Hello there, young technologists! Today, we’re going to explore something really cool – creating your very own Image to WebP Converter Tool. Don’t worry; it might sound fancy, but we’ll make it super simple, and you’ll have a fantastic tool to convert images in no time!

Why WebP?

Firstly, let’s talk about WebP.
On the internet, images look fantastic thanks to this unique image format.It’s like turning your favorite photos into internet superheroes with superhuman speed. S

What You’ll Need

To make this magic happen, we’ll need HTML, CSS, and JavaScript.. Think of them as the building blocks of our tool. HTML makes the structure, CSS makes it look awesome, and JavaScript adds the smarts.

Step 1: Building the Base (HTML)

Imagine the HTML part as the foundation of a house. Here’s a simple start:

<!DOCTYPE html>
<html lang="en">
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Image to WebP Converter</title>
  <link rel="stylesheet" href="styles.css">
  <div class="container">
    <h1>Image to WebP Converter</h1>
    <input type="file" id="imageInput" accept="image/*">
    <button id="convertButton" class="green-button">Convert to WebP</button>
    <div id="output" class="image-preview"></div>
  <script src="script.js"></script>

Step 2: Making It Look Awesome (CSS)

After that, let’s style it with CSS. It’s like giving our tool a fancy coat. Here’s a start; you can make it even cooler:

body {
  margin: 0;
  font-family: Arial, sans-serif;
  background-color: #f0f0f0;

.container {
  max-width: 600px;
  margin: 0 auto;
  padding: 20px;
  background-color: white;
  border-radius: 10px;
  box-shadow: 0px 0px 10px rgba(0, 0, 0, 0.1);

h1 {
  text-align: center;

input[type="file"] {
  display: block;
  width: 100%;
  margin: 20px 0;

.green-button {
  background-color: #00cc66;
  color: white;
  border: none;
  padding: 10px 20px;
  border-radius: 5px;
  cursor: pointer;

.image-preview {
  text-align: center;
  margin-top: 20px;

.image-preview img {
  max-width: 100%;
  border: 1px solid #ccc;
  border-radius: 5px;
  box-shadow: 0px 0px 5px rgba(0, 0, 0, 0.1);
  display: block;
  margin: 0 auto;

Step 3: Adding the Brains (JavaScript)

Now, it’s time to add the smarts with JavaScript. This part listens to what you tell it to do. We’ll use it to convert images to WebP format. Here’s how it could begin:

const imageInput = document.getElementById('imageInput');
const convertButton = document.getElementById('convertButton');
const output = document.getElementById('output');

convertButton.addEventListener('click', async () => {
  if (!imageInput.files.length) {

  const imageFile = imageInput.files[0];
  const image = new Image();
  image.src = URL.createObjectURL(imageFile);

  image.onload = async () => {
    const canvas = document.createElement('canvas');
    canvas.width = image.width;
    canvas.height = image.height;

    const ctx = canvas.getContext('2d');
    ctx.drawImage(image, 0, 0);

    const compressedWebP = await convertToWebP(canvas, 0.1);
    const webPImage = new Image();
    webPImage.src = compressedWebP;

    output.innerHTML = '';

    const downloadButton = document.createElement('a');
    downloadButton.textContent = 'Download WebP';
    downloadButton.href = compressedWebP; = 'converted_image.webp';

async function convertToWebP(canvas, quality) {
  return new Promise((resolve) => {
      (blob) => {

Bringing It All Together
