JavaScript - convert base64 to string

In this article, we would like to show you how to convert Base64 to string in JavaScript.

Quick solution:

// ONLINE-RUNNER:browser;

const encoded = 'c29tZSB0ZXh0Li4u';

const decoded = atob(encoded);
console.log('Converted text: ' + decoded);  // some text...

Practical Example

In this example, we use atob() method to decode Base64-encoded ASCII string.

// ONLINE-RUNNER:browser;

const encoded = 'c29tZSB0ZXh0Li4u';

// convert base64 to string
const decoded = atob(encoded);

console.log('Base64 text:  ' + encoded);  // c29tZSB0ZXh0Li4u
console.log('Decoded text: ' + decoded);  // some text...

Output:

Base64 text:  c29tZSB0ZXh0Li4u
