This browser-based utility removes unwanted outlines from PNG objects. It removes white, black, or any colored outlines by turning their pixels to transparent background. You can precisely define the width of the outline you want to erase in the options. A small outline width will remove a thin line of pixels on the edges of elements, while a large outline width will erase a thick line of pixels around the objects. If in some places, the outline has a large width and goes deep into the crevices of objects, you can enable the "Advanced Outline Cleanu" mode. It operates by searching for pixels of the same color as the removed outline deep within PNG elements. Here, you can specify the outline removal color threshold, which assesses the similarity of the removed pixels' shade. The color threshold can be calculated using the "Nearest Euclid Color" or "Nearest Visual Color" algorithm, which you can switch between in the options. You can also specify the outline removal depth, determining how deep into the crevices to remove outline pixels. After clearing the PNG of outlines, you can smooth the edges of all elements. By specifying the pixel smoothing radius in the options, you make the pixels at the edges semi-transparent. Additionally, you can customize the outline removal area by enabling or disabling the outer contour matching option. If this option is active, the program focuses only on those areas of objects that serve as the external edges of elements, leaving the internal transparent regions untouched. Png-abulous!

In this example, we remove a thin blue outline around a green apple in a PNG image. We set the outline width to 8 pixels, which causes the program to make the pixels on the edge of the apple 8 pixels deep completely transparent. We also set the smoothing to 3 pixels, which causes the program to make the 3 outermost lines of pixels on the apple semi-transparent. (Source: Pexels.)
In this example, we remove an orange outline around candy canes in a ceramic cup. To completely delete the orange outline, we use regular outline removal with a width of 11 pixels, and we also apply advanced outline cleanup. The advanced cleanup reaches up to 100 pixels deep into the gaps and removes pixels that are 16% similar in color to the main outline color (according to the "Nearest Euclid Color" algorithm). The outline is only removed from the outsides of the candy canes and the cup, as we use the match outer contour mode. (Source: Pexels.)
In this example, we remove a glow around a man's portrait using the outline removal program. Since the glow is wide, we set the outline width to 40 pixels, and we also perform deep pixel removal with a "Nearest Euclid Color" algorithm with a threshold of 16% and a depth of 100 pixels. We also use the match outer contour mode and perform 1-pixel smoothing around the edges. (Source: Pexels.)
