How to Verify that an URL is an Image URL using JavaScript

In this short article, we will show you how to verify that an URL is an Image URL using JavaScript.

Here, we will use the Regular Expression to validate the image url using JavaScript.

Use the following function to check the extension using a regular expression.

Function

function checkURL(url) {
  if (typeof url !== 'string') return false;
  return (url.match(/\.(jpg|jpeg|gif|png)$/) != null);
}

Here we have validated the extension such as jpg, jpeg, gif, and png. This function will return the boolean value.

Output

checkURL('codepremix.com'); // Output: false
checkURL('https://xyz.com/abc.png'); // Output: true
checkURL('http://abc.com/xyz.gif'); // Output: true

In the upcoming article, we will show you how to check if an image exists from a URL.

That’s it for today.
