You can compress image by using this method.
function compressImage(imageUrl) {
let image = new Image();
image.onload = () => {
let canvas = document.createElement('canvas');
let maxSize = 1504; // Define Size of Image
let width = image.width;
let height = image.height;
if (width > height && width > maxSize) {
height *= maxSize / width;
width = maxSize;
} else if (height > maxSize) {
width *= maxSize / height;
height = maxSize;
}
canvas.width = width;
canvas.height = height;
canvas.getContext('2d').drawImage(image, 0, 0, width, height);
let base64Image = canvas.toDataURL('image/jpeg').split(",")[1];
}
image.src = imageUrl;
}
