Image background remover

This tool removes the background from an image, leaving only the foreground objects. It uses a color-based background detection algorithm, gathering data about the color to be removed either by clicking on the background in the input preview or by specifying a color in the options. In the "Color Threshold" text field, you can specify a range of colors that will be considered part of the background. For example, if you set a color threshold of 10%, all pixels that differ from the background color by less than 10% will be removed. To avoid accidentally removing color areas within the foreground objects, you can enable the "Remove Outer Background" option. It instructs the algorithm to scan along the edges of the image and remove the background areas that directly touch the image borders. Since the image background is usually characterized by a smooth transition of pixels from the foreground to the background, after removing the background, some remnants of its shade may remain on these "transition" pixels. Therefore, to completely remove background remnants at the edges of the image, you can use the "Smooth Background Edge" option by specifying any edge smoothing radius. To check the transparent areas of the image, you can use the "Black and White Preview" option, which shows the transparent background in black color and the opaque foreground objects in white color. You can also choose to download the image in either of the two formats that support transparency – PNG and WebP. And for the reverse action, i.e., adding a background to the image, use the Add Image Background tool. Image-abulous!
