Hello and thank you for posting on InPixio blog.
Before clipping out an object make sure InPixio is updated to its latest version released.
Use both tool: mark to remove and mark to preserve to receive better cutting quality of the object. For images with more details zoom in closer in the picture to see the edge of the object and use smaller size brush to mark the safe area border.
Inspect the clipped image before saving it and montage it over another image.
Kind regards,
The InPixio Team
