It is impossible with HTML. The user will be able to choose any file. You could write code to block file types, but a user could bypass this.
The accept attribute specifies allowed files. Some examples:
Let’s see how to get file extensions in JavaScript. Use split() on the dot to convert the filename to an array. The extension is the last array item.
.html files are opened by specific applications. HTML is a language used to build websites.
The input element creates controls to accept user data for forms and web pages.
Create a form to check the file extension. It has an input for the file, a button to trigger the check, and a paragraph to display the extension. The JavaScript will get the extension and inject it into the result span.
