertext Markup Language) code. HTML is used to create the structure and content of websites. When a webpage is created in HTML, it is saved as an .htm file on the server. Web browsers such as Google Chrome, Mozilla Firefox, Microsoft Edge, and Safari use HTML to render websites for display on devices. HTML provides a way to add content, images, videos, links, and other media to a webpage. .htm files can be edited using any text editor or web development software such as Notepad, Dreamweaver, or Visual Studio Code.
