First, you need to create two Files one HTML File and another one is CSS File. To create this program (Preview Image Before Upload). Through the FileList object, you can get the name, size, and contents of the files. The file property returns a FileList object, describing the file or files selected with the file upload button. This program is only possible with the JavaScript files object. There is also shown a cancel button (cross-sign) and when you click on that button, the preview file which you selected will be hidden or canceled. And when you hover on the file, the name of that file will appear on the bottom side of the preview container. After selecting the file, the preview of that file is shown on the preview container. When you click on the choose a file button there will open a new window to select an image or file. In this program, at first, on the webpage, there is a file preview container with a cloud icon and an upload button. And now I’m going to create a File Upload Button.
