Image Fade Mask - Free Online | FunToolX

After uploading a picture, you can set the fade widths of the top, bottom, left and right edges respectively. The fading area transitions smoothly from fully opaque to fully transparent, producing a soft ablation effect. You can fade in only one direction, or you can fade in all directions at the same time to create a spotlight effect.

The implementation principle is to draw the original image on Canvas first, then superimpose a layer of linearly graded or radially graded globalCompositeOperation mask, and gradually reduce the alpha value of edge pixels to 0 through destination-in blending mode. All done locally in the browser.

It is suitable for soft transition of pictures, edge fusion of collages, and fade-out effect of web banners. It is also often used for social media avatar creation, allowing the edges of the image to naturally blend into the background color.

The online picture fade mask tool adds a fade transparency effect to the edges of the picture, and supports independent control of the fade range and shape in four directions: top, bottom, left, and right.
