Edge Refinement
Clean, Natural Cutouts with Precision Tools
Posternity’s Edge Refinement tools are designed to help you achieve natural-looking results when removing backgrounds. These features intelligently recover details, reduce edge artifacts, and preserve sharp corners — all with minimal effort on your part.
Edge Guard
Automatic Edge Detail Recovery
Edge Guard enhances the fine details along the edges of your subject to make your cutouts look more natural — especially compared to simple alpha masking.
- Works automatically when the edge offset is set to
0(default) - Recovers subtle edge features that would otherwise be lost
- Produces a smoother transition to the background
Halo Scrubber
Removes Color Bleed for a Cleaner Look
Sometimes, background colors bleed slightly into the subject — creating unwanted halos. When you place the image on a different background, these halos can look odd or distorted.
Posternity detects and automatically removes these halos, giving you a cleaner, crisper result without shape distortion or manual tweaking.
Corner Guard
Preserve Sharp Corners, Even with Smoothing
To keep your subject looking crisp, Corner Guard automatically detects and preserves corner points.
- On by default, for sharper shapes
- Turn it off if you want smoothing to fully round all corners
- Ideal for product shots, architectural lines, or stylized cutouts
