Png edge refiner tool What is a png edge refiner?
This browser-based utility allows you to defringe the edges of transparent PNG images and make the edges smooth. When the background in regular photos is removed, the pixels from the removed background often remain at the edges of non-transparent regions. This program corrects these pixel inaccuracies. It makes the pixels on the edges smooth and removes the pixel border that's left from the background. Such smoothing helps to make the outline of a PNG very clear. The program is fully automated and you don't need to select the boundaries in the PNG yourself. You just need to upload a PNG to the input field and adjust the edge smoothing radius in the options. The larger the radius, the more pixels at the edges are made semi-transparent (or completely transparent, depending on the radius). If your photo still has a background, then you can remove it using our Remove PNG Background tool. If you want to add a new background to your PNG after refining the edges, you can use another of our utilities – Add PNG Background. Png-abulous!

Remove Wall Clock Outline
In this example, we remove the black outline around a wall clock that leaked through from the old background when it was deleted. To completely clean up the black pixels on the boundary between the clock and the transparent background, we set the cleanup radius to 3 pixels (in the radius option) and this value successfully produces a defringed clock PNG without the black outline.

Make PNG Border Smooth
After removing the sky background from this PNG photo, a bunch of blue sky pixels were still left at the border between transparency (new background) and opacity (photo itself). To fix this border issue and to completely remove the leftover pixels, we smoothed the pixels at the border over a radius of 4px. As a result, we got a transparent overlay of a bird that we can put over another photo or add a new background to it if we want to. (Source: Pexels.)

Refine Edges of a Signature
In this example, we removed the white pixel artifacts around Benjamin Franklin's signature. All we had to do was use a 1-pixel radius for refining the edges. Our program then automatically ran the edge refinement algorithm on the PNG signature file. The new signature can now be used electronically to sign documents and can be put in PDF and Word documents. (Source: Wikipedia.)
