Not yet: the tool stamps text (name, ©, notice) in a corner, in the center or tiled. For a logo, overlay it with the PDF editor after converting the image to PDF, or wait for the announced addition of this option.
It discourages theft and identifies the author, but it can be cropped out or retouched. A semi-transparent tiled pattern covering the image is harder to remove than a notice in a corner.
