This website allows you to upload a background and a foreground image, blend them using alpha blending, and apply
various filters such as grayscale, sepia, saturate, and invert. You can also adjust brightness and contrast, apply
effects like smooth, sharpen, gradient, and Laplacian on the background image, and download or reset the canvas. Use
the sliders and radio buttons to modify the image, and click the 'Save' button to download the final result.
