We can use Cropper.js to crop images in expected shape. With the help of the node package manager we can install the Cropper.js package.

$ npm i cropperjs

<link  href="/path/to/cropper.css" rel="stylesheet">
<script src="/path/to/cropper.js"></script>

Or

import Cropper from 'cropperjs';

Enable Cropper.js on the image or canvas element.

const cropper = new Cropper(image, {
  dragMode: 'move',
  aspectRatio: 16 / 9,
  crop(event) {
    console.log(event.detail.*);
  },
});

Another way is with the help of canvas element drawImage() method.

/* Get Canvas element */
var canvas = document.getElementById('canvas');
var ctx = canvas.getContext("2d");

canvas.width  = image.width;
canvas.height = image.height;

/* Reshape / Crop Image */
ctx.drawImage(this.imageObj, 0, 0, 50, 50, 0, 0, 50, 50);

//Syntax
drawImage(
    image,
    sourceImageX,
    sourceImageY,
    sourceImageWidth,
    sourceImageHeight,
    destinationCanvasX,
    destinationCanvasY,
    destinationCanvasWidth,
    destinationCanvasHeight);
