Welcome folks I am back with another blog post. In this post we will be implementing How to Preview Image Before Upload using Javascript from scratch. Image Preview is one of the most important features when it comes to image uploading. In this post we will be implementing this feature in the following steps.

 

Make a new index.html file and copy paste the below code. In this code we have just a file upload button.

 

 

Make a new preview.css file for the stylesheet. It will style the application.

 

 

Make a new preview.js file. This file will hold the logic for the preview image which will be displayed to the user before image upload.
