What it does
BgSub removes and replaces image backgrounds, with color, gradient or image backgrounds and size, position and mirroring controls.
After removing the background, choose a colour, gradient or image replacement and adjust the subject's size, position or mirroring to fit. Automatic colour adjustment is also offered. BgSub presents the tool as free and states that images need no upload. Its returned FAQ does not answer the resolution, commercial-use or API/batch questions, so those capabilities should be checked separately before choosing it for a repeated production job.
