I am trying to crop product photos and add a solid white backdrop to the photos. I am cropping the photo, then using the Free Hand Selection Tool to cut out the image. I then delete the background and change it to white. However when i export the image file there is a gray line surrounding the image. Even if i use the Pixel Tool to change the border pixel by pixel to white, when i reexport the image, the gray line still surrounds the image.
any tips on getting rid of the surrounding line?
