What are the advantages of using <canvas> element in PHP for image manipulation and marking?

The <canvas> element in PHP allows for dynamic image manipulation and marking directly within the browser, without the need for server-side processing. This can greatly improve performance and reduce server load when working with images. Additionally, the <canvas> element provides a flexible and customizable way to interact with images, making it ideal for tasks such as adding watermarks, annotations, or other graphical elements to images.
